Jennifer stood in front of her grandfather’s headstone, heartbroken for a second time.

The first heartbreak was losing him. The second? Realizing she’d just destroyed his memorial trying to clean it.

She’d used what seemed like a good idea – a power washer and some bleach – to remove the green moss covering his name. Within minutes, she watched in horror as the etched letters began to blur. The beautiful granite surface she remembered from his funeral now looked permanently damaged, with white streaks and pitted areas that would never recover.

“I just wanted to make it beautiful for Memorial Day,” she said through tears. “I didn’t know I was destroying it.”

Jennifer’s mistake is heartbreakingly common. Every year, thousands of well-meaning family members accidentally damage irreplaceable headstones using the wrong cleaning methods.

The good news? With the right approach, you can safely restore your loved one’s headstone to its original beauty – preserving their memory and honoring their legacy properly.

Why Cleaning Your Loved One’s Headstone Matters

A headstone is more than carved stone. It’s the lasting physical memorial to someone you love. It’s where family gathers. It’s what future generations will see. It’s how your loved one’s name and memory remain visible in the world.

When a headstone becomes covered in dirt, moss, lichen, bird droppings, and environmental buildup, several things happen:

The inscription becomes unreadable. Family members and visitors can’t see your loved one’s name, dates, or the meaningful epitaph you carefully chose.

The stone deteriorates faster. Biological growth like moss and lichen don’t just sit on the surface – they send roots into the stone’s pores, causing cracks and accelerated weathering.

It looks neglected. A dirty headstone sends an unintended message that no one cares, which is the opposite of how you feel.

Historical information is lost. For older family headstones, illegible inscriptions mean future generations lose connection to their ancestry.

Regular, proper cleaning prevents these issues and ensures your loved one’s memorial remains a source of pride for generations.

Before You Start: Critical Safety Checks

Before you touch that headstone with any cleaning product or tool, you MUST do these safety checks. Skipping this step can cause irreversible damage.

Check the Structural Integrity

Gently press on the headstone. Does it wobble? Is it leaning significantly? Does it feel loose at the base?

If yes, STOP. Do not attempt to clean it. A loose or unstable headstone needs professional reset and repair before any cleaning. Applying pressure during cleaning could cause it to fall and break.

Look for Existing Damage

Carefully inspect the stone for:

• Cracks (even hairline cracks)
• Flaking or peeling surfaces (called delamination)
• Crumbling edges
• Missing pieces
• Areas that look “powdery” or weak

If you find significant damage, consult a professional before cleaning. Damaged stone is fragile and cleaning could make it worse.

Identify the Stone Material

This is crucial because different materials require different cleaning methods. Using the wrong approach can permanently damage the stone.

Common headstone materials:

Granite – Usually gray, black, pink, or red. Very hard and durable. Has a polished, shiny surface or a matte “honed” finish. This is the most common modern headstone material.

Marble – Usually white, gray, or cream-colored. Softer than granite. Can have veining. More porous and delicate than granite. Common in older headstones (pre-1950s).

Bronze – Metal plaques mounted on stone or concrete bases. Will have a patina (greenish color) if old. Requires special care.

Slate – Dark gray to black. Often used in very old headstones. Tends to flake in layers.

Sandstone or Limestone – Tan, beige, or reddish colors. Very soft and porous. Extremely delicate. Common in 1800s headstones.

If you’re not sure what material it is, assume it’s delicate and use the gentlest methods. When in doubt, consult the cemetery office or a monument company – they can usually identify it quickly.

What NEVER to Use on Headstones (This Destroys Them)

Let’s start with what NOT to do, because these common mistakes cause irreversible damage:

NEVER Use Bleach or Chlorine Products

Bleach (sodium hypochlorite) is one of the worst things you can put on a headstone. It:

• Causes white streaking and permanent discoloration
• Breaks down the stone’s surface structure
• Leaves salt deposits that attract more dirt
• Can turn bronze green or cause corrosion

This includes products like Clorox, toilet bowl cleaners, and many “mold removers.” Even diluted bleach is harmful.

NEVER Use Acidic Cleaners

Vinegar, lemon juice, and commercial acidic cleaners literally dissolve stone.

On marble and limestone, acid causes immediate etching (dull spots and pitting). On granite, it can damage the polish and cause permanent cloudiness.

Avoid anything containing:

• Vinegar or acetic acid
• Lemon juice or citric acid
• Muriatic acid (hydrochloric acid)
• Any “bathroom cleaner” or “lime remover”

NEVER Use Pressure Washers or Power Washers

This is the #1 way people accidentally destroy old headstones.

High-pressure water can:

• Blast away the stone’s surface layer
• Force water into cracks, causing them to expand
• Damage or erase fine details and lettering
• Cause immediate and permanent erosion

Even at “low” settings, pressure washers are too powerful for most headstones. This is especially true for marble, sandstone, and older stones.

Note: Some professional monument companies use pressure washers, but they’re trained on proper PSI settings and techniques. DIY pressure washing is almost always a bad idea.

NEVER Use Wire Brushes or Stiff Brushes

Metal wire brushes scratch polished surfaces and can leave metal residue that stains the stone.

Stiff plastic or synthetic bristle brushes can scratch softer stones like marble.

Stick to soft natural-bristle brushes or nylon brushes only.

NEVER Use Household Cleaners “Because They Work Great at Home”

Products like Windex, 409, Simple Green, and similar household cleaners contain chemicals that can damage stone over time, leaving residue, causing discoloration, or breaking down sealants.

Just because it cleans your kitchen doesn’t mean it’s safe for a 100-year-old marble headstone.

NEVER Use Shaving Cream (Yes, People Do This)

There’s a persistent myth that shaving cream makes inscriptions easier to read. While it temporarily highlights lettering, it:

• Leaves chemical residue in engraved areas
• Attracts dirt
• Can stain porous stones
• Provides no actual cleaning benefit

Don’t do it. Use proper cleaning methods instead.

The Right Way to Clean a Headstone: Step-by-Step

Now that you know what NOT to do, here’s the correct, safe method for cleaning most headstones.

Note: This method is safe for granite and most modern headstones. For marble, bronze, sandstone, or very old/fragile stones, see the material-specific sections below or consult a professional.

What You’ll Need

Cleaning supplies:

• Large buckets (at least 2)
• Plenty of clean water
• Mild dish soap (Dawn, Ivory, or similar – nothing with bleach, degreasers, or harsh chemicals)
• Soft natural-bristle brushes (like a soft paintbrush or natural fiber scrub brush)
• Soft cloths or towels
• Wooden or plastic scrapers (for heavy buildup)
• Spray bottle (optional)
• Gloves (optional, for hand protection)

For tougher biological growth (moss, lichen, algae):

• Biological stone cleaner specifically formulated for headstones (D/2 Biological Solution, Wet & Forget, or similar)

Step 1: Remove Loose Debris

Start by gently removing any loose material:

• Pull away grass, weeds, and vines by hand (don’t yank – cut at the base if needed)
• Use your hands or a soft brush to remove loose dirt, leaves, and twigs
• For stuck-on debris, use a wooden or plastic scraper very gently

Don’t rush this step. Removing loose material first prevents scratching during the wet cleaning process.

Step 2: Pre-Wet the Entire Headstone

Using clean water from your bucket or a gentle spray bottle, thoroughly wet the entire headstone.

Why this matters: Pre-wetting prevents the stone from absorbing cleaning solutions too deeply and helps loosen dirt and biological growth.

Keep the stone wet throughout the entire cleaning process. Don’t let it dry out between steps.

Step 3: Apply Your Cleaning Solution

For general dirt and grime:

Mix a small amount of mild dish soap with water in a bucket (a few drops of soap per gallon of water is plenty – don’t overdo it).

Using a soft brush dipped in the soapy water, gently scrub the stone in circular motions.

Start at the bottom and work your way up. This prevents dirty water from running down onto areas you’ve already cleaned.

For biological growth (moss, lichen, algae):

If water and soap aren’t removing green growth, you’ll need a biological cleaner.

Apply according to the product instructions. Most biological cleaners work best when:

• Applied to wet stone
• Left to sit for 10-15 minutes (or as directed)
• Not scrubbed aggressively (they work chemically, not mechanically)
• Rinsed thoroughly

For really stubborn lichen: Some lichen is extremely tenacious. After treatment, it may take weeks for dead lichen to weather away naturally. Don’t aggressively scrub – you’ll damage the stone before you remove the lichen.

Step 4: Work on the Details

Use a soft-bristled toothbrush or small detail brush to gently clean:

• Inside engraved letters and numbers
• Around decorative carvings
• In crevices and hard-to-reach areas

Be patient with this step. Proper detail cleaning makes inscriptions readable again.

Step 5: Rinse Thoroughly

This is one of the most important steps.

Using clean water, thoroughly rinse the entire headstone. Make sure you’ve removed ALL soap residue and cleaning product.

Why this matters: Soap residue left on stone attracts dirt, defeats the purpose of cleaning, and can cause staining over time.

Rinse from top to bottom, using plenty of water.

Step 6: Dry and Inspect

Use clean, soft towels or cloths to gently dry the headstone.

For polished granite, you can buff it to restore shine.

Step back and inspect your work:

• Is the inscription now readable?
• Did you miss any areas?
• Does the stone look clean and well-maintained?

If you’re not satisfied with the results, DON’T immediately try stronger chemicals. Sometimes heavily soiled stones need multiple gentle cleanings over time rather than one aggressive cleaning.

Material-Specific Cleaning Instructions

Different headstone materials require modified approaches. Here’s what you need to know:

Cleaning Granite Headstones

Granite is the most durable and forgiving headstone material, but it still requires care.

What works:

• Water and mild soap for routine cleaning
• Biological cleaners for moss and algae
• Soft brushes
• For polished granite: You can use a small amount of household glass cleaner (like Windex) for a final streak-free shine, but ONLY if you completely dry and buff it – don’t leave any residue

What to avoid:

• Abrasive cleaners or scrubbing pads
• Acidic products (even though granite is more acid-resistant than marble, acid can still damage the polish)
• Metal brushes

Special notes: Polished granite can be scratched by hard scrubbing, so always use soft materials even though the stone itself is hard.

Cleaning Marble Headstones

Marble is beautiful but delicate. It’s porous, soft, and extremely sensitive to acids.

What works:

• Water only is often best
• Very mild soap if needed (test in an inconspicuous area first)
• Softest brushes only
• Patience – don’t try to rush the process

What to absolutely avoid:

• ANY acidic products (this includes vinegar, lemon, and most commercial cleaners)
• Pressure washing
• Aggressive scrubbing
• Biological cleaners with harsh chemicals (read labels carefully)

Special notes:

• Older marble headstones often have a “sugaring” problem where the surface becomes granular and weak. If you see this, consult a professional – cleaning could accelerate damage.
• Some marble develops a protective patina over time. Over-cleaning can remove this.

Cleaning Bronze Markers and Plaques

Bronze markers are metal, not stone, and require different care.

What works:

• Water and very mild soap
• Soft cloths
• For stubborn corrosion: Specialized bronze cleaner (follow product instructions)

What to avoid:

• Abrasive cleaners or pads (these scratch bronze)
• Metal brushes
• Any product containing ammonia
• Trying to remove the natural patina (the greenish color is normal and actually protective)

Special notes: Modern bronze markers are often sealed. Older ones were not. If you’re cleaning pre-1970s bronze, be especially gentle as the patina is part of its character and protection.

Cleaning Sandstone and Limestone Headstones

These are among the most fragile headstone materials, commonly found in 1800s cemeteries.

What works:

• Water only, applied gently
• Very soft brushes
• Extreme patience

What to avoid:

• Almost everything. Seriously. These stones are incredibly delicate.
• Any cleaning products
• Any scrubbing
• Pressure of any kind

Special notes: If you have a sandstone or limestone headstone that needs cleaning, strongly consider hiring a professional conservator. These stones are often historic and irreplaceable. The risk of DIY damage is very high.

Common Headstone Cleaning Problems and Solutions

Problem: Black Spots That Won’t Come Off

What it is: Usually biological growth (algae or lichen) that’s deeply embedded in the stone’s pores.

Solution: Use a biological stone cleaner specifically designed for this. Apply according to directions and be patient – it can take weeks for dead growth to fully clear.

Don’t aggressively scrub trying to remove it immediately. The biological cleaner works over time.

Problem: White Streaks or Haze on Dark Granite

What it is: Often caused by hard water deposits, soap residue, or previous use of inappropriate cleaners.

Solution:

• Rinse extremely thoroughly with clean water
• If it persists, try a small amount of household glass cleaner, then buff completely dry
• For stubborn cases, a professional monument company can polish it out

Problem: Rust Stains

What it is: Iron deposits, often from nearby metal fixtures, lawn equipment, or minerals in soil.

Solution: Rust stains are very difficult to remove without potentially damaging stone. Consult a professional rather than trying harsh rust removers.

Problem: Bird Droppings That Have Etched the Surface

What it is: Bird droppings are acidic. If left on stone (especially marble) for extended periods, they can permanently etch the surface.

Solution: Unfortunately, etching is permanent damage. A professional monument company may be able to re-polish granite to minimize the appearance, but marble etching is generally permanent.

Prevention: Clean bird droppings as soon as you notice them (just water and a soft cloth).

Problem: Paint or Spray Paint

What it is: Vandalism, unfortunately.

Solution: Do NOT try to remove paint yourself with paint thinner or other solvents – these can stain the stone permanently. Contact the cemetery immediately and consult a professional conservator. There are specialized methods for paint removal that vary by stone type.

Problem: Heavy Moss Growth

What it is: Thick moss covering the stone, often with roots penetrating the surface.

Solution:

• Soak the stone thoroughly with water and wait 15-20 minutes for moss to soften
• Gently remove as much as possible by hand or with a wooden scraper
• Apply biological cleaner
• DO NOT aggressively scrub – this will damage the stone trying to remove stubborn roots
• Accept that some moss may require multiple treatments over months to fully clear

When to Clean: Timing and Frequency

Best Times of Year for Headstone Cleaning

Early Spring (March-April):

• Ideal for Memorial Day preparation
• Temperatures are mild
• Allows biological cleaners time to work before summer growth peaks

Fall (September-October):

• Prepares stone for winter
• Removes summer growth before it dies and becomes harder to remove
• Good temperatures for cleaning products to work effectively

Avoid:

• Winter/freezing temperatures – Water can freeze in stone’s pores and cause cracking. Never clean when temperatures are below 40°F or when freezing is expected within 48 hours.
• Extreme heat – Cleaning products can dry too quickly, leaving residue

How Often Should You Clean?

For most modern granite headstones (aff): Once per year is typically sufficient, usually in spring before Memorial Day.

For marble or more porous stones: Gentle cleaning every 1-2 years, or as needed.

For stones in shaded, humid areas: May need cleaning every 6-12 months due to faster biological growth.

For stones in sunny, dry climates: May only need cleaning every 2-3 years.

Light maintenance visits: Every few months, brush off loose debris and pull weeds to prevent them from taking root. This reduces the need for intensive cleaning.

Preventing Future Buildup

Once you’ve cleaned your loved one’s headstone, here’s how to keep it looking good longer:

Regular Light Maintenance

Visit every few months and:

• Brush off loose dirt and leaves
• Pull weeds before they establish roots
• Remove any bird droppings immediately (they’re acidic and can etch stone)
• Check for new cracks or damage

Strategic Landscaping

• Trim back overhanging trees that drop sap or provide too much shade (which encourages moss)
• Don’t let grass grow right up against the headstone base
• Consider planting sun-loving ground cover instead of grass immediately around the stone
• Ensure proper drainage so water doesn’t pool around the base

Protective Treatments

Some companies offer protective sealants for headstones. These can help, but:

• Only use products specifically designed for the stone material
• Understand that sealants need reapplication every few years
• Some monument professionals recommend against sealants for certain stone types
• Improper sealing can trap moisture and cause more problems

If considering a sealant, consult a professional monument company first.

What NOT to Do for “Protection”

• Don’t apply car wax, furniture polish, or similar products
• Don’t paint or coat the stone with anything not specifically designed for monuments
• Don’t install plastic covers (they trap moisture)

Cemetery Rules and Etiquette

Before cleaning any headstone, consider these important points:

Get Permission

If the headstone belongs to your immediate family member: You likely have the right to clean it, but check cemetery rules first.

If it’s a more distant relative or you’re doing genealogy work: Contact living descendants if possible, or ask the cemetery for permission.

If it’s in a national cemetery or historic cemetery: Special rules often apply. Always check with cemetery administration first.

Follow Cemetery Regulations

Many cemeteries have specific rules about:

• What cleaning products are allowed
• What time of year cleaning can be done
• Whether professional services must be used
• Water usage

Check before you start. Some cemeteries provide water spigots for this purpose, while others don’t allow cleaning at all (they handle it themselves).

Be Respectful

• Don’t walk on graves if possible – step around them
• Be mindful of recent burials and fresh grief
• Clean up all your supplies – don’t leave buckets, brushes, or trash
• Respect neighboring plots – don’t let your cleaning water run onto adjacent graves
• Be quiet and considerate of other visitors

What If the Headstone Is Beyond DIY Cleaning?

Sometimes a headstone needs more than cleaning. Signs that professional restoration is needed:

• Deep cracks or structural damage
• Severely eroded inscriptions that are illegible
• Sunken or tilted stone
• Broken pieces
• Extensive biological growth that won’t respond to gentle cleaning
• Historic significance (anything over 100 years old deserves professional care)

For severely damaged or historic stones, contact a professional monument conservator, not just a regular monument company. Conservators specialize in preservation and use techniques that respect the stone’s age and condition.

Real Stories: The Difference Proper Cleaning Makes

Sarah’s Story: From Illegible to Beautiful

“My great-grandmother’s marble headstone was so covered in black stains and moss that we couldn’t read her name anymore. I was terrified to try cleaning it myself after reading horror stories online.

I used Headstone Helper’s DIY kit and followed their instructions exactly. It took about 90 minutes, working slowly and gently, but when I was done, I literally cried. I could read her full name, her birth and death dates, and the beautiful poem engraved on the stone – none of which had been visible for probably 20 years.

My mom came to see it and was so emotional. She said, ‘It looks like the day we buried her.’ That’s exactly what proper cleaning should do – restore it without damage.”

Mike’s Story: Saving a Family Monument

“Our family monument is granite, erected in 1952 for my grandparents. Over 70 years, it had developed serious green algae growth and the inscription was almost illegible.

I started with just water and mild soap like the guide recommended, but the biological growth wouldn’t budge. Instead of trying something harsh, I contacted Headstone Helper for professional service.

They came out, assessed it, used their professional biological cleaner, and in a few hours had it looking incredible. More importantly, they pointed out some small cracks forming at the base that I hadn’t noticed. They repaired those before they became a major problem.

Best money I’ve spent in years. Now every Memorial Day and Veterans Day (grandpa was a vet), we can visit a monument that looks dignified and well-maintained.”

Linda’s Story: The Memorial Day Miracle

“Every Memorial Day, I visit my husband’s grave. Last year, I was horrified to see his beautiful black granite headstone had developed white streaks and looked cloudy – like someone had used the wrong cleaner.

The cemetery said they didn’t know what caused it, and I was devastated thinking it was permanently damaged. I found Memorial Merits’ article about headstone cleaning and reached out to Headstone Helper.

They explained it was likely hard water deposits and residue from inappropriate cleaning. They were able to professionally clean and re-polish it, removing the streaks entirely. Now it looks the way it did when we first placed it.

I’m so grateful I didn’t try to fix it myself with some random product from the hardware store. That could have made it permanently worse.”

The Bottom Line: Clean With Care, Honor With Pride

Your loved one’s headstone is one of the most permanent ways their memory exists in the world. It deserves to be maintained with the same care and respect you would give to any precious family heirloom.

The key principles to remember:

Be gentle. Always start with the mildest method and only escalate if necessary.

Be patient. Proper cleaning takes time. Rushing leads to damage.

Be informed. Know your stone material and what it can tolerate.

Be humble. If you’re not sure, ask for professional help rather than guessing.

Be consistent. Regular light maintenance prevents the need for intensive cleaning.

A clean, well-maintained headstone isn’t about vanity or appearances. It’s about showing continuing love and respect for someone who mattered deeply. It’s about preserving their name and their memory for children, grandchildren, and generations yet to come.

When you stand in front of that headstone after proper cleaning, able to clearly read every letter of their name, seeing the stone restored to its original beauty, you’ve done something meaningful. You’ve honored them. You’ve preserved their legacy. You’ve shown that their life and their memory still matter.

That’s what headstone care is really about.
