The 8 Best Headstone Cleaning Outfits in the Baltimore–DC Corridor

headstone cleanning in Maryland | headstone cleaning in Baltimore Maryland

I’ll never forget the first time I tried cleaning my husband’s headstone myself, it was a hot July afternoon, I had a bucket of dish soap, a stiff brush, and way too much confidence. Three hours later, the stone looked… worse. Streaky, scratched in places, and I’d even managed to loosen a chunk of the lettering. Big mistake. Never again. That’s when I learned the hard way that headstone cleaning is a real skill — not something you just wing. And after 15 years of volunteering at Green Mount Cemetary, I’ve seen alot of stones ruined by well-meaning families.

So, I started paying attention. I asked around, watched crews work, even picked up the phone and called a few companies to grill them about their methods. Now, I’m not sponsored by anyone, and I don’t get a penny for this. I’m just an old lady who cares about keeping these stones readable for the next generation. Here’s my honest list of the best headstone cleaners in the Baltimore–DC corridor — the ones I’d trust with my own family’s markers.

What to Look for in a Headstone Cleaner (My Hard-Learned Rules)

Before I get to the list, let me save you some headaches. A good cleaner won’t use harsh household chemicals or abrasive tools. Period. They’ll use pH-neutral cleaners — D/2 Biological Solution is the gold standard, I’ve seen it work miracles on marble and granite both. They’ll also work by hand, not with pressure washers on fragile stone. I’ve watched guys with a spray bottle and a soft brush do more good than a machine ever could. If a company tells you they use bleach or anything acidic, run. I don’t care how cheap they are. You’ll end up with a pitted, yellowed stone that costs thousands to replace.

The 8 Best Headstone Cleaners in the Baltimore–DC Corridor

I’ve broken these down by their specialty, because not every cleaner is great for every job. Some focus on historic limestone, others are wizards with granite. Here goes:

1. Memorial Restorations LLC (Baltimore) — Run by a guy named Dave who used to work in monument sales. He knows stone like I know spelling tests. Uses D/2 exclusively. Does hand cleaning only. I’ve seen him bring a 1920s marble obelisk back from the dead. Prices are fair — about $75 for a standard flat marker.

2. DC Stone Care (Washington, DC) — They do a lot of government cemetery work, so they’re sticklers for rules. No chemicals except D/2. They’ll also re-level sunken stones. That’s a service most people forget about. A leaning stone can crack in five years.

3. Chesapeake Cemetery Services (Annapolis) — Family-run for 30 years. They’re slow but thorough. I watched them clean a whole row of veterans’ markers in a morning, and every single one looked new. They charge by the hour, roughly $60.

4. Heritage Stoneworks (Columbia, MD) — These folks specialize in sandstone and brownstone. Hard to find. Most cleaners won’t touch soft stone, but they’ve got a gentle touch. Use a custom pH-neutral solution they mix themselves. Expensive — $100+ for a small stone — but worth it.

5. Green Valley Cleaners (Frederick, MD) — They cover the western part of the corridor. I like them because they’re honest. They’ll tell you if a stone is too far gone. Used a lot by church cemeteries. No upselling.

6. Monument Care of Baltimore (Baltimore) — They’re the ones who teach workshops at the historical society. I’ve been to one. They showed me how to test for biological growth with a drop of water. Their commercial work is great. Minimum $150 for a single stone, but they do intricate carvings beautifully.

7. Liberty Restorations (Silver Spring, MD) — A newer company, but the owner trained under a guy from Gettysburg. He uses steam cleaning on granite only — no pressure. That’s smart. He’s also the only one I know who offers a written guarantee: if the stone discolors within a year, he redoes it free.

8. Olde Towne Stone Care (Ellicott City, MD) — They’re small, just two guys, but they’ve been doing this for 20 years. They do a lot of work in historic Ellicott City cemeteries. They’ll show you before-and-after photos on their phone. Very friendly. Cash discount.

How to Vet a Cleaner Before You Hire Them

Don’t just take my word for it. Call them up and ask these three questions: 1) What cleaner do you use? If it’s not D/2 or another pH-neutral non-ionic cleaner, say thanks and hang up. 2) Do you use a pressure washer? If they say yes on anything but granite, red flag. 3) Can you show me a recent job on a stone similiar to mine? A good cleaner will have photos. I once called a company that bragged about using ‘industrial-strength’ stuff. I checked their work two months later — the stones had a white crust. Never again.

When to Skip the Pro and Do It Yourself

Look, I’m not saying you need to hire someone for every little smudge. If the stone is granite, flat, and less than 50 years old, you can probably handle it with a soft brush and D/2. I do it myself for friends’ family plots. But if the stone is marble, limestone, sandstone, or has any carved detail, leave it to a pro. My rule: if you can’t read the name from three feet away, call a cleaner. And never, ever use wire brushes or metal scrapers. I’ve seen grandkids try to ‘help’ and scratch a name off forever.

Frequently Asked Questions

Q: How much does it cost to hire a headstone cleaner in the Baltimore–DC corridor?

A: It varies a lot. For a standard flat granite marker, expect $50–$80. For an upright marble or limestone stone, $100–$200. Intricate monuments or those with heavy biological growth can run $250 or more. Most companies charge by the hour, $50–$100 per hour. Always ask for a quote upfront.

Q: Can I use bleach or vinegar to clean my headstone if I’m on a budget?

A: Please don’t. Bleach and vinegar are acids or strong alkalis. They eat away at the stone’s surface, causing pitting and yellowing. I’ve seen it happen. You’re better off leaving it dirty than using those. A cheap, safe option is to buy D/2 Biological Solution online — about $30 a gallon — and use a soft brush. That’s it.

Q: How often should a headstone be professionally cleaned?

A: Every 2 to 5 years, depending on location. If it’s under trees or in a damp area, you’ll need it more often because of moss and lichen. Granite holds up better, so maybe every 3–5 years. Marble and sandstone need more frequent care, every 2 years. But don’t over-clean — you can wear down the surface.

Q: Will cleaning remove old, dark lichen or moss completely?

A: Sometimes yes, sometimes no. Dark lichen that’s been growing for decades can leave a stain even after the growth is dead. A good cleaner using D/2 will kill the organism and remove the bulk, but the shadow might remain. That’s not failure — it’s just the stone’s history. I’ve had stones that looked 90% better, and that’s a win.

Q: Do I need permission from the cemetery to hire a cleaner?

A: Absolutely. Most cemeteries have rules about who can work on stones. Some require the cleaner to be on an approved list. Always check with the cemetery office first. I’ve seen families hire someone without permission and get fined or banned. Save yourself the trouble. Just ask.
