Headstone Cleaning FAQ — San Mateo, CA
What cleaning methods do professional headstone cleaners use?
Professional headstone cleaners typically apply D/2 Biological Solution, allow it to dwell, then gently scrub with soft natural-bristle brushes and rinse with low-pressure water. This safely removes lichen, moss, algae, and biological staining without damaging marble, granite, or limestone.
How long does a professional headstone cleaning take?
A standard cleaning takes 30 minutes to 2 hours depending on the stone size, degree of soiling, and type of material. Severely neglected stones or those with deep lichen penetration may require multiple visits.
Is bleach ever used for headstone cleaning?
No reputable professional uses bleach on memorial stones — never apply it, as it can accelerate the erosion of marble and limestone and leave residues that promote future regrowth. Conservation-grade cleaners like D/2 are the safe, recommended alternative.
How much does professional headstone cleaning cost?
Pricing varies by stone size, condition, and region, but most professional cleanings range from $75 to $250. Full restoration services — including re-setting, re-lettering, or consolidation — may cost more.
