How we work
The materials matter
A headstone is not a patio. What you put on it stays in the pores of the stone for years. We use the same class of products conservators specify for monuments — not what is under the kitchen sink.
D/2 Biological Solution
D/2 is a nearly pH-neutral biological cleaner developed for masonry, marble, granite, limestone, and other memorial stone. It lifts mold, algae, mildew, lichen, and air-pollutant staining without acids, bleach, or salt residues.
It is biodegradable. It does not etch glass or metal. Conservators trust it on work that cannot be replaced — including monuments in the care of the National Park Service. The National Cemetery Administration selected D/2 after a multi-year study of marble cleaners meant to reduce damage to historic government headstones.
We use it because it treats the growth that is actually eating the stone. Lichen and algae do not just sit on the surface. Some release acids that dissolve the face of the memorial. D/2 reaches that growth. Soft brushes and clean water do the rest. No pressure washer. No wire brush.
The stone often continues to lighten in the weeks after we leave. That is D/2 still working, not a half-finished job.
Why we will not use household cleaners
Bleach looks dramatic the same afternoon. The salts it leaves behind keep working after you drive away. They yellow marble, roughen the surface, and pull the stone apart from the inside.
Vinegar, brick acid, and natural” acid hacks dissolve calcium-based stone — marble, limestone, some older markers. The letters frost. The polish dies. That cannot be buffed back.
Pressure washing strips the softened face of the stone, rounds carved edges, drives water into cracks, and can tear remaining lettering paint out of the grooves.
Wire brushes and scouring pads scratch granite polish and chew softer stone. If the tool is harder than the memorial, it does not belong there.
A cheaper cleaner is not a kindness. It is a faster way to age the stone.
BEECK Monument Lettering Paint
Once the stone is clean, the name still has to be read. We refill carved letters with BEECK Monument Lettering Paint — a mineral silicate finish made for monuments, granite, marble, and masonry.
It is not hardware-store enamel and not craft acrylic. BEECK uses a potassium silicate (water glass) binder. It bonds with the mineral surface instead of sitting on it like a plastic skin. The pigments are inorganic and UV-stable, so the color is meant to hold in weather, not fade after one Central Valley summer.
Because it is breathable and non-film-forming, moisture can leave the stone instead of getting trapped under a coat of house paint. That is why mineral lettering belongs on a memorial and porch paint does not.
We restore the letters that are already cut. We do not change the font. We do not paint a name that was never there.
In short
D/2 for the stone. BEECK for the letters. Soft tools only. The goal is a memorial that looks tended — and is still intact ten years from now.
