Cleaning Industrial Grime and Moss in Tacoma
Tacoma is hard on stone. Between the constant drizzle and the traffic along I-5 and South Tacoma Way, the monuments get filthy. It isn't just the moss you get in a quiet yard. In places like Oakwood and Tacoma Cemetery, the headstones are covered in a thick, black grime. It is a mix of exhaust soot and algae. It turns the granite black. When it rains, that coating turns into a greasy slime that feels like ice if you step on a flat marker.
The ground is also soft. The soil here stays saturated for months. Heavy monuments slowly sink into the mud. We find flat markers that have completely disappeared under the grass, and uprights that are leaning because the foundation washed out. Families searching for headstone cleaning services near me call us to strip off that heavy industrial bio-film and to lift their sunken family markers back to the surface.
Removing the "Tacoma Grime"
The black coating on Tacoma headstones is stubborn. It bonds to the rough rock-pitched edges of the monuments. It is oily from the traffic fumes. You can't just hose it down. The traffic grease repels the water. You spray it, and the water just runs off the surface without moving any of the dirt.
We use a cleaner made for industrial grease. It dissolves the oil holding the dirt to the stone. We let it sit, then we scrub it. You can watch the black sludge run down the face of the marker as we work. It makes a mess, but when we rinse it, the stone is grey again instead of black.
Cleaning Sandstone and Concrete Curbing
Many of the older family plots here are bordered by low walls of concrete or sandstone. These materials act like sponges. They soak up water and grow thick mats of moss.
We clean these by hand. We kill the moss first so it dies and lets go of the stone. Then we brush it off. If you leave that moss, it keeps the concrete wet. When the temperature drops, that water freezes inside the stone and breaks it apart.
Lifting Sunken Flat Markers
The ground in Tacoma stays wet all winter. It gets soft. Flat markers, especially the military ones in Mountain View, settle deeper every year. The grass creeps over the edges until the stone is gone.
We cut the sod back. Then we pry the stone up out of the mud. We pack the hole with crushed angular rock. This creates a solid pad that locks the stone in place so it doesn't sink again when the rains come back.
Trimming Overgrown Hedges
Old plantings are a problem here. Bushes planted fifty years ago are now massive walls of brush. They grow right over the stones, keeping them in the dark.
We cut them back to open up the plot. We clear the branches rubbing on the granite. The stone needs air circulation. If it stays buried in the shade, it will be green again before the year is over.
Repairing Mower Scuffs
The mowing crews hit the stones. It happens. We see black rubber marks and chipped edges on almost every plot.
We clean the tire marks with a solvent. For the chips, we use diamond files. We grind the sharp, broken edge into a smooth bevel. It looks finished and prevents the mower from catching that same jagged spot again.
