I've been asked to give a bid on cleaning cemetary monuments, but have no idea how to approach it. Most of the stones are granite or marble, with lichen and or moss and stains on parts of the stone. What chems should I use, and what is the proper procedure?
I have a 4gpm, 3600psi cold water machine. I'd have to truck water to the site.
Thanks for any help I can get here. I'd like to set my retired father up to maintain these markers eventually, and I just want to make sure I'm doing it right.
Sincerely, Paul
