I am doing a bid on a sand blasted basalt floor. The floor is about a year old. I noticed some brown areas on some of the tiles. The contractor said that they came that way but it cleans off with a slightly acid based cleaner. I am wondering does basalt have iron in it and could it show rust stains or dark stains after w clean it? Thanks Tony
