My floor was poured in 1955. It had
oil grease and brake fluid dog p... stains, deer gut blood ...... you get the picyure. I bought some stuff a one part from a guy in Long Isl NY he had pre instructions wash and etch. I used a comercial detergent on the
oil areas 2 or 3 times. Then I etched & etched & etched until there was no more fizzing then etched again. No problems been down 9 months. YThe only thing i would do over was to not park my cars as soon as I did as the black from the tirre leaked into the paint. I didn't do it after it cured for a few more days. This only happened were the cars sat for awhile I didn't do it were I drove on the floor. Maybe I should have sat them on some card board. If you want Ill look up the name of this stuff
