Moving out of our flat soon and the carport being where my supra's lived for the past 1.5 years there's oil stains EVERYWHERE. Some about the size of a $2 coin - some the size of dinner plates lol
Any tips to get them off? I just tried with a small water blaster with a soap fitting on the end filled with degreaser, but that just cleaned the rest of the concrete and now the stains stand out even more LOL
HELP!!
