Thanks for sharing the tip. I just had a quick question...Did the OXYCLEAN damage the concrete or anything? I have tried Palmolive OXY and it is working pretty well but I think I need to step it up to OXYCLEAN.
I had massive amts of oil at one point (one year ago)from Jiffylube messing up an oil change. Even though I immeadiately cleaned it up, would you believe I'm still trying to lighten it to the original color? And Jiffy Lube was no help!
