/diy/ - Do It Yourself

I used pic related on my driveway and it worked best out of anything I tried, only one that made much of a difference. But I left it on for a couple days, and it’s going to take a couple coats if it’s bad.

The pressure washer? For the concrete driveway. I think the lady who owned this place before had a roommate or a daughter with a car that leaked some oil so I’m in the process of trying to pull some of that shit out. I got pic related and tried a small spot, seemed to pull some up, so I poured the rest of the bottle this morning and I’ll hose it off tomorrow or the next day and see if it’s worth a 2nd bottle or trying a different brand.

Pic related is like a real thick liquid that leaves a layer of dense white powder when it dries and I guess it just wicks the oil up slowly, so I’m not in a rush to hose it off.
