Well after most of us suggesting to @ocpw who posted about the muriatic stain on a drive he was looking at last night get a call from a gentleman this morning who said he’d messed up his drive and could I come look at it. Since it was close, went by and what a mess. Older guy, spry early 70’s, he and his wife’s dream retirement home in a new patio home subdivision. Only been there 5 months in their new home.
Trying to remove some just plain old tire marks on his fresh new drive, that pretty much any degreaser would have taken care of, he went and got him some muriatic and says he followed directions. He had some tire marks in different locations and he scrubbed it after he put it on. And he tried it in a few other places too. I’ll let the pics speak for themselves.
I took my own advice and told him I probably couldn’t help him, but would seek out which direction might be his best course of action. He’s a good guy whose wife is pissed as hell at him and he’s really distraught. So @gbattle or anyone else, open to ideas. I will say that the area he reapplied and scrubbed some more in the top left of the drive looks the best of what’s done. But absolutely no cream left on the treated parts.
