White spots on drive way

Yup, tire shine. Armor all ect will cause it

Old, i know. I’ve seen a propane torch get rid of oil stains, maybe worth a try. … one day.

Your still thinking of it as a stain. It’s not it’s more similar to you sanding the paint of your car . When it gone it’s gone. The white stains are from chewing the top coat off chemically

I know armor all does it so it’s not as simple as eating the top coat. In the armor all case it’s sealing the concrete

Armor all used to have some strong stuff in it . It actually voided the warranty on a set of tires I had. This was several years ago it probably different now. I was told the high amount of alcohol was the reason. I can’t imagine alcohol could damage concrete though

I’ll take your word for it. Now i can imagine it, the product was applied to tire/wheel, then the auto was moved a little forward or backward to make sure it was applied evenly on tire.
