I try to keep my car nice, I don't even drive it when its rainy out. To my horror I discover the whole right side has a grey cement like substance stuck all over the passenger side along the bottom and sprayed up in the wheel wells. I tried power washing it off but it's not budging. Any advice out there on what to do? I'm bummed!!

 

Pics of it ?
Feel gritty, ruff and hard like concrete ?

I had a similar scenario when my wife ran across a newly painted yellow stripe on a highway and the paint stuck to the wheel wells and body of the car. That paint stuck on the car like glue. Called my detailer friend and he recommended a spray can of "Easy Off" oven cleaner. He told me it would not harm the paint, so I sprayed it on the body and the wheel wells and waited 30 minutes and that cleaner softened the yellow paint and used a power washer, eliminating all of the yellow paint without any harm to the actual car finish.
that was my solution to a nasty scenario.
You may have to buy two or three cans to resolve your "cement " issues.
Good Luck....

Thanks, I'll try the Easy Off.

 

I would try white vinegar first. Spray it on , let it set a few minutes, then wipe off. May have to repeat a few times

 

I Googled it and Speedy Off and Back Set were the choices, vinegar will take a long time.
Whatever you use try it on a hidden spot first.
