While my car was parked in the parking lot at my job last week some idiot contractor washed the concrete out of his truck right next to my car!! The entire car was covered in concrete, I thought the paint was ruined! I got home and washed the car immediatley, I was fortunate enough to get all the concrete off the paint ( Berlina Black ) however it did not come out of the top! It appears to have stained into the vinyl- I now have hundreds of white spots all over my vinyl top. What in the world can I use to clean this to get the stains out??? It looks absolutely horrible, I can't even bare to look at it- it's that much of an eyesore.

 

that is terrible...
my guess is that your car now needs some swirl removal too-
for the top, i think i would first try Raggtopp Cleaner.
(by the way, i would give it a couple of tries and use a good brush for this job).
if that doesnt work, post back here and we will find a more aggressive suggestion.

 

try any of this 303 stuff .. here

How about getting the contractor people clean it or have the top replaced by them? I can't believe the stupidity of some people. A couple of summers ago, contract maintenence workers turned the sprinklers on and hardly hit any plants, but the parking lot was watered thouroughly. Unfortunately for me, my car was the closest to the sprinklers. Plus, it was a bright sunny warm day. Can anyone say water spots???

 

Normally I'd say Renovo or 303 cleaner would work fine, but if the concrete has dried and set on your top, neither of those will take it off. I seriously think that if you know who caused the damage, you should go to them and get a new top.

 

i would get the contractor to pay for the damage.
go file a police report asap
