how do you remove cement from your car?

Question

Some of you are wondering how I got cement or concrete on my car, well I really don't know. I think I got it while driving alongside a cement truck. There is also alot of highway construction going on in our city. I have splatters of it on the car. Thank you for all of your answers and help.

PS - I don't have a mean ex boyfriend and no one hates me....

Answer 1

YOU most likely would like to keep some paint so listen, tap with a small hammer to remove what you can what is left use the same stuff you use to clean the pool. some foaming may happen rinse with hose and apply again. soon you will be down to the paint with a light gray haze. use good wax to get rid of the haze. be gentel be careful and take your time. this can be fixed.

Answer 2

Cement has high compressive strength and low tensile strength. So, assuming it has dried, I would try tapping from the inside. Or cleaning the area around the cement, covering it with a clean heavy cloth and tapping that area around the cement very lightly, with a rubber mallet. A little flexing or vibration should knock it off. I wouldn't strike over the cement itself though, as that would likely ruin the paint. The idea would be to bend the metal slightly thus breaking the weak tensile bond between the cement and the paint/wax.

Good Luck! :D

P.S. Cement is minerals that form a crystaline structure. Chances are that those crystals grew right into the paint, and that paint will come off with the cement. But maybe you're lucky and had plenty of wax on there.

Cement? I'm guessing you're talking about concrete, because "cement" is a white powder (used along with several other ingredients to make concrete). I'll also assume you're talking about concrete on the OUTSIDE of your car. Here you go: if the car's finish is still pretty good ... not old and extremely faded, you can use LOTS of water and try to pry the blobs of concrete from the paint CAREFULLY. DON'T try to break it up or you'll wind up scratching the paint. It should come off if the finish is good and the last coat of wax was applied less than, say, 2 years ago. If the car's finish is old and very rotten, forget it. If it's on plastic or rubber parts of the car and has thoroughly cured in crevices of the vehicle, leave it alone. It will either weather off, in say, 2 or 3 years, or it's permanent. In any case, don't park there again !!

Answer 4

Don't be in any hurry to get it off, definitely don't try to scrape it off if the area is visible. I would suggest using a gas powered pressure washer and try to blow it off and then possibly polish this area up with compound and then wax the car to prevent stuff from adhering so well in the future.

I love that answer that says I don't think you should put cement on your car. Heh. I'll second that.

Answer 5

Cement? Sounds like you have a very mean ex-boyfriend!

Answer 6

I had concrete get splattered on a metal door in my house and it was there for a long time, since I thought I couldn't get it off.

On day I made a bucket of simple soapy water and kept it wet until it softened up enough around the edges until I was able to get it off. This was with a sponge, I didn't use anything rough. Mine came off and it was floor concrete, I hope you have good luck.

Answer 7

Depends on where the cement is on the car.

Answer 8

If the car was mine, I would begin with a self service car wash wand, turned to wash...see if that will loosen it. It should wash right off. The pressure from the water in the wand should be sufficient to dislodge it. If it is under the wheel wells, do the same thing, except you may have to scrape some of it off since that surface is rough, allowing it to cling more.
Good luck with it.
...jj

Answer 9

Simply use Car Wash - the best produce of AMWAY. It's a magic.

Answer 10

soak the spots with vinegar to loosen the cement
