removing concrete droppings from a car

Hi anyone know how to get concrete drops off of a car? My @#$^%(&* neighbors contractor had a concrete pump truck working nearby and got drops of concrete onto my car, which have now hardened.
 
Tell your neighbor you're taking it to a body shop for estimates & he'll be expected to pay whatever it takes!
 
My answer as well. Even if you ~could~ get it off without abrading the paint (and that's doubtful) I think you'll find it will have chemically attacked the finish. It would have had to be rinsed of immediately for it to have no effect.
 
I agree that you should get estimates from a competent body shop and/or detailer.

And while the contractor/neighbor should own up to their mistake, don’t let them “take care of it themselves” by having one of the contractor’s laborers “fix it” for you. They’ll do a lot more damage that good. Either have a very good professional deal with it or do it yourself.

Haven’t tried it myself, but there’s a company called RoMix that specializes in cleaning chemicals for construction and fleet vehicles. They have a product called Back-Set that’s designed for removing concrete.

One of my favorite suppliers for car care products, Top of the Line Detailing, carries it.


PC.
 
I have a distinct feeling that I am not going to get anywhere talking to the neighbor. The concrete is all on the daily driver Beetle (a REAL Beetle with the noisy engine in the trunk) The paint is already rather faded so I am not extremely annoyed, I will go play chemist on an unseen spot and then polish it.
 
I`m no lawyer, but I suspect the homeowner is not liable. The contractor however is. They have insurance to cover just such incidents. I would be contacting them, first I would try the direct approach IE. personal visit or Phone call explaining just exactly what the complaint is. If that didn`t work then they would be either finding themselfs in small claims court or bieng contacted by my Laywer!
It is the contractors responsibility not to damage neighboring property during the course of fulfilling thier obligation to the contractee.
If you "Let it go" , In the futrue someone else will be facing the same delema you are at present. I say make them put things right.
My .02 Cents worth
 
It would not be surprising if the laws in Israel are different.
 
Oh I did speak to the contractor. He seemed to have a conceptual problem with the fact that cars MOVE, and that my car wasn't parked exactly were he had been working with concrete. Obviously after getting splattered once, I wasn't leaving it in the same location to see if he will be less sloppy next time!
He was quite willing to send one of his idiots over to scrape off the droppings, however since they probably would try using a chisel and sledgehammer for the job I will take care of it myself.
I could try taking him to small claims (my wife used to work there so we know the rules very well) but in all likelihood, it would take so long to come to court, my wasted time, etc that it really isn't worth it. After all even if I only waste one day playing with the courts I could have cleaned and polished the car several times by myself in the same amount of time.

All I was really looking for was any knowledge of methods that may work. Since concrete is weakened by acids, I am going to start out by pouring that most common weak acid we all have around the house on it, vinegar, and when that doesn't work I will move on to the de-calcifier which I know reacts with concrete. I will test it on the paint first though.
 
I do know that concrete keeps hardening so probably the sooner the better.
 
Whatever you do, don't WIPE!

err... umm... /bcforum/images/%%GRAEMLIN_URL%%/blush.gif ...okay...

Sounds MESSY though.
 
The decalcifier may work into the paint surface if there hasn't been wax applied regularly. White vinegar and patience may be the better method.

hehehehe

Wiping hard bits of concrete over the paint leaves scratches - & deep ones at that. I would almost think you'd have to attack each little bit of concrete individually, picking it off the paint rather than wiping, swirling it off.

If the wax job is good, you might be able to lift it piece by piece.
 
Th stuff is Ancient Roman Epoxy. Even if the finish is well waxed, I fear the reaction as the stuff cured made it bond to the surface. And trying to rub it off WILL result in gouges. Stuff is as abrasive as, well, sand.
 
Well for a little report.
Last night I put a liquid designed to remove hard water build up. (a very weak acid) Within about 1/2 hour it had significantly softened up the concrete, and with my fingernail I was able gently scrape the concrete off. Paint finish looks about as good as it was before. No signs of any reactions with the paint itself. It is just going to take allot of patience to get off all the splotches without scraping anything up.

Once I get the crude off a quick polish job should make it look fine.
 
Glad ya found some solution, Yis. I guess patience is now your most important tool. Also pleased to learn it didn't chew into the paint. A pleasant surprise.
