Concrete splashed on car - solutions?
Discussion
Morning.
Our builders have splashed concrete - looks like a bit of sand and cement- not great dollops of aggregate on my neighbours car. We’re not living there at the mo so I haven’t seen it but they are great neighbours and it’s a nice car in one of BMW’s individual or rarer colours
I’d like to go and clean it off this morning. White vinegar and warm water is suggested on line. … anything else you’d use? Is there a product at Halfords
Advice please.
(Mods: I’ve put this in gg as I’d hope for. Reply this morning, please don’t move it to the detailing forum yet)

What shoddy workmanship. If I were him I'd get the builders to pay to get it sorted properly.
I do not know how it has happened. The skip is 4 to 5 feet from the near side of his car with a massive hedge in the way. If it has actually damaged the paint it is likely an insurance public liability claim. However my hope is that paintwork on modern cars is a bit tougher. It puts up with a lot going round the m25 etcIf it's dry it's not coming off without at minimum a bit of a polish after if it's a nice paint colour. For reference I deliver cement for a job so I've tried most things, if it's small splatters you might win but if it's big lumps it's going to be a struggle.
People online are saying vinegar because it's acidic, it's not strong enough though. Go to B&Q or wherever and get some acid brick driveway cleaner, dab it onto the bits of concrete with cotton wool earbuds to avoid paint contact and then jetwash it off.
I tend to get a lot of concrete dust on my car at work, the only way it comes off is doing a 50/50 mix of the strong acid cleaner we have, spraying it on and leaving it for 5 minutes. For lumps on the wheels I spray it on neat and you can see it reacting with the concrete and then getting the jetwash nozzle close will lift it

Firstly it needs someone who knows what they are doing. I can only imagine what it would look like after your builders have put some brick acid on it and rubbed it with a cloth......
It has sand in it, so cleaning it with a cloth is going to reveal a scratched to f
k panel once the water evaporates.
If it was my car I would be trying to get it off with a jet washer and touching the panel as little as possible. If iI owned a nice BMW in an individual (and probably impossible to match) paint I would be furious.
I would imagine putting brick acid on paintwork and wheels is a sure way to take the lacquer off and ruin the paint.

Could just be splashes from the ground his side in the rain???Austin_Metro said:

At the moment your builders are liable, and they'll claim off their insurance if they have to.
The moment you touch it?

That has occurred to me. But I don’t think my 6ft 4 builder has the touch of a ballet dancer either … I think I am more careful. At the moment your builders are liable, and they'll claim off their insurance if they have to.

Thanks spaceman. You must have expertise in this, given your job! Hoping it’s small splashes. People online are saying vinegar because it's acidic, it's not strong enough though.

Thanks all for positive input.
This is what you want AutoSmart Congo concrete remover - https://autosmart.co.uk/products/beton-go-ccon114d
I would earnestly advise you to stay away from this and let the builder's PL insurance take care of it.
I'm just going through this with 2 cars with about the same size blobs. Unfortunately it was 2 days before we notived that the cars had been splashed, by which time it was too late. The cars involved are a 2 month old Volvo (Arval business lease) and my private car (5 years old).
The specialist chosen by the insurance first tried removal on my car, but you could still clearly see where the blobs had been. The front end is being resprayed in early November. Arval have just instructed us to put the Volvo into their chosen specialist.
I fear it's going to be quite expensive, and the moment you try something you're leaving yourself wide open.

Yeah that's a builders insurance problem if the owners of the car are particular about its condition, you aren't fixing that to a standard without a few hours work and a proper polish at best.
If they're not that bothered and won't notice then a bit of acid and a jetwash will get that off. Polish and wax the whole car and give it some tyre shine and they'll think that they've won
