Wet Concrete on paint?
« on: 06 January 2017, 14:49:24 »

I have what appears to be wet concrete drops on the 3.2, on the front wing it looks like something has dripped on.

It's a bugger to remove with normal soap water, with a finger nail it kind of comes off but still bloody hard work.

What's best to use? White Sprit or even petrol?  :-\ - Concerned these would be too abrasive?

Concrete is very abrasive and also burns due to the high cement content.
How long has it been there?
 I would use lots of cold water if it`s only today and carefully try and remove with a sponge or the edge of a plastic scraper.

The only chemical that is designed for concrete splashes is brick acid, not the sort of thing you would put on your car.

It may need t cutting afterwards depending how bad it is.

I think it's concreate, it appeared I *think* after I parked in an underground car park.

It's been on there for a several weeks now, since before Christmas  :-X

Shame  you don`t  have proof, you could have got them to pay for it  :(

Somebody else might have some better ideas but I would maybe try some dilute patio cleaner (1 part cleaner to 4 parts water) or wonder wheels, it`s the same stuff, and agitate it with a brush. Have a hose pipe to hand and rinse thoroughly every time as it is Hydrochloric acid and you don`t want it on any bare metal.

Which is actually pretty much the same stuff standard alloy wheel cleaner is  :y

Looks like pigeon poo to me....which is possible in an underground carpark...its probably warmer than being outside at the moment so its possible one or two of them were lurking amongst the pipes/cables overhead.

Unless you parked in a carpark still being constructed.....I don't see where concrete splashes could have come from   :-\

Bird poo is just as bad.....unless washed of quickly...it will mark/stain paintwork.

In an underground car park I would imagine it's pigeons in the rafters. Don't know what they eat lately but their shite is a devil of a job to shift and leaves a faded mark on the paint if left too long. I soak a cloth in hot water and stick it over the shite to soften it up before attempting to fully remove. Hopefully it's just that.

Did not look like pigeon poop, but could well be.

Good shout on hot cloth  :y - Will try that  :)

When I first read your post I thought that, going on the size of the patch, it could be seagull sh it? Are you near the sea? Same treatment as YZ250 suggested, long soak first and gentle scraping with a plastic scraper.
Hope it works for you.

As had been said soak with hot soapy water not detergent after a while gently rinse with clean water and wipe off inspect for damage to the laquer if not to bad carfully polish with t cut. Worst case sinario is it may be a repaint if the base coat has been affected or re laquer of it is only laquer damage

When I'm near the coast, I notice that the bird shite has sand in it where the gulls have scavenged on the beach. It looks gritty and needs soaking to loosen it up. It depends on where the culprit had been dining as to what it fired at your car.  :)

Front of mine got absolutely mullered when parked under a tree in some naff Ipswich hotel last month.

The rain has washed off the majority now...  ...but some still remains ::)
