We're just having some building work done at the moment, including ironically an extension to my garage to fit the Maser in.  After returning from along business trip I found that during the build my car has been coated in a fine layer of white building dust.  I carefully hosed the car down and gave it a gentle clean with soapy water and a lambs wool mit which was rinsed in a separate clean bucket of water.  After drying the car looked awful with patches of white all over the bodywork.  The white stuff can be removed by gentle rubbing with my finger by I'm paranoid about scratching the bodywork.  Has anyone had a similar problem and/or can recommend a way of cleaning the car without potentially destroying the finish?

Thanks

Matt

Speaking as a maser owner and a builder I empathise!

If it is cement dust  then it is at least "soft" but if it is dust from cutting items like concrete dust then it is gritty the first will adhere to the car but the second should rinse off.

The two bucket technique is recomended. You could try a very gentle pressure wash from a distance. If it isn't scratching the surface try T cut or similar. Also there are a number of proprietary cleaners available at builders merchants for cleaning up cement stains etc beware though as most of these are based on acetone which may or may not etch into or even lift the paint....try a small area say under carpet in the boot to test for a reaction and also be prepared for some hard waxing and polishing after as they will strip right back.

Hopefully that is some help.

I think that it may be cement dust as it is very fine and I seem to have some success removing this when the car is dry.  The dust is adhered to the windscreen which gives you some idea of how fine it is. I was wondering if a gentle wipe with fine microfibre cloth might do the trick?  I guess I'm preparing myself for having to use a lot of elbow grease!

Cheers

Good luck

You then are not touching the car with a cloth and the snow foam is meant to adhere the bits on the bodywork.

Status: offline 		Hi Guys,

Thanks for the sympathy, I'm feeling the love!  Anyway a quick update, I ended up going for a kill or cure approach and jet washed the bodywork twice.  I then had to T cut the roof, bonnet and rear wings followed by a couple of coats of reasonable quality wax.  Most of the cement stain was removed although it is still visible on a couple of smaller patches in the bodywork and the windscreens.  I intend to repeat this process again (no T cutting this time) at the weekend before getting my guy from Cambridge Autogleam to come out and do his stuff ('cleansing' and re-waxing) with an electric buffer.  I can't see any scratching so far, I think that T cutting wil he helped remove the stain and any associated scratches during the stain removal.

I wish I had taken some photos of how bad it looked but was so distraught that I didn't think I would want to be reminded of it.  I'll keep you posted, and thanks for the advice.

Really bad for the paint, don't use it again.

Status: online 		As WGG says stear clear of T Cut and abrasive cutting agents/polish etc...the paint on the roof is not that thick and you run the risk of cutting down to the undercoat.

There are a number of 'clays' on the market which will lift deposits off the paint rather than rubbing them off.
