If it is just dust, I start with a thorough blow-gun job, followed by some Gunk FEB1 Foamy Engine Brite engine degreaser. This is the only product that I have personally used that doesn't seem to leave a white residue behind.

Pressure wash and rinse it from every conceivable angle, and in every nook and cranny.

You'll know you have been thorough enough when you are wetter than your engine.:thumbup:

 

I personally would take it back to them and make them clean it, we always washed/cleaned the customer's vehicle after repairs were completed. They are the ones that got it dusty, they should at least blow it out with some compressed air at the very least. Just my personal opinion.

 

66GMC- That's about the way I was thinking too, except for some reason I didn't of the blow gun.

ppgsprayer- We got a great paint job for a good price so I don't mind doing some cleaning. I told him not to worry about it.

 

Dooohhhh !!

Just got my kids car back from the paint shop. What a freaking mess they made. His has a highly detailed very expensive motor, trans, etc all in B4 we sent it. I asked them to PLEASE tape the underside as best as possible as it has a polished stainless steel exhaust system. The engine compartment is full of S.S. braided hose, AN fittings, polished alum, etc. Primer overspray, paint overspray, body dust every where you can imagine. $5,500 for a descent paint job and 5 weeks later I am still cleaning primer, paint, and body dust. Not so sure it was worth it. As far as cleaning what you have ? Simple body dust you should be able to rinse off with a hose, overspray well it all depends what it is one. Plastic ? Metal ? Upholstery ? Aluminum ? Glass ?
Maybe ask the shop what the usually use on particular items. That way maybe they will get the idea it's not a good policy to make the paying customer clean up 'thier' mess. Could even get you a few supplies to do the job for free. My way of looking at it is I agree with PPGSPRAYER. If they are going to charge you to do a job, they should NOT create work for the paying customer. Its just bad business.

 

Lesson here is to make sure they coat the engine bay and underbody with a spray mask before they start any work and reapply it after wet sanding and before any spraying

 

It's crappy work that these auto shops do that make me do everything I can on my own. It sucks that you can't get much good work done these days. They just want your money and don't care about much else.

 

If you are going to clean the painted surfaces under the hood I would lean toward Simple Green cleaner with a soft paint brush. It will not harm the paint and will clean everything but overspray. I have used it on my Harley and under the hood of my cars for years. Good stuff.
