Need some suggestions here. Next week I'll be painting the inside walls of a friend's garage. She owns a cool old car that throws out exhaust every time she fires it up, leaving about a 3 foot diameter black soot/exhaust spot on the wall. Any ideas on how to clean that **** up before I paint? It's drywall, not plaster.

Sounds like she is going to have the same problem after you finish painting. Why not get a piece of stainless and attach that to the wall where the exhaust hits. It will be much easier to clean and you will not have to clean up the soot before you paint.:beer:

Scrub what you can. Then kilz primer.

But like mscott said it will happen again unless something is done to prevent it

Believe me, as a sheet metal worker that was my first thought. However, I left out the fact that her boyfriend is moving in (supposedly) and his 3 motorcycles will be in the garage, and her car will get kicked out into the street. She wants me to get the garage "ready" for him, which makes me feel a little weird...I mean, I wouldn't want some other dude getting MY garage ready....:lol:

I'd cover that part of the drywall with an FRP panel. Much more resistant to dings, stains, etc. than painted drywall, and very easy to clean. I've got it on the walls in the garage in areas that get bumped or dripped on regularly, and I really like it. I'f we're talking about a small spot (4' x 4' or less), 3M 90 spray adhesive will adhere it forever. Bigger areas, use a troweled-on FRP adhesive.

Paint the wall chalk board flat black and frame it and put some chalk and an eraser on it for messages. Sounds like you will keep having to clean it up if someone else parks there too.

We had a oil furnace "blow back" a few years ago. we were not home when it happened. the whole house was black. Service Master gave us a cleaning estimate of $17,000. We did it our self. We used Purple Power. Some mixed with water in a spray bottle, then wiped with a rag and using one bucket with water, then wiped again with a different rag in another bucket of water. It worked pretty well. Have been able to prime over any traces left and paint with no problem.
