my evo 8 has been running way to rich, i am putting a 02 sensor on it and had it tuned , but before that it was running so rich the bumper has black carbon on it on the bumper around the tail pipe and some on the actual trunk like it was misted , how can i remove that with out damaging the paint ?

 

In the navy we have wash pads to wash the jets with. Takes off just about anything. And the closest civilian thing is the mr clean magic eraser. it took the brownish black crud off my bumper with little effort

 

Go get some Simple Green degreaser from Home depot it's safe for your paint and is strong enough to do the job it works good on your motor and rims also. Read the directions for mixing strength for your application.

 

I actually used a bug & tar remover spray from advance auto...I think it was turtle wax that made it...I was really surprised...worked well...Or you could just clay bar it...I'm sure that would work well too....

 

sweet thanks guys this site is the best lol the power of the web

 

how long has the carbon been on the bumper? I just used water/soap to wash off it off mines.

 

Wash the car and then clay the bumper, apply some wax/polish to allow it to come off easier in the future.

 

Mr. Clean Magic Eraser works wonders, if you can't find one local use simple green diluted in water. Either way will work.

 

I've always used this stuff with great results. Clay bar should work also

 

This is what I would suggest. I also use Eagle 1 Never Dull on my RexSpeed carbon fiber exhaust cover which really brings back the look and takes off the caked on crap.

 

goo gone?

 

brake cleaner for the tough stuff

 

simple green works well..

 

acetone

 

are you kidding me?

Claybar works well, I'd go that route before heading to the solvent section at home depot.
