Default Firewall cleaning

Anyone have a suggestion on what cleaner to use to remove black spray bomb paint from a firewall? Don’t want to disturb factory markings. Thanks

I used enamel reducer and paper towels to remove the rattle can paint...
Soak the paper towels in enamelreducer and spread over the area... allow it to penetrate then wipe off using paper towels and "chip" brushes.
IT is tedious nasty work.

hi
i used simple green on my deuce to do all the firewall/ complete front suspension/ complete front frame and it work great for me...removed spray paint overspray along with grease and dirt
generously sprayed it on and let it sit for 15-20 minutes use a soft brush and then wiped off throughly
secondary cleaning.....re-sprayed it again and wiped after 5 minutes with clean rag...and it was amazing

Ok here is one of my secrets I have been using since cleaning carbon deposits off of floor boards from rich jets and open headers on the Black RS/Z survivor. AND it is made for removing BAKED ON GREASE.
HD EASY OFF oven cleaner -
FWIW The WEAKER fume free version is useless.

X2 on the EASY OFF HD!

Something with even more toxic fumes that has saved me countless hours on a current cleaning and preservation project, Aluminum Brightener from NAPA. Removes grime like nothing else I've found but doesn't harm factory paint or EDP on underhood metal and firewall blackout. Spray, wipe it off, neutralize with water, and follow with wax.
Also spectacular results on phosphate and zinc stuff (horn relay cover, ash tray) and of course aluminum (alternator, a/c lines).

Granted not firewall but I’d use the same steps on it as well.

Zep citrus degreaser, blue scotchbrite pad, micro fiber towels, #7, & Mirror Bright Rubber & Vinyl. Oh and insert evaporust before #7 & Mirror.
