use wd-40 + scotchbrite to get it 'clean'. when its ready for paint, it's gonna need a final wipe down, i use alcohol.

I always use dawn dish soap and water, many times over. Then a final wipe down or two with some 90% isopropyl alcohol.

Wire wheel, wipe it down with acetone ($6/qt), rattlecan.

I would stay away from the WD-40 when it comes time to prep for paint unless you are sure you can get it 100% clean.

I use a 4 inch grinder to smooth out the welds then put a sandpaper disk on it to smooth the welds out for paint. If you are using a paint gun then you can put lacquer thinner in the hopper and use it to deoil the metal and then wipe it down with a rag and repeat until the rag comes up clean, blow it dry and paint. If you're in a hurry you can use alcohol or an alcohol base brake clean to be sure the metal is dry and ready for paint.

ok, i'll try the dawn next time i pickup steel.

my bumpers do have a couple spots where the paint hasnt stuckk
