[Vwdiesel] cleaning injector parts

[Nate Wall]

The throttle body of the Mom's Ford Ranger was very varnished. I used "Gum
Cutter" and it did a fair job, and I ran out. I had a full can of brake
cleaner, and man, it took all the varnish off in one application. I was amazed!
I'd steer clear of rubber and plastic parts w/ it, though. Also, use an old
tooth brush and scrum the nozzles w/ it (use latex gloves and goggles too.)
