damn chunk to the right of the photo is really stuck on there. Tar remover soaking in it didn’t do anything, last thing I want to do is pick at it with some scraping device.

Maybe try something plastic like a credit card or plastic pry tool? Thats in a tough spot. Maybe a little heat from a hair dryer or heat gun could help as well.

Ive had good luck with soaking a paper towel with goo gone for a few hours and scraping with a plastic squeege. Maybe try heating it up and poking holes in it with a needle then soak.

Heat.

I'll try that. Pierce it and soak it way longer with bug/tar remover or googone.

I use this stuff from the dollar store called Awesome Stuff. Yellow liquid in a spray bottle. Its absolutely amazing on tar and brake dust. Better than any wheel cleaner I ever tried.

I was more than skeptical when this young kid at an auto parts chain store recommended it. I was shocked when I tried it. And so impossibly cheap!

When I first got my winter beater, G37xS, it was highly neglected, and must have had a seized caliper at one point that lead to rotor being ground up. There was crazy imbedded chunks of rusting iron dust in wheel crevices. It had rehardened into something solid and hard as...iron.

Wjen nothing else worked I did eventually try picking at it, but only a sharp metal pick would do anything. That left damage to the wheel. That is when I got the Amazing Stuff recommendation, and was desperate eno to try anything. Sprayed that stuff on, and in minutes it started dissolving the iron back into particles. It just wiped off.

You gotta really hose this product off a lot to get it all off. I don't know how caustic it migjt be to wheel clear coat, so don't want any left behind.

Wouldn't use it on the regular on expensive wheels, as not sure it doesn't eventually eat the finish. Its pretty caustic feeling if you accidentally breath any of it in. But for when nothing else is working, its perfect.

I poked a few holes, shifted around the upper layer to expose to center, and soaked it severely. I fashioned a small crater with microfiber and had a puddle of tar remover working at it. Took about 15 minutes before it started getting soft enough to attempt to remove with a plastic pick/tooth picks. Eventually got it all off.

Will keep in mind the "awesome stuff" for the future of anything intensively stuck on, though it does sound quite caustic.

A word of caution. I've rubbed with goo gone on a painted surface before and actually damaged the paint. I think with a careful application of heat and some rubbing with microfiber and little goo gone you should make quick enough work on this to not have paint issue.
