I recall reading stories about someone using such strong solvents that they messed up the bearing. Didn't want that to happen. ^__^

If that's the case, just read ALL the fine print on the label or refer back to the maker of the stuff to find out if there are any compatibility issues using the stuff on some materials. Case in point, I like using the "Marine Clean" cleaner/degreaser made by POR-15 -- this stuff works like a charm when you follow the directions. One point I missed in the directions is that it will spot polished AL if used above a certain dilution rate. I was using it to clean my engine bay at the recommended 1/1 dilution rate (max strength), and ended up spotting the top of my Koyo radiator with some overspray. While the engine bay came out super clean, I then had to spend an hour or so hand polishing the Koyo rad to remove all the spots the stuff left behind.
