Grinder and wire wheel..... not homemade but it works

Or mix bleach and vinegar...

Any acid will work. Vinegar (the kind which is actually acetic acid in solution ~4%) will work fine over a 12h period and is inexpensive and safe. Just scrub the part under the surface of the liquid prior to extraction - while wearing a decent mask, some of the compounds may be nastyish.

I mixed up 48% Acetone 52% atf and it seems to work well so far, although I haven't really had a terrible job to try it on yet. I have some IX strut housings with mangled gland nuts that are soaking in the aforementioned concoction now, might try to finish the job tonight, we'll see how it does. If it frees those up I will be a believer.

Electrolysis is the best way to do it in my opinion.

I know my local dealer and probably all other dealers use "Wurth" the company for their sprays.

My home-made solution in terms of bolts and thing of that nature are to take an angle grinder, grind down the middle and chisel off the head, then its usually fairly easy to screw up the rest without the pressure of the head.

Naval Jelly. But that's more for exterior surfaces.

oxalic acid

+1

Don't bother using organic solvents to remove rust, its insoluble for the most part. Poly ethereals like ATF brake fluids will be a bit better, but an aqueous solution of oxalic acid or something that can reduce then carry away is much better. Metal oxides = insoluble.
