I was told by the local tire shop that I use & trust to never ever put metal caps on the TPMS valve stems. He said they often weld on due to corrosion. Plastic caps for this guy.
Almost forgot. Happy Birthday Dave!

thanks. In case its not obvious the acetone mix is probably more damaging to paint, plastic bits, etc. Maybe you want to reserve that for really tough situations.
I'm rather surprised pb blaster did so poorly. Was it the original penetrating catalyst stuff? They sell a whole line of different lubes now. -

The other problem with the acetone mix is that it separates out over time, and the acetone evaporates.
I use Kroil.......it works. -

Just mix the ATF and acetone as needed.
Something else I've used for years as a rusty nut release, is beeswax. I heat the nut with a torch just hot enough that the beeswax melts and wicks into the joint between the nut and bolt or stud. Candle wax works pretty well also. All the ships I've worked on have beeswax in the shop for just this purpose.-

Aero Kroil FTW! Over the years I've used many types & the Kroil is the best so far for this old wrench twister.

I have used wax as well, particularly on exhaust fasteners, where it doesn't matter if you get them hot with the torch, but then I always wonder if it was the wax or the heat from the torch that did it!
Nah, you don't have to get it that hot with the wax for it to work.
CRC makes a product that works really well too, that freezes the parts and lets them release- pretty amazing stuff actually. -

I have used kroil and know it works well but had never heard of mixing atf and acetone. PB Blaster kinda surprises me and just recently heard of the wax trick but haven't had the opportunity to use yet.

Just adding muriatic acid into the mix.
Just be sure to use it in a well ventilated area (i.e. outside only)

I saw someone do a YouTube video like this and the ATF mix did well there as well.

Birthday cake candle wax is awesome to use on the inside of metal valve stem caps that tend to get stuck.
