Worlds best Penetrating fluid
Many years ago a crusty old mechanic (neighbor) showed me this and I have been using it ever since. If you Google this formula you will find several tests of commercial penetrants vs this formula and this always comes out on top. I personally used this to free up rusted in cylinder sleeves in a Triumph TR4 engine I rebuilt. Soaked them down for weeks and they all broke loose with a wood block and big hammer. The guy I bought it from said the block was junk , said he tried everything.
50/50 mix of 100% Acetone and ATF (Automatic Transmission Fluid).
Pour in small spray bottle. Liquids will separate so need to shake well before spraying on rusty parts.
Spray on let it soak and repeat as needed.
There is nothing better.
Insanity: Doing the same thing over and over and expecting a different result.
