Is that better than commercial penetrants like PB Blaster, or is that just one of those things mechanics tend to use because they have it sitting around I have a 100 year old cast iron screw jack, massive thing, that I am trying to free the screw up. PB soaks right in, hesitant to use heat because cast iron.
I know mechanics have used transmission fluid forever. I have used this mix successfully on several occasions. I keep Kroil and seafoam deep creep on hand as well,they both work good.
