penetrating oils

[monkeykiller1996]

just wondering what kind of penetrating oils that everybody uses im a fan of pb blaster but haven't tried many other kinds (wd-40 and liquid wrench)

Rd90 from one way products.

Company I work for has a contract with the supplier, so I sign out a can a week. Hah. Haven't bought a can of lq wrench or pb in 12 years.

I've heard ATF and acetone beats everything, but I've never tried it.

Its caustic and dont get it on paint. There is a tech at my job that makes his own "super penetrate". Same as what your saying only using brake clean and ATF.

It's like 5x better than pb blaster in the studies I read

Zeph uses the crap out of it. It's pretty cheap to make. 6 dollars a quart or cheaper

i have to change some 30+ year old balljoints next week(all 30 years in the snow belt) and i was looking for something better than what i usually use i don't think blaster is gonna get it done

Yeah, the ATF plus acetone works incredibly well. And is cheap! Basically ATF plus any solvent that it will kind of mix with will do the trick. Brake clean is mostly methanol, and ATF will not mix with it very well. I have tried some other things but always come back to the tried and true ATF plus acetone formula.

Hmm, I just used some Google Fu, and found some interestings.

So, grab some veg oil next time you're in the grocery store, and thin it with whatever would mix readily with oil. I'd say something petroleum based would work better than acetone even. From what I found acetone doesn't really want to mix with ATF.

I think I'll try veg oil and gasoline right now and see what they do.

EDIT: Just mixed up some kerosene and veg oil. They mix perfectly, and so far they are staying mixed. I will let it sit overnight and post another pic, but as of now I'm taking this to work to try out. Oh, and funny enough it smells very much like PB Blaster. Hmm.

A lot of guys on Garage Journal like Kroil, but you can only get it direct from the mfg.

I bought mine from the local parts store. Pricey but I'm impressed with how well it works.

i think im going to try the atf and acetone i already have those thing laying around maybe if i keep soking it for the next week i can get the nut off by hand :glasses2:, the kerosene and veg oil thing sound interesting too
