Penetrating Fluid & other magic juices


Recommended Posts

Figured this is something we all come across - rusted PITA hardware, and all the various products we use in attempts get get unstuck.

I have found this stuff to be better than most of the other penetrating fluids, only need a few drops and give the bolt some tapping to set up vibration and it works.

 

I get this at my local HVAC shop, only a few bucks for a bottle.

 

What else have you found that works?

If they didn't call it penetrating oil or rust remover my expectations wouldn't be so high and I wouldn't have such a low opinion about how effective they were. I always use heat and WD-40. That compo seems to work. Heat and cold shock and repeat.

After years of using WD-40 the 510 wagon rusty bits just wouldn't cooperate. I tried PB Blaster and it worked better. The horn bolts, rear brake adjusters, and wiper pivot bolts came out without breaking among other things.

There is a great YouTube video that has penetrating fluid tests.

I heard about the 50/50 mixture of ATF and acetone twenty years ago and have been using it since then, it works well.  The only real problem is finding a spray bottle where one of the materials in the pump mechanism doesn't get melted by the acetone, I've found a few over the yrs that hold up for 5-6 yrs but when you go to buy another one you have to start the hunt all over again.

One of those pressurized air cans maybe? The type that has a schrader valve. These can be used for brake cleaner, not sure about acetone and atf.

Those are what i have. There expensive but they have rebuild kits for them, so can really get some time out of them. Ive had my current one for about 16 years.

Amazon has them for $30 otherwise any of the major part stores carry them but there significantly more expensive.

Thanks boys, great idea!
