50/50 mixture of Acetone and ATF
 

I have a question...., when using a 50/50 mixture of acetone and ATF as a penetrating oil to loosen stuck parts, can the acetone/ATF mixture be stored in a plastic container, or does it have to be a metal or glass container ?? I never used it before, and not sure if it will attack the plastic.

Anybody know for sure ?

Thanks, Sal

I have had some in one of those plastic flip top squirty drinks bottles runners use. Your results may vary, test with a small quantity first.

I've used it from a plastic pump container without issue.

Thanks for the quick replies Mart and FortyNiner.

Perhaps try a small thumb pump type oil can.

I put a quart of each in a gal paint thinner can, shake it up, then fill a metal squirt can. You have to shake each time you use, it separates. Walt

I've used it in both metal and plastic containers without issue. As Walt stated, shake before use. It does work well.

I had a 5 gallon metal can of acetone that destroyed the plastic pour spout
on the top of the can from fumes I guess. G.M.

Mixed it in a plastic coffee container, and used a plastic ketchup bottle to squirt into cylinders.

That stuff WORKS!!

Nobody has ever accused me of being a 'safety nut', but I'm thinking that to my grandkids that could look a lot like a strawberry-kiwi juice drink. This debate brings up the guy who invented the 'universal solvent'. Unfortunately there was nothing he could keep it in..... And lastly, I have had that mix in a 59ab for 3 months and this afternoon I pulled the timing gear cover and cam gear and plan to haul the engine into my shop and see if it will turn. I have had good luck with it and also mmo and acetone.

Thanks to everyone for all of the good input.

My experience was that the bottle i chose was attacked. Acetone will dissolve some plastics.

Good point about safety. No youngsters in my garage, though, so didn't cross my mind.

Likewise, I have a mix in one of the condiment squirt bottles that are sold by Wal-Mart or the like. The acetone not dissolved the plastic.

Glass is best but the acetone tends to evaporate over time so more must be added for each use.

Re: 50/50 mixture of Acetone and ATF
 

I have always stored my mix in a plastic oil container. I have never had issues with the plastic melting. I keep the cap sealed as to no acetone evaporates. The concoction works great.
