I used to use the ethylene glycol in a crockpot for cleaning aluminum parts. It's been years since I last used the method though I still have my crockpot. I have a bushed 2-stroke airplane engine I want to clean and cant remember what temp to set the Prestone anti-freeze to.

*if this unique aluminum cleaning method is new to you and you decide to try it, be certain you do not return your crockpot to food use no matter how clean you think you can get it. Ethylene Glycol is poisonous. This hot antifreeze though is an amazing cleaner!

as soon as you pull the part(s) from the antifreeze bath hit it with a tooth brush (don't brush your teeth with it afterwords) - anything still on the engine or muffler will scrub off pretty easy. even running it under water in a sink with dish soap helps get that crud off after the crockpot. make sure nothing is sticking out of the antifreeze or the fumes will discolor it. make dang sure you have the crock pot outside or in a well ventilated garage - don't want the fumes in your house.

I just can't remember how hot to set the temp. I can actually set the temp. on this pot. It's not just low/med/hi. That old thread link says about 225 so I'll start with that. I too ran into the tarnish one time like was mentioned. I think it was old antifrezze and it was too hot. It's fresh this time and I'll start on lower temp.

it may be nice to engrave that crockpot with "chemicals" Id hate to buy it at a garage sale. The concept of reusable glass creeps me out too because who knows what was stored in a milk bottle before its returned- steam doesnt clean the real nasties.

on topic the cooling system on a car wont have probs at 250 degrees, its just the pistons and bearings that dont like that. 220 is normal, im sure the aluminum youre cleaning can handle that and alot more.
Il add that your method sux, save the whales dude. I use an ultrasonic cleaner from harbor freight instead of so much chems. I guarantee it does a better job than antifreeze. Ive never heard of antifreeze for carb cleaning and theyre aluminum.

Ultra SOnic Cleaner's will quickly destroy any line fit moving part or bearing, "Fretting" with surface to surface vibration.

Only do it if ALL the bearing's are removed in advance and discarded.

It will do the also same to expensive jewelry and it's facet's.
I All way's want to look in the tank at a Mall Jeweler just to see what treat's may be left behind

It is not the ultrasonic cleaner that damages fine surfaces. It is the use of an improper chemical cleaner. Jewelers use ultrasonic to clean fine items with no damage all the time. I use it to clean bearings with the proper solvent with no issues. Bearings greased and returned to service have hundreds of flights.

How the heck did you guys take my thread about what temperature to use ethylene glycol at in a crockpot and end up discussing ultrasonic cleaners?

Wrongler, I used about 225F and it did fine without causing tarnishing.

Isn't it amazing how threads migrate? Some times the migration is useful, though.

I have no idea How HOT mine get : I run TWO - Kinda Like the Fire Hand Test
Next time I cook up some I'll measure it?

I have a lil- 1 quart bugger I got at Wal mart for $7.00.
It has Hot Dog Tong's, a lil- Tea basket thingy w/ a chain on it for nut's bolt's and carby part's. You just plug that in and it goe's -IT GET's HOT !

My BIG 3Lb Rump Roast one: Has a stainless soap dish screen thingy on wires so I can pick it up, and a 4" screen strainer thingy also on wires I cut the handle off. Those option's are found in the same part's department at Wal mart as the $7.00 crock pot.

Lot of time I keep the part's off the bottom off the crud that fall's out- YUKKY and amazing . I use the same Hot DOG Tong's on Both. I Alway's set it to High - Because It Get's HOT.

I also have a magnet on the end of a pocket scribe - in case I have to go fishing for a spring, a lock washer or something.

Power Dissolve is Cool: For Exterior - But if you can't the wrist pin's out, the bearing's out, the sleeve's out, or the bearing's off the crank, or the goo build up inside the muff --

Some way you have to cut thru and remove the varnish that prevents the part's from disassemble. Make's Life A LOT Easier. Just so you don't have to use the hammer or vice grip's. Just don't get water in the bearing's using DAWN Power Dissolver.

Just because they are pretty - Don't pick them up bare handed -THEY ARE HOT ! Use the Hot Dog Tong's.

COOK OUT DOOR's ONly !!!!!

Kinda Like the Fire Hand Test and Ultrasonic Cleaner's on moving part's that have bearing slide surface's or piston ring's or gem stone's in mounting's. They will Vibrate their way to death.

DON't DO THAT - It's HOT !

I'll measure mine next time. It doesn't seem to be temperature for mine but the amount of time you cook it.

Now the REALLY Cool Thingy : Is my One handed - portable battery powered automated part's washer and rinse tank using mineral spirit's

Hint' don't Lipo Power it - You'll have crap all over
