Status: offline 		Hi all- Recently learned of using warm antifreeze to clean up engines that have been sitting for decades, and boy- sure works well! Does anyone know if warm anitfreeze will harm the old paint used by some manufacturers? I hope not, but really have no parts to experiment with. Any experience soaking an engine like this?

Status: offline 		I would NOT put that particular engine in the crockpot 'o antifreeze! You would end up with an all silver/natural metal engine...

I also know (found out the hard way ) that it will remove the black from the black case redheads...

It doesn't damage anodizing though unless you get it too hot.

Edit: I just wanted to add something...
While I have used this treatment on dozens of engines, I have only done a few engines that had some anodized parts, and they came out OK.
A friend did an old Webra Diesel with the red fins, and he got the antifreeze rather hot...steaming...and the anodizing came out a faded pink.

If you can't stick your finger in the solution and keep it there for a few seconds without it burning you, then it's probably too hot.

Status: offline 		Thank you Max and Proptop! I was wondering about anodized parts as well, didn't think it would do to much but glad to know there's a limit to how much heat they can take. Need to put a dimmer switch on my little pot as it doesn't have heat settings. Looks like I'll be using regular old 5% fuel to clean up some of these old engines. Thanks for the warnings! Jeff
