I have a couple of engines that need cleaned up on the inside & out side. What would work the best? Would rubbing alcohol or acetone work? Thanks

If you have old fuel on hand that would get rid of all of the gunk inside and out. I use denatured alcohol and just soak the engine in it then dry and oil.

There are a number of commercial engine cleaners out on the market such as demon clean and z-best engine cleaner. If these are not available at your hobby shop, look in any model airplane magazine for their ads and get some sent to you. They work very well and won't damage the engine like homemade stuff sometimes does.

Good Luck,

General cleaning of an engine buried in the flield (due to sudden impact..) I use the "waste" fuel from my gallon jugs. (the last 2 to 3 oz of each gallon is usually contamnated enough that I don't want to use it to run the engine)

Cleaning of an engine that's been coated with brown stains.. soak overnight in antifreeze (mix per bottle instructions, get stuff rated for aluminum block engines.) It helps to heat the antifreeze... and many people will get an old crock pot from a garage sale and dedicate it to engine cleaning. (never use something that has had antifreeze in it for food!)

I use the crock pot method. I remove the carb and don't soak it. Head and back-cover come off and give it about 8 hours on low heat. It is advised that high heat will discolor the aluminum. 50/50 mix works great. Rinse with water and any crud left on engine will easily come off with a toothbrush. Then I blow it out with air, and coat everything with Marvel Mystery oil. I ignored the warnings and tried this with an Enya. It turned a mottled grey. But it was sure a clean grey.[img]i/expressions/face-icon-small-happy.gif[/img]

My dad just got a parts washer, will that work?

That baked on castor is really tough to clean. Be sure to wear rubber gloves when using the parts washer. The solvent can penetrate through the skin and cause nerve damage. This is common in old timer mechanics.

FHHuber, I like the sound of the crock pot and antifreeze. I may have to pick-up an old crock pot and try it, thanks.

Again, try the commercial stuff! it works in 15 minutes and is sooooooo easy its not worth the time with this other crock.
