cleaning solution to remove oil on an engine

[avee8tor13]

All,

What is the best cleaner that will not cause any damage like remove engine paint or cowling paint, when trying to clean a oily lycoming engine?

Thanks.

Mineral spirits works well.

Simple Green also has a formula originally developed for aircraft, now marketed for "Motorsports"

I will give this stuff a try. Again thanks.

Ditto mineral spirits. Cheap enough to use a suction sprayer and do a thorough job as often as needed. Dries fast.

I've used a spray can of foamy "Engine Brite" cleaner (automotive stuff) and rinsed off with a water hose. Made the engine look like new again. Just make sure not to get water inside the mags/alternator/starter, and let everything air-dry well before you attempt to start the engine.

Mineral spirits will make scat slimy. Every shop used to use it a lot. Not so much now. Evaporation rate is slow & it leaves a film/residue. That said, I still use it on a really juicy engine followed by hot water & degreasing detergent. For smaller or moderate oiliness try QD electronics cleaner aerosol. Almost instant evaporation, less mess.

LPS Precision Clean is what I've been using for years. It does a great job on greasy bellies, engines etc. I buy it in the gallon jugs and use diluted in a trigger sprayer. Its biodegradable and water-based.
Meets or exceeds these specs.
