RE: devarnishing glow engines ???????
The caustic grease removal substances will ruin your engine if left on the aluminum long term.
Notice the Cascade should only be on the engine for a short time in the instructions
The dawn can stay on about 45 min
You can also get a potpourri pot and put 50/50 antifreeze in it and you can soak the engine in the solution for a week. Do not boil
