I polish model airplane engine parts. I have always struggled with getting the buffing compound residue out of the nooks and crannies.

I just tried something new today, using very hot water, a soapy rag, and just rubbing the parts under the hot soapy rag until I got it clean and then rinsing it under hot water. It's an OK method, but not 100% effective. And it burns the crap outta my hands.

Does anyone know of an easy way, for a hobbyist to remove buffing compound? I did search the internet, and found industrial solutions, but those won't do me any good. I want to find something that will melt/dissolve/wash away the residue, or at least easily rub it away with a rag and some sort of cleaner but it must not dull down the shiny aluminum!

Thanks!
