Safe and Cheap? Wow, you aren't asking for much. This question got me looking at different Material Safety Data Sheets (MSDS) and I was surprised nothing is safe anymore, sigh. Here's the MSDS sheet for Procter and Gamble laundry soap for goodness sake. Here's a random purple degreaser. My guess is that nothing that will cut oil residue is totally ...


This isn't answering your question but may answer your need (removing stubborn engine grime). Soften the grime by rubbing engine oil into it. The engine oil doesn't have to be new; used oil works just as well. Once the grime is softened, it becomes much easier to pull it off with a less intense solvent like brake cleaner.

Standard automotive brake fluid (DOT 3,4 and 5.1) are made from polyethylene glycol (PEG). PEG is soluble in water, methanol, ethanol, acetonitrile, benzene, and dichloromethane, and is insoluble in diethyl ether and hexane. A long way of saying it will clean up with soap and water. DOT 5 brake fluid is diorgano polysiloxane (Silicone). It is not soluble ...
