There are a few things you need to consider. What is compatible with the
pump and other materials in that system, what you intend to clean,
flammability, and how you will get rid of the waste which may be considered
hazardous waste. There are a number of petroleum and water based solvents
available. Most water based solutions work best heated. These solvents have
worked well for me over the years.

The one with lanoline is a bit easier on the hands.
