I bought this to clean engine parts from several projects I’m working on and couldn’t be happier with it. It does take a while to heat up but I found if I use warm tap water to start with it heats faster. A couple suggestions from YouTube helped a lot. Use simple green and Dawn dish soap to clean greasy parts. Smaller parts can be put in a glass jar to save on solution. Put solution in the jar and water in the tank. As I keep the machine on a table I added a thin hose to the outlet valve to empty the tank into a bucket. Last thing, put a foam weather strip on the lid to reduce the vibration noise.
