It works pretty well, and would probably work even better in a heated washer. At least it's affordable.Equally affordably is citris cleaner sold at Home Depot for about $9.00 a gallon. I have been using it as a de-greaser on my bicycle and automotive part for at least six years with decent results. The Simple Green just didn't work as well for me.
