I've used mineral spirits in parts washers with good results. From my reading water based solvents seem to work well only if you heat them up to 150-180 degrees. Hydrocarbon based stuff usually works well at room temps. Most machine shops I've worked for use the hydrocarbon based stuff.Jan 6, 2009
Are water based parts washers any good?
Water-Based An aqueous or water based parts washer is the safe and effective alternative to using harmful solvent parts cleaning. Solvent parts washers clean parts with petroleum based contaminants that are toxic, flammable and polluting.Oct 23, 2018
