Parts Washer cleaner

I've tried most all of the environmentally friendly stuff....because let's face it, IF there's something out there that works well, it would have to be better for the planet. BUT, all I have found is stuff that works well for a very short period......it get's "loaded up" if you will with all of the grease that comes off stuff and looses it's effectiveness. I use straight mineral spirits now.....not the low odor stuff. Just good old make you have two headed babies mineral spirits.
