I have tried all sorts of homemade detergent recipes, and none of them get my husbands nasty work clothes clean. He comes home with all sorts of smelly, greasy stains (coolant, transmission fluid, brake fluid, oil, diesel, bondo, etc)... and the only detergent that seems to make them come out less smelly and spotty is Tide. Anyone know of anything I can use to "boost" the power of my homemade detergent? Or should I just bite the bullet and buy a jug of Tide to use only on his clothes? Thanks!
