There are certain rules that must be followed when cleaning clothes — whether you use perc, high-flashpoint hydrocarbons, GreenEarth, water or whatever.
First, the clothes need to be classified into lights and darks, heavyweights and lightweights, fragile or special-care items, degree of soil, and of course, bleeders. Once the loads are assembled, they should be checked to see if they need any type of pretreatment.
