With today’s wide variety of colors and trims, it is important to test for colorfastness and cleanability before processing garments. A simple test can be done for colorfastness by wetting an unexposed area with volatile dry solvent and pressing it against a piece of blotter paper. (Cheese cloth or the corner of a white towel works just as well.) If color is seen on the blotter, then the item may lose color in drycleaning.
A similar test can be done on plastic beads, buttons, and trim to determine cleanability. Apply a few drops of volatile dry solvent. If the trim becomes sticky or tacky, then damage may occur to the trim during drycleaning. It is not recommended that testing be done with amyl acetate since this chemical is a plastic remover. Testing with amyl acetate may prevent you from cleaning items that could have been safely cleaned in a drycleaning solvent.
