In this video Wally Makowsky from Coin Laundry Association shows you how to remove stains with strong solvents. Drop off laundry services use various strong solvents for cleaning stains but Wally Makowsky gives two recommendations. One is Laundry Wetspo which is an excellent general solvent. It can remove lipstick, paint, shoe polish, inks and regular food stains. The other recommendation is yellow go laundry which removes similar stains. Out of the two recommended methods, Laundry Wetspo is probably the most versatile solvent to remove stains.
