After a pretreatment for the tough stains. All laundry shirts and jeans are placed into the washer for a series of washing and extracting, using an unscented and dye free enzyme soap. We also have two separate additives for especially tough stains, an additive for grease stains leftover from food and another for working on your car grease statins. We offer starch or no starch on both shirts and jeans and add our starch in the final rinse cycle to prevent "starch spots".
