What is the worst stain??
We see several different types of stains, but food stains especially ones with alot of grease are the toughest. Often, part of the problem is that the stain occurs on Monday and laundry is done on Saturday. By that time, it has had lots of time to sit and soak in to the fabric. Pretreat as soon as possible!!!! It may not be perfect, but it will help.
