Test ASTM D 426b Stain Removal
Title Charlie's Soap tested on a Wide Variety of Soils
Test fabrics (bleached 100% cotton) were washed with Charlie's Soap Laundry Powder and dried before staining. The fabrics were then stained and allowed to sit for 30 minutes. The stained fabrics were then pre-sprayed with Charlie's Soap All Purpose Cleaner and agitated till all parts of the stains were exposed and allowed to sit for another 30 minutes. The fabrics were then rewashed with Charlie's Soap Laundry Powder and air dried. Results were determined by light reflectance difference before staining and after washing the second time.
