Harold Baker, a product-development scientist at Clorox is known as “Dr. Laundry”. Here is some of his advice about stains:
Treat the stain as soon as possible.
Always pre-treat and pre-soak big stains before putting them in the laundry. You can use laundry additives and even dishwasher detergent.
Examine the stain after it has been through the washing cycle, but DO NOT put the garment in the dryer if at all uncertain the stain was removed. After you dry it, you’re going to set the stain into the fabric and make it harder to remove.
Club soda helps bubble up a stain out of the fabric. Bar soap actually helps set the stain.
Use cold water to remove stains with high dairy content.
