Protein and Bio Stains: Cotton

Your Stain Guide Solution

Protein stains are biological and come from human and animal substances, such as egg yolk, milk, perspiration, vomit, and bodily fluids. While even the sight of these stains is enough to send many into a panic, never fear.

Apply product(s): Apply Stain Solution directly to the affected area.

Work the stain: Work the solution into the fabric using your our Stain Brush.

Pour water on the stain: For added cleaning power, pour boiling water from a kettle onto the affected area. (Pour from a safe height so the water won't splash on you.) The force of the pouring water helps to do the work. You can also use hot water from a faucet set to its highest water pressure output. (When treating bloodstains, always use cold water.)

Soak up to 30 minutes: Soak the item in a basin filled with hot water.

Reapply or repeat as needed: If the stain is not completely gone, repeat this process until satisfied.

For urine stains and odors: Soak the item in a basin of hot water mixed with 1/4 cup of white vinegar.

Launder the item: Wash according to our instructions.
