Here are some tips for treating stains on 100% cotton towels:

Act quickly

The sooner you treat a stain, the better chances of removal. Work on it the same day if possible.

Identify the stain

Know if it’s water-based, oil-based, or protein-based. This helps determine the best removal approach.

Pretreat the stain

Apply a stain remover or homemade solution (baking soda, detergent, vinegar) directly to the stain and let it dwell before washing.

Rub gently

Use a clean cloth or toothbrush to rub the treated stain, avoiding harsh scrubbing which can set some stains.

Use cold water

Warm to hot water can set stains further. Soak or wash in the coolest temperature safe for the fabric.

Try oxygen bleach

For stubborn stains, a bleach alternative containing oxiclean or hydrogen peroxide can help.

Sunlight

The heat of direct sunlight can help bleach out some ground-in stains after pretreatment.

Repeat as needed

You may need to re-treat the stain and rewash multiple times to fully remove it.

With patience and gentle stain removal, you can usually refresh cotton towels even after messy accidents. Don’t give up on a stain after just one try.
