How to remove a Blood Stain from Cotton.


It is extremely important to evaluate the stain, color and material before proceeding. Some of the products that we will be using can cause color loss and material damage.

Test First: in a hidden area apply the product to a white towel and dab in a hidden area of the garment. Check the towel to see if any color has transferred over. If the color is sensitive or the material is delicate you must modify your technique.


Blood is a protein and can be easily removed if the stain is fresh. An aged blood stain, on the other hand, can be permanent. Never apply heat to a blood stain as this will cause it to set the stain.


Several products will be recommended starting with the mildest or safest product for the color and material of the garment.


Liquid Dish Washing Soap.


Enzyme Stain Remover.

General Liquid Stain Remover.

Most general stain removers are alkaline and will strip color.


Household Ammonia.

Of all the products recommended this is the most dangerous for your health and the garment. Use with caution.

Ammonia is high in alkalinity and will strip soft color instantly.


Regardless of the product you used it is important to dry clean or wash the entire garment after completing the stain removal process. Any of these products residues will age and oxidize over time and cause yellowing or discoloration.


Remember to always evaluated color and material. Test for color bleeding in a hidden area of the garment before proceeding with the stain removal. Using a white towel apply a small amount of the solution onto the towel and dab a hidden area of the garment. If color transfers to the towel, re-evaluate the use of the product and technique. Rubbing and scrubbing will cause excess color lost.


Seek professional help if necessary. If you have a good relationship with your green dry cleaners they will be more than happy to help you with stain removal questions.
