The Science Behind Cockroach Stains

Cockroaches can stain clothes because they excrete a pigment called ommochrome, which is found in their body fluids. This pigment can transfer onto fabrics and other surfaces, leaving behind a yellowish or brownish stain. The stain is difficult to remove because the ommochrome is water-insoluble, meaning it does not dissolve in water, and thus it does not come out in a normal wash. The pigments are also resistant to most common solvents and cleaning agents.

What You'll Need To Get Rid Of Cockroach Stains

  • Dish soap
  • Hydrogen peroxide
  • Baking soda
  • White vinegar
  • Enzymatic cleaner (such as Nature's Miracle or Folex)
  • Laundry detergent

Step By Step Process To Remove Cockroach Stains

  1. Mix a solution of equal parts dish soap and hydrogen peroxide. Apply the solution to the stain and gently rub it in.
  2. Sprinkle baking soda on top of the stain and let it sit for 30 minutes to an hour.
  3. Using a clean white cloth, gently blot the stain to remove as much of the solution as possible.
  4. In a separate bowl, mix together a solution of 1 part white vinegar and 1 part water. Using a clean white cloth, gently blot the stain with the vinegar solution.
  5. Apply an enzymatic cleaner specifically designed for protein-based stains such as cockroach stains and follow the manufacturer's instructions.
  6. Wash the garment in a washing machine on the hottest water setting that is safe for the fabric with laundry detergent and let it air dry.
It is also important to note that if the cockroach stain is not removed after the above steps, it may be permanent and may require professional cleaning. Additionally, it is important to make sure that the garment is not dried in a dryer before checking if the stain has been completely removed, as heat can set the stain making it more difficult to remove.
