The Science Behind Guinea Pig Urine Stains

Guinea pig urine contains pigments called porphyrins, which can cause staining on clothes. Porphyrins are a type of protein that can be broken down by sunlight, heat, or chemicals, creating a reddish-brown color. The pigments in guinea pig urine are particularly concentrated and can be difficult to remove, making them more likely to cause staining. Additionally, urine can act as a catalyst for the oxidation of other substances in the fabric, which can result in discoloration. To prevent staining, it is important to clean up any urine promptly and to avoid exposing the affected clothing to sunlight or heat.

What You'll Need To Get Rid Of Guinea Pig Urine Stains

  • White vinegar
  • Baking soda
  • Enzyme laundry detergent
  • Hydrogen peroxide

Step By Step Process To Remove Guinea Pig Urine Stains

  1. Blot up as much of the urine as possible with a clean cloth or paper towel. Be sure to work from the outside of the stain in to prevent spreading.
  2. Mix a solution of equal parts white vinegar and water. Apply the solution to the stain and allow it to sit for at least 15 minutes.
  3. Sprinkle baking soda over the stain and gently rub it in. Allow the baking soda to sit on the stain for an additional 15 minutes.
  4. Apply a small amount of enzyme laundry detergent directly to the stain and work it in with a brush or your fingers. Allow the detergent to sit for at least 5 minutes.
  5. If the stain is still visible, mix a solution of 3% hydrogen peroxide and 1 tablespoon of baking soda. Apply the solution to the stain and allow it to sit for at least 15 minutes.
  6. Wash the garment as usual with warm water (60°C).
  7. Check the garment before drying to ensure that the stain has been completely removed.
Please note, some fabric may not be able to handle the hydrogen peroxide solution, it's best to check the fabric label or test a small portion of the fabric before using it. Also, always check the label of the garment before washing, as some fabrics may require special care or may not be suitable for certain cleaning methods.
