How to Remove Blue Windex Stains from Carpet


Lawrence asked: How do I remove a Windex stain from our car’s carpet? My wife spilled a Windex bottle on the back floor of our car on the carpet. It looks like a permanent water stain. I would like to get rid of the stain. Imagine my surprise to see Windex being recommended to remove stains on carpet!

Windex is indeed a good stain remover for carpeting. However, it is not recommended that colored Windex be used as this can lead to another stain – blue. If this has occurred on your carpet, follow these steps to remove the unwanted coloring.

You Will Need:

  • Oxiclean
  • Mild detergent
  • Water
  • Bucket
  • Sponge
  • Soft cloths
  • Heavy object
  • Wet Vac (optional)

Steps to Remove the Blue Stain:


  1. Begin by moistening the area with a small amount of water.
  2. Apply a small amount of OxiClean to the surface area and allow it to set for several minutes.
  3. Blot the stain with a clean cloth to remove the OxiClean.
  4. Rinse by blotting the area with a soft cloth moistened with water.
  5. Next, mix a small amount of mild detergent with warm water in the bucket.
  6. Use a sponge to gently blot the sudsy water onto the stained area.
  7. Rinse thoroughly as before by blotting with a clean cloth/sponge moistened with clean water.
  8. Ensure that all of the soap is removed or the residue will attract dirt and cause the area to become soiled more quickly.
  9. Once the area is clean and rinsed, it will be necessary to remove as much water as possible to avoid a watermark.
  10. Press clean, dry cloths on the area to absorb as much as possible.
  11. Lay a couple layers of cloths over the area and apply a heavy object to the top of the cloths. The pressure from the heavy object will help to absorb the remaining water.
  12. If there is a wet vac available, it will be helpful to vacuum the excess water out of the carpet.
  13. After several hours, remove the heavy object and cloths and allow the area to air dry completely.
  14. Vacuum the area with a regular vacuum to restore the texture of the carpeting.

Additional Tips and Ideas:

  • If the OxiClean does not remove the stain, stain removers such as Spray ‘n Wash can also be applied.
  • Do not apply bleach to any areas where there is ammonia. Mixing these two liquids results in hazardous fumes.
  • For severe dye stains, refer to the removal methods found on How to Remove Hair Dye from Carpet.

    We followed exactly with Oxiclean and this did not remove any blue coloring. We did not use Windex to clean, but the bottle leaked out when I left it on a leather recliner, which also has a permanent mark. Any suggestions for the chair?
    Thank you.

    My contractor spilled a bottle of Windex with ammonia an my newly installed carpet and now I have a blue stain that has dried in. Is there any remedy that will not leave a permanent reminder?

  4. Melanie says:

    If Oxyclean and mild detergent don’t work to remove the stain, try the methods in the article How to Remove a Hair Dye Stain from Carpet. If those methods don’t work, use a commercial carpet stain remover. Spot shot is one that works particularly well on dye stains. For that, follow the instructions in the article How to Remove Dye from Carpet.
