The Secret to Removing Mustard and Curry Stains

There’s a reason mustard and curry stains are some of the toughest to get out! They are considered a pigment stain – a naturally occurring color that is not water soluble and therefore cannot be removed with normal cleaning.

CAUTION: The process used to remove pigment stains is the most aggressive stain removal process and has the great possibility of removing the dyes used to color the carpet fibers during the manufacturing process. There is a great risk of removing or bleaching the color of the carpet fibers.

Tools needed: 

  • Prochem Urine Rescue
  • Eyedropper or pipette
  • Terrycloth towel
  • Steam Iron (Caution: This process can damage your iron’s finish)


  1. Agitate the spot with a brush or a bone scraper and vacuum to remove as much of the spot in its dry form.
  2. Apply Urine Rescue to the stained fibers only using an eye dropper or a pipette. Do not apply with a sprayer.
  3. Dip the terrycloth towel in water and wring out as much water as possible.
  4. Fold the towel in half and place onto the area where the paste has been applied.
  5. Using a iron set on “Dry” and heat set to medium heat, place the iron on top of the wet towel.
  6. Wait 15 seconds then remove the iron and lift the towel to check the process.
  7. If the stain is still visible, repeat steps 3-6.
  8. When the stain is no longer visible, clean the stained areas to remove all residue.

CAUTION:  Repeated attempts using this process can bleach the carpet!
