Yellow Master is a new corrective treatment for all types of yellowing on carpet and upholstery.


Particularly effective for treating reactive yellowing associated with stain resistant nylon fibers. This yellowing can be caused by improper application of the stain resistant treatment or a reaction of moisture with the chemicals used in the backing or underlayment (adhesives, resins, BHT-Butylated Hydroxy Toluene, etc).


  • Yellow Master can also be used to correct cellulosic browning, water marks, tannin stains from coffee, tea, urine, beverages, and is excellent for stabilizing fugitive dyes.
  • Dyes can be stabilized with a pre or post cleaning treatment of Yellow Master.
  • Does not cause resoiling!

Ready to use pH is 1.75

To Correct Yellowing:
  Mix 4 scoops YellowMaster with one gallon water. Apply to fabric at a rate of 200 square feet per gallon and work in with a pile brush or rake. In severe cases, mix 8 scoops in one gallon of water. 
Residue-Free Rinsing:  For truck mount equipment mix 1.5 lb. (3 cups) of YellowMaster to 5 gallons of water. For Portables mix 1 scoop of YellowMaster with 5 gallons of water.
