BHT and Sulfanated Phenol Browning Removal from Carpet

These two products were added to carpet backing to increase the life of the carpeting. Most BHT came from rebound carpet cushion. The carpet mills stopped using BHT around the late 1980s. Yellowing from these two products appears as very bright yellow, like a legal pad or a canary.

Recommendation:

  1. Mist on Citric Acid diluted at 8 tablespoons per gallon of water. Only mist onto top of carpet fiber. Agitate slightly with a Grandi Groom.
  2. Let dry thoroughly.
  3. Vacuum aggressively when dry.

Warning: Always test materials for colorfastness, follow label directions, and never mix products unless specified in the label directions. Each situation reacts differently and results may vary.
