One common procedure is to scour goods for 30-45 minutes in a bath at 180°F(82°C) containing:

 

  • 1-1.5% owg                                          Orconol CHSA Conc™
  • .07-0.1 oz/gal(0.5-.75 g/L)          Tetrasodium Pyrophosphate(TSPP)

Drop Bath and rinse goods well.

 

Another procedure is to run goods for 30 minutes in a bath at 180°F(82°C) containing 1-2% owg Anionic Wetting Agent.
