We do not recommend using Zout® on any non-colorfast dyed fabrics and some fabrics that are lined. The lining may shrink if hand washed. Zout® Stain Remover is also not recommended for use on Cashmere, Leather or Silk.

Yes. It may require a second or third application or soaking in a strong solution of Zout® (1/8 cup in 1 – 1 1/2 gallons of water). Remember to test garments for colorfastness before using, even if previously laundered. Click on the Using Zout® tab.

We do not suggest using Zout® on upholstery or carpet because, as a super concentrated surfactant based product, it needs to rinse thoroughly. When not rinsed properly, soap will collect dirt. If Zout® has been used on upholstery or carpet, rinse until no soapsuds appear using a wet/dry vacuum or a carpet/upholstery cleaning machine.

Zout® will yellow slightly over time. Its efficiency, power and safety have not changed.

Yes, but only if the fabrics are colorfast and washable. Test for colorfastness by applying Zout® to an inconspicuous area for 5-10 minutes then rinse. If the color bleeds, the garment is not colorfast. Click on the Using Zout® tab.
