Boost Sour


Boost Sour is a concentrated laundry sour designed to reduce iron discoloration from the water supply while prolonging fabric life. Boost Sour neutralizes residual alkalinity from laundry detergents and builders, thus preventing dulling iron residues from building up on fabrics. Neutralizing the alkalinity and gently fluorinating the linens improves the fabrics’ look, feel, and life.

Product Description

Boost Sour (SOUR) is an acidic laundry rinse that neutralizes residual alkalinity (pH) left behind from laundry detergents, builders, and water in commercial laundry washing machines. Our product prevents iron residues from building up and discoloring fabrics. Boost Sour also prolongs the life of linens, facilitates ironing, and keeps your linens white and bright.

We care about our consumers and the environment, which is why Boost Sour does not contain nonylphenol ethoxylates (NPEs). Thus, there are fewer regulatory restrictions associated with our concentrated acidic laundry rinse compared to similar NPE-containing products.
