Abstract
Denim articles of clothing such as blue jeans, are conventionally treated with a permanganate. The permanganate is thereafter neutralized with a liquid composition containing peroxide, a sulfate and deionized water. The composition neutralized the permanganate, prevents the yellowing of the article and reduces the biological oxygen demand in plant effluent.
