Household-strength bleach contains just two essential components, hypochlorite and hydroxide, and the hypochlorite is well-known to damage soft fabrics. In this invention is discovered a third component, the concentration ratio which is the concentration of hypochlorite over the concentration of hydroxide in the bleach solution. Although considered impossible, hypochlorite bleach can be made fabric gentle by elegantly balancing the concentrations of hypochlorite and hydroxide, requiring no ingredients commonly added to mitigate the damaging effect of hypochlorite. It's all in the ratio (or the reciprocal). By adding hydroxide to a solution of given hypochlorite salt concentration, the bleach fabric protection progressively improves for ratio values below 12.5:1, reaching maximum protection at a ratio value about 2:1. By comparison, the ratio value is >30:1 for fabric-damaging common regular bleach. Regular hypochlorite bleach that eats up cotton can be converted to cotton-gentle hypochlorite bleach having the same cleaning properties.
A method for preparing a bleach cleaning composition for cleaning a stain from a soft fabric article and by which method the damaging effect of a metallic salt of hypochlorous acid solution on the soft fabric article can be reduced progressively to a minimum, said method comprising,
