What concentration of hydrogen peroxide can damage cotton and linen fibers?

Hydrogen peroxide is commonly used in cleaning and bleaching due to its oxidizing properties, but it can also be damaging to certain textiles such as cotton and linen fibers if used in high concentrations. A concentration stronger than 3% is particularly harmful to these fabrics, as it can lead to fiber deterioration, weakening, and discoloration.

At higher concentrations, hydrogen peroxide not only acts as a bleaching agent but also breaks down the cellulose structure in cotton and similar natural fibers, which can lead to irreversible damage. The damage becomes more pronounced with increased exposure to these higher concentrations, which makes it essential for cleaning technicians to exercise caution in their applications.

While lower concentrations, such as those below 3%, may be safer for use on cotton and linen, consulting with fabric care guidelines and conducting spot tests can prevent damage. Therefore, it is crucial for upholstery and fabric cleaning professionals to understand the risks associated with various concentrations of hydrogen peroxide, particularly when dealing with delicate textiles.
