It is also safe on all washable synthetic and permanent press fabrics, except spandex. Sodium hypochlorite bleach is safe for most non-colored washable fabrics. Be sure the solution penetrates the fabric. Let stand for 1 minute and blot dry with a paper towel. If there is no color change, the article can be safely bleached.
Oxygen bleaches are available in both a dry and liquid form.
All dry oxygen bleaches contain inorganic peroxygen compounds, such as sodium perborate tetrahydrate and sodium percarbonate. Liquid oxygen bleaches contain hydrogen peroxide, which supplies the oxidizing agent directly. The hydrogen peroxide reacts with the soil and organic materials in the wash to either decolorize or break them up. Hot water accelerates the bleaching action. As water temperature decreases below 130 degrees F, exposure time must be increased.
