Bleach in its many forms is a proven stain fighter (or at least a stain lightener). The type of bleach used should be matched with the cleaning task at hand, however. Following is a list of bleaches from mildest to harshest and the best uses for each:

• Sunlight: This one might surprise you. It was one way your grandmother got white clothing and bedding so bright. Unlike many chemicals, it’s non-toxic. It can dry out and kill mildew in short order.

• Ammonia: A strong alkaline degreaser that should not be used on mirrors, marble, leather, soft plastics or aluminum surfaces.

• Mild acids: Lemon juice and white vinegar are mild bleaches.

• Oxygenated bleach: “All-fabric” bleach is an example of an oxygenated bleach containing hydrogen peroxide-related ingredients for use on colorfast clothing.

• Hydrogen peroxide: This pharmacy antiseptic - properly diluted - is safe for a wide range of fabrics and surfaces.

• Chlorine bleach: Sodium hypochlorite can be effective on laundry stains and those on other household surfaces, but it’s best to dilute it for all uses. Straight bleach is a highly corrosive liquid that can damage metal, fiberglass and a number of other household surfaces. Likewise, avoid breathing its vapors and protect skin and eyes from undiluted bleach. Always follow label directions carefully.

Ammonia, peroxide, color removers and chlorine bleach are all poisonous if swallowed, so they should be stored out of the reach of children. Don’t mix chlorine bleach with ammonia or any other cleaning solution that might contain ammonia – the combination can form a toxic gas.
