Look for non-chlorine bleach at the market or try the following:
Add 1/2 cup baking soda to warm or hot water wash cycles.
Add 1/2 cup washing soda to warm or hot water wash cycles.
Add 1/2 cup lemon juice in the rinse cycle.
Add 1/2 cup of 3 percent hydrogen peroxide in the rinse cycle.
Tip: After clothes have spun dry in the washer, hang them to dry in the sun if possible. Sunshine is a natural bleach.
