What is a Bleach Alternative?

Try peroxide 1 c. to a washload

When they say bleach alternative they usually mean some bleach product that does not contain chlorine. Washing soda,peroxide as mentioned and color bleaches usually don't contain chlorine.

I use white vinegar to remove germs, bacteria and odor from clothes in the washing machine. About a cup per load. I buy it in a gallon jug at the grocery store.

You can also use borax, it's sold as 20 mule team borax where I live, in the detergent aisle.

Baking soda works too.
