Hey Joan! I use peroxide in every load I wash! Peroxide is the main ingredient in Oxiclean, but it is far cheaper! Plus I feel good knowing that it is sanitizing my clothes as it is washing! Hope this helps!
I just use roughly a cup, unless it's heavily soiled I will use a little more!
Oxi-Clean works well.
You can also use 20 Mule Team Laundry Borax. And the Dollar Tree sells Awesome Oxi-clean generic brand in a round large jar.
