I am at a place here in MI that is using something I've never heard of, but thought I'd share as it may be something someone is interested in. It is called Mrs. Stewarts Liquid Bluing. It evidently works better than clorox and doesn't make things yellow over time. And if something is yellow you might be surprised at the results! It is a concentrate and this owner just mixes it with her regular liquid detergent for whites. If you have heard of it, please share what works for you as I am still in the learning process.
