Dawn dish soap in a 6 cup glass measuring cup under the facet.. in hot water..
really does test the fabric and can see right away if it will be a problem.. some just washes out.. and clear water then is what comes after the soap is gone..

I love Dawn and use it most of the time, but I think there is bleach in Dawn. I have had my dish clothes bleed forever and ever, even when I bleach them in the wash.
So Dawn might not be the best choice for washing fabric where you do not intend to bleach at all.
I use laundry detergent and mostly pre-wash. It depends on the source.
