I gave you a tip HERE a few days ago about colorfasting material. I used the colorfast process on a new pair of dark jeans that I want to keep dark. My dear husband AKA Camera Man just had to film it! ☺ Maybe I should rename this post “don’t turn your husband’s underwear baby blue” since my new jeans would have done that, but you get the picture.
Not sure if your clothes are colorfast? If a label reads “wash separately,” “wash in cold water,” “hand wash,” “do not use detergent” or “turn inside out to launder” may indicate that the dyes in these items are not colorfast. To test, soak an inconspicuous corner of the material in a cup of warm water and a teaspoon of detergent for two to three minutes (less time for pre-treatment stain removers; follow instructions on the product label); then blot with a white paper towel. If the colors do not change, run or come off on the paper towel, and if the item is definitely washable.
