I agree. I switched over to white towels and sheets years ago for myself (though I still have colors as well for personal use.) I have used Oxyclean with every wash for the last 15 or so years and have no problem with dingy whites, except when I’ve had to bleach them. I think repeated bleaching will start to yellow the whites for sure.
I had a string of room mates on and off over the years, and my colored towels were always showing up with bleach stains. I always just thought they (roommates) were careless with cleaning products, or there was a problem with my washer or the towels themselves… Thanks to this forum, years later I now know it was due to the acne products. Two of my roommates I know for certain used Proactive.
I bought some blue towels and sage towels early on thinking that it might be nice for guests in the same party to be able to have different colored towels to be able to distinguish one person’s towels from another in the bathroom. Dumb move. Blues were destroyed by the acne products, so everyone gets white towels again!
I used Rit brand to dye Thanks @Stagestop to get the towels back to blue. Worked like a champ. BUT, after several rounds of laundering with different techniques (add salt to the bath, e.g…) I still can’t get the blue dye to entirely set. They are still bleeding the dye! Any suggestions on this?
