wash thoroughly first dark fabric dye will stain linens [SEP] the product works well and i continue to buy it but i completely forgot about brand new dark fabric tends to bleed and stain when wet my head was getting sweaty as i slept and some days i braid my hair damp with product and put the cap on letting it dry over night and woke ho to my light beige pillow case stained with the dyei took the new bonnet and washed it with dawn soap and the water turned deep bluish blacki should have known better but i just forgot i didn t even have these pillow cases for that lont and i love them update i ve washed this thing so many times and still the dye bleeds and leaves stains i have never had a piece of fabric do this after so many washes it s frustrating seeing these dye transfers on my linens
