No. Clorox Disinfecting Bleach should always be diluted with water first before allowing it to contact any soft or hard surface. Don’t give in to the temptation to apply full strength bleach to stains — in time the area that was exposed to undiluted bleach could end up with a hole. Instead, if you have a stain on a bleach-safe comforter you can always pretreat with a bleach and water solution made with ¼ cup bleach added to ¾ cup water. Apply the bleach and water solution to the stain and then immediately machine wash the item using detergent and ⅓ cup Clorox Disinfecting Bleach.
