Removing Stains from White Clothes
For white, bleachable items (like cotton, polyester, and poly/cotton blends—always avoid bleaching wool, silk, mohair, leather and spandex!), first pretreat the stains with Clorox® Bleach Pen Gel. Apply a little of the gel directly to the stain and gently rub it in using the soft scrubber tip. Wash the item immediately in the hottest water recommended on the garment care label using detergent and ½ cup Clorox® Regular-Bleach. Let the item(s) air dry and then check for success.
If a stained item has color, or if the item has any spandex (check the care label!) then first pretreat with Clorox2® Stain Remover and Color Booster. Apply a little Clorox2® liquid directly to the stain and gently rub it in. Wait 5-10 minutes, and then wash in the hottest water recommended on the item’s care label using detergent and more Clorox2®.
The residual oil scenario makes the most sense if the stains appeared only on the front of the shirts and pants where you might have had a food stain. Often these stains seem to come out with washing but the oil gets left behind. I hope this information is useful—let me know if you have any other questions, and thanks for writing!
