White Stain: Zinc Oxide
Unfortunately, zinc oxide can sometimes stain darker fabrics. To help remove zinc oxide stains, we recommend soaking the garment overnight in regular white vinegar and then laundering it in the hottest water the fabric can handle. Air dry. If the stain is still visible after the garment has dried, repeat the soaking process and then launder again. It’s best to do this process before drying the garment in an electric dryer, which can set the stain. Note: If you are concerned about using vinegar and the colorfastness of your garment, try looking for an enzyme-based commercial stain remover made specifically for color fabrics.
Grease Stain: Olive Oil
Grease stains can be treated just like a stain from salad dressing! If the stain is mostly oil-based (rather than the white of zinc oxide), place baking soda on it and then let it sit for up to an hour before laundering. In addition to laundry soap, be sure to add a little dish soap as this will help to break up the oil, something that regular laundry detergents don’t always do. Wash your garment in the hottest water it can safely handle and then air dry. An electric dryer can set a stain, so be sure it’s no longer visible before using one.
Important! Using white vinegar and baking soda together can cause a bleaching reaction. We do not recommend using these stain removal techniques together unless the garment you’re treating is completely white
