Why does it stain so badly? Because of ingredients used in sun lotions, they commonly leave an oily looking stain behind. Sigh. The secret to removing sunscreen stains is to use a laundry detergent that expertly cuts through grease and oil, such as Persil® ProClean® Plus OXI Power Laundry . According to the makers of Persil laundry detergent , “a quick pre-treatment will help break up the oily stains, making it much easier for your washing machine to do its job effectively.” Always check labels for guidelines before washing garments.
Tip: Be sure to follow the fabric instructions and wash at the warmest temperature possible.
