Sunscreen Oil Stains

So I assume you tried the pretreat method I recommended on the 800 #? My guess is that you may need to pretreat the spot/area using either liquid dishwasher (Dawn) or detergent to solubilize the oils (apply, rub in, wait 3-5 minutes), and then wash immediately in the warmest water recommended on the care label using detergent and 3/4 cup Clorox® Regular Bleach₂ (for whites) or for colors Clorox2® Stain Fighter and Color Booster, our oxygen bleach based on hydrogen peroxide. If the stain is grease/oil-based, you’ll want to avoid water when treating the stain. The presoaking in OxiClean® probably fails since it does not have enough surfactants needed to dissolve the grease/oil portion and the small amount in the product becomes diluted when used as presoak. I believe the pretreat recommended above might be better.
