If OxiOut Algae and Mold Remover dries on the surface prior to rinsing can I apply more product?
Yes, mist the effected area with water and additional OxiOut Algae and Mold Remover solution; let it work on the surface as directed then rinse thoroughly before the surface dries. Never allow OxiOut to dry on your surface, as a white, powdery residue will result. (In order to avoid flash drying, do not apply to hot surfaces like roof, concrete, wood decks, etc.
