Avenger Formulas FLASH AF Instant Mold and Mildew Stain Remover, 1 gallon (Pack of 1), Rapidly Eliminates Stains from Most Indoor and Outdoor Surfaces

Flash-AF Stain Remover is an aggressive stain remover designed to clean stains from mold & mildew within seconds of application. The proprietary formula instantly targets deeply embedded stains and sticks to the substrate, garnering better results than with other products, which saves you time and labor. HOW TO USE: 1) Substrate should be clear of dirt and grime prior to application of Flash AF Stain Remover. 2) Shake vigorously for 30 seconds before opening product. Apply undiluted. 3) Coverage is 200-400 sq.ft. per gallon depending on the type of material it is being applied to. 4) Contain and remove all excess overspray and drippings to avoid discoloration of unintended material (e.g. fabric and carpets). 5) Rinse any sensitive materials (ie. aluminum, steel, nylon) with water post application to avoid deterioration. 6) Multiple applications may be required on heavily stained material.
