Annihilates tough tannin stains and watermarks on all types of wood, decking, siding and fences; removes mill glaze. Penofin Pro-Tech Brightener re-establishes the Ph balance of your wood after stripping and cleaning and brightens gray weathered wood to bring back that mill-bright color.

Surface Preparation: Sweep the surface with a stiff broom or brush or use a power blower. Use Penofin Pro-Tech Stripper (Step #1) if needed to remove old stain and Penofin Pro-Tech Cleaner (Step #2) to prepare the area. Penofin Pro-Tech Brightener is most effective at temperatures where wood is not hot to the touch. Protect bordering metal surfaces. Dampen surrounding vegetation with water.

Application: Depending on desired strength, add 1-2 cups of Penofin Pro-Tech Brightener into one gallon of clean water and mix. Wet the surface with a garden hose and sprayer. Using a plastic pump up garden sprayer, apply the solution liberally. Wait 20-25 minutes and let it do the work for you. DO NOT ALLOW THE SOLUTION TO DRY ON THE SURFACE. Rinse thoroughly with water.

ALWAYS WEAR RUBBER GLOVES, EYE PROTECTION, AND SOLID SHOES WHEN APPLYING. SURFACE WILL BE SLIPPERY. DO NOT INHALE POWDER. DO NOT MIX IN A METAL CONTAINER. DO NOT STORE DILLUTED SOLUTION. DO NOT MIX WITH CHLORINE BLEACH OR OTHER CHEMICALS. HARMFUL OR FATAL IF SWALLOWED. CAN CAUSE EYE AND SKIN BURNS.

Average gallon coverage: Roughly 300-400 square feet depending on surface type. This container will make about 8 gallons of cleaner.

Cleanup and storage: Thoroughly rinse all equipment with water. Store any Penofin Pro-Tech Brightener in its original container in a dry place. Do not transfer to a metal container as it will cause a reaction. For disposal of unused product and empty containers, contact your local household refuse collection service.
