Use 6 oz. (3/4 cup) of DEFY Wood Cleaner powdered concentrate with each gallon of water. One gallon covers 100-200 sq. ft. depending on wood porosity.

STEP 1: MIX: Mix with water and stir thoroughly until powder is dissolved. Powder dissolves faster in warm water. Solution should be used within six hours of mixing.

STEP 2: APPLY: Horizontal Surfaces – Dampen surface with water before application. Apply DEFY Wood Cleaner solution with a pump sprayer, brush, or mop, working on small areas (20-30 sq. ft.) at a time. Vertical Surfaces – Dampen surface with water before application. Apply with a sprayer working on small areas at a time. Start at the bottom and work to the top.

STEP 3: BRUSH: Horizontal Surfaces – Let solution stand approximately 10-20 minutes, keeping area wet with additional DEFY Wood Cleaner solution. Thoroughly scrub with a stiff, short bristle broom or brush. Vertical Surfaces – Let stand approximately 10-20 minutes, keeping surfaces wet with additional solution. Thoroughly scrub with brush, working from bottom to top. DEFY Wood Cleaner will open wood pores and some raising of wood fibers may occur.

STEP 4: RINSE: Rinse thoroughly with water from garden hose or power washer (with 800-1200 psi) using lowest pressure that cleans without damaging the wood. Repeat steps 2-4 on next small area. Continually rinse cleaned area of vertical surfaces to avoid streaking as work progresses. Allow wood surfaces to visually dry before applying DEFY Wood Stains. Heavily weathered or soiled surfaces may require a second application.
