Part A – Cleaner

  1. Always follow manufacturer’s instructions on packaging for best results.
  2. Remove dirt and debris with a broom and garden hose.
  3. Mix 1/3 cup Wood Cleaner (Part A) with 1 gallon of hot water.  Mix thoroughly and let the powder fully dissolve before using.
  4. Apply liberally to wood surface using a garden sprayer, mop, brush, pump sprayer, etc.  Wait 10-15 minutes, while maintaining a wet surface (a light spray nozzle on a garden hose works well).  Scrub with a stiff broom or scrub brush.
  5. Rinse thoroughly with clean water using a spray nozzle and garden hose, or the lightest setting (no more than 1200 psi) on a power washer and let dry.
  6. Repeat steps 1-5 if needed.

Part B – Brightener

  1. For use after cleaning wood with Part A.
  2. Mix 1/3 cup Wood Brightener (Part B) with 1 gallon of hot water.  Mix thoroughly and let the powder fully dissolve before using.
  3. Apply Messmer’s Brightener (Part B) in the same manner to clean rinsed wood with a generous and even coat.  No need to scrub or brush this time.
  4. Allow 30 minutes for color restoration.
  5. Wash off thoroughly with a garden hose.
  6. It is important to do BOTH parts, as Part B re-balances the pH in the wood.
