When choosing a deck cleaner for stained decks, consider these factors:
- Type of Stain: Identify the stain (algae, mildew, dirt, tannin) to select a cleaner with appropriate ingredients.
- Deck Material: Ensure the cleaner is safe for your deck's wood type (cedar, redwood, pressure-treated pine).
- Ingredients: Opt for oxygen bleach (sodium percarbonate) for general cleaning, or specific solutions for tougher stains. Avoid harsh chemicals like chlorine bleach, which can damage wood.
Recommended Deck Cleaners for Stained Decks
- Oxygen Bleach Cleaners: Effective for general dirt, algae, and mildew. These are generally safe for most wood types and won't remove stain if used correctly.
- Oxalic Acid Cleaners: Ideal for removing tannin stains (dark stains from wood tannins). Use with caution, as it can lighten the wood.
- Proprietary Deck Cleaners: Many brands offer deck cleaners specifically formulated for stained decks. Read labels carefully and test in an inconspicuous area first.
Application Tips:
- Always follow the manufacturer's instructions.
- Wet the deck before applying the cleaner.
- Use a soft-bristled brush to scrub gently.
- Rinse thoroughly with water.
- Test in an inconspicuous area before applying to the entire deck.
Safety Precautions:
- Wear gloves and eye protection.
- Protect plants and surrounding areas.
- Ensure proper ventilation.
