Key Takeaways

• Scrub gently with a stiff brush and eco-friendly cleaner to avoid wood damage
• Use oxygen bleach for mold/mildew instead of harsh chlorine bleach
• Rinse thoroughly to prevent residue buildup and discoloration
• Dry completely before reapplying sealant or replacing furniture

1. Clear and Prep the Deck

Remove all furniture, grills, and planters. Sweep away leaves and debris with a stiff-bristle broom. Cover nearby plants with plastic sheeting to protect them from cleaning solutions. Inspect for loose nails or splinters—hammer them down or sand rough spots. For optimal results, choose a cloudy day to prevent cleaners from drying too quickly.

2. Choose Your Cleaning Solution

Pick one of these effective options:

• Dish soap mix: 1 cup mild soap + 1 gallon warm water (safe for all wood types)
• Vinegar solution: 1 part white vinegar + 4 parts water (natural disinfectant)
• Oxygen bleach: Follow package instructions (best for mold/mildew)

Test any solution on a small hidden area first. Avoid chlorine bleach—it damages wood fibers.

3. Scrub Methodically

Work in 3×3 ft sections using a deck brush with nylon bristles. Always scrub along the wood grain to prevent scratches. For composite decks, use a softer brush. Focus on stained areas but avoid oversaturating the wood. Rinse each section immediately with a garden hose.

4. Treat Stubborn Stains

For specific stains:

5. Rinse and Dry

Use a gentle hose spray (no high-pressure nozzles) to remove all cleaner residue. Pooling water causes warping, so push standing water off with a squeegee. Let the deck dry 24-48 hours before sealing. For faster drying, sweep away puddles with a broom.

6. Maintain Regularly

Extend cleanliness with these habits:

• Sweep weekly to prevent dirt buildup
• Apply wood-safe sealant every 1-3 years
• Trim overhanging branches to reduce debris
