🪑 Effortless Trick to Remove Green Mildew from Patio Chairs

Green mildew usually appears on plastic, metal, or wood patio furniture after rain or humidity. Luckily, you don’t need scrubbing or harsh chemicals.

🧴 What You Need

• White vinegar or baking soda
• Water
• Spray bottle (optional)
• A hose or bucket of water

🏡 The Easy Method

1. Mix the Solution

• Vinegar method: Mix equal parts white vinegar and water
• Baking soda method: Dissolve 2–3 tablespoons of baking soda in 1 liter of water

2. Apply to Chairs

• Spray or pour the solution generously over mildew spots
• Let it sit for 10–15 minutes

3. Rinse

• Use a hose or a bucket of water to rinse off
• The mildew usually washes away without scrubbing

4. Optional: Sun-Dry

• Let chairs dry in the sun for a few hours—sunlight naturally prevents mildew from returning

💡 Extra Tips

• For stubborn mildew, repeat once more or let the solution sit 30 minutes
• Always test a small hidden area first, especially on painted or wooden furniture
• Regular application every few weeks keeps mildew from coming back

This is likely the “0-effort trick” your father-in-law uses—it’s cheap, natural, and works on almost any outdoor chair.
