Pressure wash decking to remove algae

Decking adds beauty and functionality to outdoor spaces, but over time, it can develop algae, making it slippery and unattractive. Removing algae effectively and preventing its return will keep your deck safe and looking its best. Here’s a step-by-step guide to pressure wash decking to remove algae

Gather Your Cleaning Supplies

To clean algae from your decking, you will need:

• A stiff-bristle brush or deck scrubber
• A bucket of warm water
• Mild dish soap or specialised deck cleaner
• White vinegar or baking soda (for natural cleaning)
• Pressure wash decking with suitable equipment
• Protective gloves and safety goggles

Remove Surface Debris

Start by sweeping away leaves, dirt, and other debris from your deck. This will make the cleaning process more effective and prevent additional buildup.

Apply a Cleaning Solution

There are several effective cleaning solutions for removing algae:

• Soapy Water: Mix warm water with mild dish soap and scrub the deck thoroughly.
• Vinegar Solution: Combine equal parts white vinegar and water, apply to algae-covered areas, and let sit for 15 minutes before scrubbing.
• Baking Soda Paste: Mix baking soda with a small amount of water to create a paste, apply it to affected areas, scrub, and rinse.
• Commercial Deck Cleaners: Follow the manufacturer’s instructions for best results.

Scrub and Rinse

Using a stiff-bristle brush, pressure wash decking in the direction of the wood grain to loosen algae. Rinse thoroughly with clean water using a hose or pressure washer on a low setting.

Prevent Future Algae Growth

To keep algae from returning, consider these preventative measures:

• Improve Drainage: Ensure your deck has proper drainage to prevent water pooling.
• Increase Sunlight Exposure: Trim nearby trees and bushes to allow more sunlight, which helps keep algae at bay.
• Use a Deck Sealant: Applying a water-resistant sealant can prevent moisture buildup.
• Regular Cleaning: Sweep and wash your deck regularly to remove dirt and prevent algae growth.
