The #1 Guide to Decking Cleaning

Keeping your decking in top condition is key to maintaining its lifespan and appearance.

Whether you have uPVC, composite, or timber decking, regular cleaning prevents dirt build-up, mould, and algae, ensuring a safe and attractive outdoor space.

This guide will show you the best methods for decking cleaning, with a focus on uPVC decking, along with tips on how to clean decking boards efficiently.

Why Regular Decking Cleaning is Essential

Decking is constantly exposed to the weather, which can lead to grime, mould, and slippery algae forming over time.

Regular cleaning:

• Enhances the deck’s appearance
• Prevents mould and mildew growth
• Reduces the risk of slips and falls
• Extends the lifespan of your decking

For uPVC decking, in particular, routine cleaning ensures that the material remains stain-free and maintains its vibrant colour.

How to Clean Decking Boards: A Step-by-Step Guide

Cleaning your decking doesn’t have to be a time-consuming task.

By using the right techniques and products, you can keep it looking great with minimal effort.

Below are the best methods for different types of decking.

Cleaning uPVC Decking

uPVC decking is one of the easiest types to maintain due to its weather-resistant and low-maintenance properties.

Here’s the best way to clean it:

• Remove Loose Debris: Sweep the surface with a soft brush to remove leaves, dust, and dirt.
• Use a Mild Cleaning Solution: Mix warm water with a mild detergent or use specially formulated decking cleaning products like Mayfield’s Decking Wash Bombs for an effortless deep clean.
• Scrub Gently: Use a soft-bristled brush or mop to apply the solution, paying extra attention to any stubborn stains.
• Rinse Thoroughly: Use a garden hose or a bucket of clean water to rinse off the cleaning solution.
• Let it Dry: Allow the decking to dry naturally before use.

Cleaning Timber Decking

Wooden decking requires a more careful approach to prevent damage:

• Sweep the Deck: Clear away any dirt and debris to prevent scratching the surface
• Apply a Deck Cleaner: Use a specialist timber decking cleaner to remove stains and algae
• Scrub the Surface: A stiff brush will help lift dirt from the wood grain
• Rinse and Dry: Use a hose to wash away the cleaner and let the deck dry fully before sealing or oiling.

Cleaning Composite Decking

Composite decking combines plastic and wood fibres, making it more resistant to mould and stains than timber.

Follower these steps:

1. Remove leaves and debris with a broom
2. Warm water and mild soap are usually enough for outline cleaning
3. A soft brush or sponge will help lift dirt without damaging the surface
4. Hose down the decking and let it air dry

Best Products for Decking Cleaning

Choosing the right cleaning products ensures effective results without harming your decking material.

Here are some recommendations:

• Mild Soap and Water: Ideal for regular maintenance of all decking types
• Specialist Deck Cleaners: Designed to remove stains, mould, and algae
• Pressure Washer (Low Setting): Suitable for stubborn dirt but should be used cautiously on timber
• Mayfield Decking Wash Bombs: A powerful yet gentle cleaning solution specifically designed for uPVC decking, making the cleaning process hassle-free

How to Prevent Decking from Getting Dirty

Preventative care reduces the frequency of deep cleaning. Here’s how:

1. Sweep Regularly: Removing debris prevents dirt build-up and mould growth
2. Use Outdoor Mats: Placing mats near entrances minimises dirt transfer
3. Apply a Protective Sealant: For timber decking, this helps repel moisture and stains
4. Trim Nearby Plants: Reducing shade and damp areas discourages algae formation

FAQs

How often should I clean my decking?
For the best results, you should clean your decking at least twice a year—once in spring and once in autumn. However, if your decking is in a shaded or damp area, more frequent cleaning may be necessary to prevent mould and algae build-up.

Can I use a pressure washer on my decking?
Yes, but with caution. For uPVC and composite decking, use a low-pressure setting to avoid damage. For timber decking, a pressure washer should be used sparingly, as excessive pressure can strip away protective coatings and damage the wood.

What is the best way to remove algae from decking?
A specialist decking cleaner or a mix of water and white vinegar can help remove algae. Scrub the affected area with a soft brush and rinse thoroughly. For uPVC decking, Mayfield Decking Wash Bombs offer an easy and effective solution.

Do I need to seal my decking after cleaning?
Sealing is only necessary for timber decking to protect against moisture and UV damage. uPVC and composite decking do not require sealing, making them lower-maintenance options.

What should I avoid when cleaning decking?
Avoid using harsh chemicals like bleach, which can damage the decking surface. Also, refrain from using abrasive scrubbing tools, which may scratch the material. Stick to mild cleaning solutions and soft brushes for the best results.
