ToggleWhy Do Composite Decking Need Regular Cleaning? The Importance of Using Clean Composite Deck Cleaner
Although the surface of composite decking has a layer of composite layer, unlike solid wood decking that requires regular maintenance, long-term accumulation of dust, mold, and oil can cause the surface to oxidize, fade, or turn yellow. Excessive accumulation of dust reduces the anti slip layer on the surface, resulting in a decrease in anti slip performance. The growth of bacteria in gaps affects aesthetics and hygiene.

Step 1: Daily Basic Maintenance – Preventing Stains Before They Start
1. Daily simple cleaning
We only need to use soft bristled brooms, vacuum cleaners, or robots to clean fallen leaves, dust, and sharp debris every day to prevent scratching the composite deck.
2. Clean up spilled liquids
When there are colored or acidic or alkaline liquids such as coffee, red wine, etc. left on the composite decking, it is necessary to immediately wipe it with a damp cloth and absorb the excess water with a dry cloth.
3. Regularly move outdoor furniture
Every 5-6 months, adjust the position of tables and chairs to prevent prolonged gravity from causing local discoloration or water accumulation.
Step 2: Deep Cleaning – Choose the Best Clean Composite Deck Cleaner for Long-lasting Protection
Wrong approach:
Avoid using irritating products such as bleach. It is recommended to use the best clean composite deck cleaner, which can effectively clean without damaging the floor surface.
The correct cleaning method:
1. Use a neutral composite decking specific cleaning agent to prevent strong corrosive products from corroding the surface of the product.
2. Long handled soft bristled brushes or sponges can be used to avoid scratches on the surface caused by hard cleaning tools.
3. Use low-pressure water pipes or low-pressure water guns (pressure<1500 PSI).

How to carry out daily cleaning?
1.Prevent dust accumulation: Use a soft bristled broom or vacuum cleaner to clean surface dust every week.
2.Remove mild stains: Dip a wet towel into the clean composite deck cleaner and gently wipe the stained area.
3.Avoid scratching the floor: Avoid dragging heavy or hard objects. Suggest using rubber pads to protect the floor surface.
Step 3: Addressing Stubborn Stains – The Right Clean Composite Deck Cleaner for Each Type of Stain
Stain type treatment method
Mold spots/moss | Use a composite decking cleaning agent with anti mold formula to prevent mold and moss growth. Keep the surrounding area ventilated to keep the composite decking dry. |
Oil stains/barbecue sauce | Sprinkle baking soda or weak alkaline cleaner and let it sit for 15 minutes before thoroughly scrubbing, or use degreasing cleaner. |
Rust stains | Avoid direct contact between metal furniture and composite deckings. Rust stains can be thoroughly washed with oxalic acid or weakly acidic cleaning agents. |
Step 4: Seasonal Protective Measures – Keeping Your Composite Decking Clean Year-Round
Spring: Check the floor joints and remove any debris accumulated during winter.
Summer: To avoid prolonged exposure to sunlight, you can choose our ASA decking, which have antique characteristics and will not fade when exposed to sunlight. Or install a sunshade to prevent oxidation from occurring.
Rainy season: Regularly check the drainage system to prevent rainwater from accumulating and causing problems such as mold on the composite floor
Winter: Use plastic shovels when handling snow to avoid damage to the surface by iron shovels, and do not sprinkle salt snow.
