How to clean your decking?

Conventional method

1. Firstly, use a broom to remove any excess leaves and debris from the surface. You should also use a hard bristle brush or scraper to remove any accumulations of moss, leaves, or algae. This will leave the surface clear to begin cleaning.
2. Prepare a bucket of hot soapy water or grab a bottle of composite decking cleaner.
3. Apply the hot soapy water or cleaner to the decking. Once applied use a hard-bristle brush to scrub the surface of the decking. Any surface debris will start to lift off.
4. Leave the hot soapy water or cleaning product on the surface to stand for several minutes before rinsing the boards. Ensure all cleaning fluid, soap, and debris have been successfully removed from the boards before leaving to dry.

Mineral Deposits

Mineral deposits appear on the deck surface when regular cleaning of COOWIN wpc does not occur.

These deposits appear because of rain mixing with runoff from roofs, soil/dirt, pathways, etc. When evaporated on the deck, it creates a haze on the deck that can be washed away if seen within a certain time period. If overtime this haze is not cleaned it can build up and create layers that are more difficult to clean. The following cleaners we recommend using to wash off the mineral deposits:

• Household/Laundry Detergent
• Vinegar

Note: Do not use any other cleaner that is not recommended because it could potentially damage the deck’s surface. Also, never use the cleaners together when cleaning, only use one of the choices to clean.

NEVER MIX CLEANERS.

Materials/Cleaners

1. Towel
2. Bucket
3. Water
4. Steel Wool / Rigid Brush or Broom
5. Dishwashing Gloves

Note: In certain environments, mineral deposits can appear more rapidly and may become serious. To keep mineral deposits from reappearing COOWIN.

WPC recommends cleaning the boards at least once every 2 months.

In this guide, we will show you how to take care of mineral deposits that build upon the deck surface.

Note: Always wear gloves when dealing with cleaners.

Cleaning the Area

You can see the boards that have the mineral deposit on the top of the surface. We will be using a mixture of water and vinegar to clean off the boards.

1. First we will need to make a 50/50 mixture of vinegar/water. We will first start by pouring water into a bucket.

2. Then we will add the same amount of vinegar to that bucket.

3. After we have made the mixture and thoroughly mixed it together, we will apply the mixture onto the boards that are affected by the mineral deposits.

4. After applying the mixture leave it on for at least 5 minutes to let the mixture get deep into the mineral deposit - it makes cleaning much easier.

5. After allowing the mixture to sit for at least 5 minutes, use the steel wool and begin to scrub in the direction of the grain. The strength of the scrubbing will depend on how thick the mineral deposit is - usually, medium-strength scrubbing is sufficient.

6. After scrubbing for about 1-2 minutes take water and rinse the area and dry the area with a towel to see the result.

Note: It might take multiple times scrubbing the board in order to get the mineral deposit off the surface.

Also, quicker results may be seen if you continuously scrub while adding the mixture to the affected area.

7. After drying, the affected boards should look brand new. You can see the difference between the area cleaned versus the area not cleaned.
