How Do I Clean Composite Decking?

Cleaning composite decking is by far easier than wood. While wood decking requires sealing, scrubbing, painting, or spraying, composite decking requires a simple cleaning to remove stains or dirt. 

How you clean your decking depends on the kinds of stains you want to remove from the surface. A deck stained with dust is easier to clean than one stained with oil or grease. Also, removing mold from a decking surface is hard work because you have to scrub and rinse the surface. 

Removing Dirt and Debris

You can sweep the top with a broom to remove dirt and debris from your decking surface. Ensure you sweep the holes between the deck boards to remove all traces of dust and debris. You can use any of the composite decking cleaners to wash the surface of your deck to keep it spotless. 

Removing Concrete or Cement

When working with concrete or mortar, you should cover your deck as much as possible to prevent particles from getting on the surface. If cement gets to your decking surface and dries, it stains the surface, which is very difficult to remove. The recommended cleaner to use is the Sakrete Concrete Dissolver. 

Removing Hard Water Stains

Hard water contains a high amount of silica, calcium and lime. When the water dries, it leaves deposits behind, forming spots that distort your deck’s appearance. You can clean the deposits by washing the surface with white vinegar and warm water. Also, you can use a deck brightener product to clean hard water stains. 

Remove Tannins 

To make your deck free of tannin, remove debris with a broom or hose and ensure the top is clean. After, you should wash your decking surface with water and soap. You can use a deck brightener that contains oxalic acid to remove tannins. 

Removing Ice and Snow

You don’t have to wash the surface of your decking with soap to remove snow. All you need is a shovel with a plastic edge that you can use to push snow and ice off your decking surface. 

Removing Oil and Grease

Cleaning your composite decking surface when it is stained with oil or grease requires using composite decking cleaners. You can select a deck cleaner and apply it on the surface. After, spray water and scrub the surface with a brush until you have removed all the oil and grease stains from the surface. Rinse your deck surface to remove all traces of soap. 

Removing Mold and Mildew

If you don’t maintain your composite decking, pollens or rotten leaves can cause mold and mildew growth on the surface. To remove mold and mildew, the recommended composite decking cleaner to use is the Mold Armour deck and fence wash.
