Every outdoor design is subject to the elements. Although resistant and low-maintenance, deck boards and their finishes take a beating and it’s not always clear what maintenance products to use on the various coverings to remove dirt while ensuring their durability and waterproofing. Here are the green tips for cleaning your deck. No need to spend all your money on a Karcher or other high pressure cleaner! Grab your broom and follow these tips to clean all surfaces. No need for bleach!
To clean your wood deck
Even if the composite wood or natural exotic wood used is rot-proof, it is often necessary to clean it with a broom and warm water containing Marseille soap or black soap. You can also degrease the wood by diluting percarbonate of soda with hot water (about 30g/L). Apply the resulting solution with a brush to the wood deck boards. Leave it on for about 20 minutes and then rinse with water.

Dirty wood deck to clean
Avoid using an acidic cleaning product (white vinegar, lemon juice…) for the longevity of this outdoor deck. A little multi-purpose baking soda or black soap diluted in water will clean the paving. To prevent stains and mildew on the deck floor, dilute 2 tablespoons of baking soda per liter of warm water, then vigorously scrub each deck tile with a scrub brush. To remove moss and dirt between outdoor deck tiles, you can add basil essential oil to your bucket of soapy water.
For a tiled deck or natural stone deck
Scrub your deck vigorously with soda crystals, black soap or Marseille soap added to water. If the joints are dirty, mix one part baking soda to one part warm water, possibly lemon juice for whiteness and scrub!
