Remove green deposits from wood with the following steps!
Removing green deposits from wood isn't difficult! Wood is often used on patios, including accessories and structures. But most patios also feature a lot of wooden garden furniture. With that in mind, we've created a handy step-by-step plan to make your wooden garden furniture shine again!
Step 1: Wet the wooden garden furniture
It's best to clean your garden furniture after a rainy day. Is it sunny? Then start by wetting your wooden garden furniture. This can easily be done with a garden hose or a bucket of water. Make sure all surfaces are thoroughly wet so the cleaning agent can work properly.
Step 2: Clean the wooden outdoor furniture
Mix a cup of baking soda or table salt with a bucket of lukewarm water. Apply the mixture to the wet furniture. Use a soft brush or sponge to gently remove the green residue. Scrub along the grain to avoid damaging the wood.
Step 3: Rinse it off
Rinse the furniture thoroughly with clean water to remove all cleaning agent residue. Be careful not to leave any soap residue, as this can damage the wood. Let the teak garden furniture dry thoroughly afterward!
Step 4: Apply a protective agent
Once the garden furniture has dried, you can apply a protective layer to it. This can be done with a teak shield or a teak protector. Apply it with a soft cloth. The shield is a transparent protective layer, while the protector is colored. Both maintenance products help protect the wood from moisture and new green growth. It's best not to use a pressure washer to clean wooden garden furniture!
