Removing green deposits from garden furniture: the right approach for each material

A green haze on your garden furniture requires an approach that suits both the material and the finish. Therefore, first check whether you are treating teak, plastic, a coated frame, or a stone tabletop. Choose the appropriate cleaner, test on an inconspicuous spot, and follow the instructions on the bottle label. Below, you can read how to carefully coordinate cleaning and any subsequent protection.

Hard materials

Removing green deposits from aluminium, ceramic & stone

For aluminum, plastic, ceramic, and stone, first check the furniture manufacturer's recommendations and the finish. A coating or top layer helps determine which cleaner is suitable. Test the Multi Surface Cleaner on an inconspicuous area and follow the current label. The instructions provided for the 750 ml Multi Surface Cleaner state a three-minute contact time; do not adopt a longer wait time from a different product.

Clean with a soft sponge or appropriate cloth and rinse thoroughly with clean water. Do not use a pressure washer on garden furniture. If dirt remains, follow the instructions on the cleaner for a repeat treatment. Afterward, only protect the completely dry surface with a protector suitable for the material.

Wood & teak

Removing green deposits from wood & teak

For teak, use the specific wood maintenance routine. Wet the wood thoroughly and apply Teak Cleaner according to the current label. The provided instructions state a three-minute soaking time. Clean with a suitable scrubbing pad in the direction of the grain and rinse thoroughly with clean water. Do not use a high-pressure cleaner: it can damage the wood.

Allow the wood to dry completely before applying a protective treatment. Choose a color protector if you wish to treat the wood color, or transparent Teak Shield for water- and dirt-repellent stain protection. Follow the specific drying times for the chosen bottles. A protector does not guarantee that green deposits will never return.

Frequently asked questions about green deposits

Why are my garden furniture turning green?+

Green deposits mainly form on surfaces that remain damp for long periods. Check your furniture regularly, remove loose dirt, and follow the maintenance routine for the material and finish. A protective treatment is no guarantee against new deposits.

May I use a pressure washer to remove green deposits?+

For these maintenance routines, use a soft sponge, suitable pad or cloth and clean water. A pressure washer can damage wood and coatings. Always check the furniture manufacturer's maintenance advice.

How do I remove green deposits from teak?+

Wet the teak, use Teak Cleaner according to the current label, and clean with a suitable pad in the direction of the grain. The provided cleaner instructions specify a three-minute soaking time. Rinse well and allow to dry completely before applying an appropriate follow-up treatment.

How do I prevent green algae from coming back?+

Remove dirt regularly and keep track of maintenance. After cleaning, you may choose to apply a suitable protector, but keep in mind that deposits can form again. Follow the furniture advice and ensure that wet parts are allowed to dry.

Do vinegar or bleach work against green deposits on garden furniture?+

Do not automatically apply a tip for a patio or other material to your garden furniture. Check the furniture advice and use the prescribed cleaner. Do not mix cleaning agents on your own initiative; follow the product label.
