How to Clean Teak Outdoor Furniture: A Complete Care Guide

Teak outdoor furniture is prized for its rich color, tight grain, and natural resistance to rot and insects. Left outside, it develops a silvery-gray patina that many homeowners love. Whether you prefer the weathered look or the warm honey tone of fresh teak, a simple care routine will keep your chairs, tables, and benches strong and good-looking for years.

Why teak needs special care

Teak contains natural oils and silica that make it far more durable than most outdoor woods. Those oils repel water and resist pests, but sun, rain, and dirt gradually draw them to the surface. Routine cleaning restores the wood without stripping these protective compounds. Harsh chemicals, steel wool, or high-pressure washing can do more harm than good.

How to clean teak outdoor furniture

For regular maintenance, you only need water, mild soap, and a soft brush. Plan to clean teak furniture once or twice a season, or whenever you notice dirt, bird droppings, or mildew spots.

1. 1

   Rinse with water

   Start by hosing down the teak with clean water. This removes loose dirt, pollen, and debris from the surface and grain. Avoid pressure washers — the concentrated stream can gouge the wood and strip its natural oils.

2. 2

   Scrub with a mild solution

   Mix a few drops of gentle dish soap or a pH-neutral teak cleaner into a bucket of warm water. Dip a soft-bristle brush or sponge into the solution and scrub along the grain. Work in small sections so the soap does not dry on the surface.

3. 3

   Rinse and dry completely

   Rinse the piece thoroughly with a garden hose until the water runs clear. Wipe away excess water with a clean towel and let the furniture air-dry for at least 24 hours before sanding or oiling. Trapped moisture is the main cause of mildew.

How to remove mildew and stains

For black mildew spots, make a paste of equal parts baking soda and water. Gently rub it onto the affected area with a soft brush, let it sit for 10 minutes, then rinse. For stubborn stains, a dedicated teak brightener can restore the wood without bleach. Always test any new product on the underside of a table or chair first.

How to sand teak furniture

Sanding is only needed when the surface feels rough or you want to remove the gray patina before oiling. Use 120-grit sandpaper and work with the grain, not against it. Follow with 220-grit for a smoother finish. A light hand is enough — aggressive sanding removes more wood than necessary and shortens the furniture's life.

After sanding, wipe the surface with a damp cloth to remove dust, then let it dry fully before applying oil or sealer.

How to oil teak outdoor furniture

Oiling is optional. Teak does not need oil to resist rot, but oiling preserves the warm golden-brown color. If you like the silver-gray patina, you can skip this step entirely.

Choose a teak-specific oil or a marine-grade sealer. Apply a thin, even coat with a lint-free cloth or brush, working with the grain. Let the oil penetrate for 15 to 30 minutes, then wipe away any excess. A second coat can be applied after 24 hours if the wood still looks dry.

Year-round teak maintenance tips

• Cover or store cushions separately to prevent mildew underneath.
• Use breathable furniture covers during long periods of non-use.
• Avoid placing hot pots directly on teak tables — use trivets.
• Tighten bolts and inspect joints once a year.
• Lift furniture when moving it; dragging can split the legs.
