Teak can be cleaned with a solution of laundry detergent, bleach and water. After cleaning the teak, you must apply a sealant to protect the wood. If the teak wood has developed a patina, you must first remove that before the wood can be cleaned.
- Remove the patina
Rub the wood with sandpaper until the patina is sanded off. Wear a face mask, safety goggles and work gloves when sanding. Sand in the direction of the wood grain to avoid damaging the look of the wood. Begin with a medium-grit sandpaper to remove the grey color, wipe with a tack cloth to remove wood residue, then follow through with a fine-grit sandpaper to smooth the surface. Wipe with the tack cloth a second time to remove all traces of wood dust.
- Clean the teak wood
Create a cleaning solution by mixing two parts laundry detergent to one part each bleach and water. Scrub the wood with a soft brush, using the cleaning solution. Rinse off the wood with clean water after scrubbing.
- Seal the teak
After cleaning, seal the teak wood with a teak sealant. The sealant protects the teak from exposure, preventing the patina from returning. After the sealant dries, you can clean the teak on a regular basis using only the cleaning solution and soft brush.
