Teak furniture can be left outdoors uncovered all 12 months of the year, no matter where you live. If you choose to cover your teak furniture during winter, use a material that allows the wood to breathe. If you put your furniture away for the winter, do not store it in a heated room. Oiling teak is not a method that can be used to protect the wood and is generally not necessary. Since teak naturally produces its own oils, manufacturers typically do not recommend adding processed solvents into the mix. To restore weathered teak, first clean teak furniture with Teak Cleaner and then apply Golden Sealer to prevent re-graying.
