Extending Life of old Ship Teak Deck
I have a boat with a 46-year old teak deck in acceptable condition. The planks are glued to the hull and after replacing one, I realize that a refit is a huge prohibitively expensive task. Now I'm wondering if there are stains, which can significantly prolong the wood's life.
Unfortunately there is a lot of conflicting information out there. Everybody has an opinion, but most focus on appearance, price and workload rather than longevity of the material.
One common school of thought is that the natural oils already protect the wood and only light cleaning is necessary. Technically I would agree, except that these oils can't last forever. A logical conclusion would be to replenish them, but since available "teak oil" is different than actual teak oil, I expect at least some products to be of the snake variant.
Can you guys help with some information or recommendation please?
