We have a 3 year old, 44 ft. power boat with exterior teak along the swimstep, and inside the cockpit. I have been using Simco, Natural oil, and it looks great for about 2 weeks, then it fades out. The attached pic is the same day after cleaning/oil, but just wanted to show the boats teak. It's not a high end boat compared to other 44 ft boats, so the teak thickness is marginal. I have read through some teak care articles on the web, but I wanted to run this by this Forum because I know a lot of folks on here deal with teak care, and on boats much more $ than mine. 1. No hard brushes to remove the Simco stain? A soft sponge, and the weak Oxylate or equivalent solution? 2. Considering this is not thick teak, is it ok if I lightly sand with a rotary sander? 3. Can I sand every couple years? 4. For cleaning it every couple months, what are people using? I have seen salt water mentioned a lot. Any other products out there? 5. If I follow the above protocol, will the teak have a nice light brown appearance, and not go grey/silver? 6. Am I reducing the life of the teak by not oiling? Thanks in advance.
