Once cleaned, just cover with anhydrous lanolin. It's fairly cheap and stays put. It can be applied under water and is totally Eco friendly. If you use your boat you will have to reapply. Not sure how long it will last, but it's fairly cheap and it only takes a little. It is grease made from sheep's wool. Just warm up the container to make it easier to apply. Side benefit is that it will make your hands nice and soft.
Example of someone else that uses it.
Example of where to buy.
