Was thinking of the tedius process of varnishing teh cabin sole but got a pretty good tip. Instead, gently sand with 400 grit sandpaper just to remove any ground-in debree. Next wipe clean with a mixture of 1/4 vinegar to 3/4 water and let dry.
The product, Restor-a-Finish is recommended becauuse you can use it to put on top of finishes. Simply wipe on, I used cheese cloth and let dry. Apply a second coat, wiping off excess and let dry again. When all done, should restore a bit of lustre to the sole.
Just something to do on a rainy weekend when you want to get your mind off of things, mainly boats headed south for the winter 😉
