Re: refinishing companionway boards
The discoloration isn't natural and by the glint off the lower board in your snap, it would appear that there is still elements of the earlier finish embedded in the grain of the wood. More scraping/sanding is indicated. Once you've finished that, use a two part teak cleaner to clean and "bleach" (with the second part "brightener") the wood. That will most likely restore the natural coloring. If not, however, you can use an oxalic acid solution on the more heavily discolored areas although you'll need to repeat the two part cleaner treatment afterward.
Once you've finished I suggest you not use "spar varnish" to refinish the wood. It doesn't last very long and weather's poorly. A better alternative is a Cetol treatment: Two coats of "Natural Teak" followed by three coats of "Gloss" to seal the wood and provide a good UV shield. Thereafter, at roughly 6 month intervals, a quick wash-down/rub with a 3M "Scrubby" Pad and a further coat of Gloss will keep the boards looking good. BTDT...
