I Recently Encountered the Same Phenomenon
Recently refinished the interior of my 1980 Hunter 36, and I noticed the same color situation you have querried about. Each situation is different, so I won't presume the below is the answer for you, but a recount might be of use:While working on my project, as with you, I wondered if the teak and its finish had naturally aged to the reddish color. But eventually, I came to the conclusion that the interior teak and teak veneer plywood was given a cherry color at the factory. Probably because the different panels of veneer and pieces of solid teak trim weren't consistant in natural color. Or "cherry" color might have been the rage at the time? Anyway, apart from the stain color, to me, it looked like most of the interior finish coats on the trim, paneling, drawers and doors were tung/linseed/teak type oil just rubbed on through the years by PO's. I used a strong solution of industrial "purple" janitorial cleaner (Home Depot) on these items which worked better at removing the oil finish (and years of accumulated dirt/grime) than paint removers. I quickly learned not to spray this solution on, which resulted in splash marks where the spray hit first, but instead to apply it to the wiping cloth and rub it on. The solution disvolved the dirt and the oils, but left the underlying stain intact. I followed with several few wipe downs with plain water. I re-finished only with a minwax polyurethane rubbing oil. The final result is good to my eye. Color looks good and I can now see the wood grain. Before the job, all the interior wood looked like it had been covered with too many coats of semi transparent and dingy stain. There were a few cabinet doors on my that ended up more quite a bit more like teak's natural yellow/orange'ish brown rather then cherry. I used a mahogany colored stain to restore the cherry color ... close enough. But most of the boat's wood color ended up just fine with only the Minwax polyurethance rub.regards,rardi
