I have a fish that I bought from a local shaper a few years back. I've noticed it's beginning to lose it's bright white color it had when I bought it, and it's starting to yellow a bit. I clean it, and put it in a board bag after every use. I've inspected the glassing, there doesn't appear to be any cracks in the glass, so I don't think it's taking on water. Is there anything I can do to stop the yellowing? The board is 2-3 years old, so I'm assuming it's probably normal. I usually don't keep boards this long, I go through boards quickly, so I'm not really used to the discoloration.
Let me clarify, it's not extremely yellow. Its just a very very light shade, most people probably wouldn't even notice it, but the board is no longer bright white.
