I am looking to keep the whites white and the reds red. Its the whites I am concerned about. I have test tung oil and that darkens it way to much. Teak is a bit better and a butcher block finish is not to bad but its a bit soft if built to a shine. Ow I should mention food safe finish and by that I mean stamped on the side of the container or published food safe. I have tried a water base minwax poly I had around and I didn't like the dead feel it gave the wood. I may try another brand. I have tried a walnut past wax and its ok but I would rather have something I wouldn't worry about drying up or soaking in further over time and leaving dry spots that need to be retreated. I asked this question here due to the food safe part. Thanks.
