we have a solid wood worktop in our kitchen, it's cherry wood I think, and the kitchen supplier said that every so often to sand it down and varnish it with danish oil. I did this last night but to be honest the results are disappointing. I hand sanded, put the oil on with a cloth and dried off the excess with another cloth (just like it says on the tin!) but the drier looking bits of the worktop still look a bit jaded. Has anyone any tips? Do I need a belt sander and get right down a few mm's?
