I have a lovely oak table; most of its surface looks as pristine as the day I got it, e.g.:
Parts of the table surface are getting damaged -- the finish is wearing off and the pores of the grain are exposed and feel pitted to the touch, e.g.:
Any ideas why this is? It looks like the areas where this is happening are the areas that get the most sun (through a skylight, not directly overhead), but I haven't seen sun damage like this. Perhaps somebody else has?
I can rule out water damage or heavy use -- the table is lightly used and wear doesn't seem to be a factor as some of the most used parts look the most pristine.
Any suggestions for an intervention, short of or including refinishing?
