I picked up a 200 y/o buffet, and its quite beautiful. However many areas of the wood are very dry looking. There is also a few water stains. What can I use to bring back the luster w/o stripping the wood? I dont want a wood cleaner as I know that will strip the wood and remove any of the old stains that are giving the buffet its character.

The wood is oak.

I also picked up a 100 y/o eastlake dresser which just needs some light cleaning, can I use the same wood polish for both? I dont know what the wood is of the dresser.

I really know nothing about wood and needs some help, thanks!!
