Wooden Table - Wax, Oil?

I would scrub it with a rag and some Murphy's Oil soap. That way it would be clean down to the bottom of the grains and it wouldn't hurt the wood. Then let it dry completely after rinsing well. Once it's done you can sand it a bit if it needs it. Wipe it off with a tack cloth then put a finish on it.

If it is not something you'd want to eat off of then it has to be cleaned, sanded and refinished. Then it will be a piece of furniture you can be proud of.

I'd try Liquid Gold (Wood Cleaner & Preservative) on it.

You definitely do not want to use soap and water on it - that might ruin the finish.
You probably want to get a protecting pad to put on it.

I have custom made tables for my dining and breakfast area. Per the recommendation of the store Amish Furniture Company), I use Guardian wood cleaner and Guardian polish. Both can be purchased at most better furniture stores as well as Bed Bath and Beyond. They are about $6 a can.

I would not put soap and water on it at all.

I also agree if it is not finished and ready for daily use, get a custom pad to fit on it to protect it until you can get it finished.

Good luck.

I love Howard Feed-N-Wax which is a great wipe on, wipe off product.
