Purchased table at resale store and cant get rid of old cooking smells

I Used an online tip which worked: Wipe down smelly table with VODKA. Yes, sounds weird, but it works. Just use the cheapest vodka you can buy, wipe piece down. The vodka dries quickly and doesn't have an odor itself.

I think this will help.

I'd leave it out in the sun for a few days. Cleaning it like you have, has cleaned the surface, but the wood has been permeated by the cooking odors. I'd probably clean it again with a vinegar wash first, using as much water as I felt I could.

Sal has my idea. I'd wipe it down with straight vinegar, every nook, cranny and crack, top and bottom being quite liberal, and place it in the shade for several days.

If after this time the grunge smell remains, wrap and totally seal the whole thing in plastic with about 5-10 pounds of charcoal brickettes and wadded up newspapers.

thanks for the vodka tip...it is alcohol after all

I suggest you sitting it out in the sun for the day. Some oil smells are nearly impossible to get rid of.

Also, Murphy's Wood Cleaner migit do the trick as well.
