The finish on my kitchen chairs have become sticky. How do I clean it

white vinegar and water 50/50 and a dab of dish soap

wash with hot soapy water

Try using Goo Gone to remove the stickiness. Then go over with some Old English lemon oil or similar.

magic eraser, be careful if painted

Make a mixture of one part warm water and one part plain ammonia. Use it to clean the chairs, then wipe with a clean, damp cloth to remove any residue. The ammonia will clean and brighten the finish without damaging it.

I use murphy's oil soap and water. It does a great job on wood.

Karen gave you the right answer. After you wash with Murphy's oil soap, put Wilbert's lemon oil to preserve the wood, follow the directions on the bottle. Good Luck!
