Dust your wood table often. Tiny dust particles may appear harmless, but significant accumulation can damage the wood’s finish. Dust using a gentle, lint-free cloth at least once a week (cheesecloth, a cotton diaper, or a cut-up old t-shirt all work wonderfully). Avoid specialist dust polishes since they include silicone’s that can sink into the grain of the wood and permanently harm it. Instead, lightly dampen a cloth or use a microfiber cloth that will cling to dust particles on its own
Use vinegar and oil to get water rings out of your wooden table. If you have watermark rings on your tables from wet glasses, combine equal parts vinegar and olive oil and apply it to the ring with a gentle cloth, moving with the grain of the wood. After that, use another clean, soft cloth.
Keep it away from the radiator. Place a wood dining table away from radiators and heat registers. Temperature variations might cause warping or cracking in the wood.
Watch humidity levels. Try to keep humidity levels in your house between 40 and 45% for everything woodwork, from flooring to trim, dining tables to other furnishings. Any lower might cause the wood to shatter, while any higher could cause swelling. Most of us will do this by running a humidifier in the winter and an air conditioner or dehumidifier in the summer.
Make your wood table shine. As previously said, it is preferable to avoid using silicone products. Alternatively, use a strong castor oil wax to polish. Apply the wax using one of those soft, lint-free cloths and polish with the other. It will take some effort, but happily, this activity only has to be completed around twice a year.
