Keep and store wooden furniture in areas with well-maintained humidity. Wood can warp if it is exposed to too much humidity or frequent humidity changes. Protect your wood furniture by alternately using a humidifier and dehumidifier to regulate and maintain the humidity in the rooms where the furniture is being kept or used.
Avoid exposing your antique wooden furniture to moisture. This means keeping drink glasses, vases and other wet objects away from your wooden furniture. Limit mopping around the legs and bases of your antique furniture to limit moisture exposure.
Keep antique wood furniture out of direct sunlight and away from heat sources or high temperatures.
Only use cleaning products that are designed for safe use on wood. Cleaning products that are not safe for wood can lead to additional warping.
