Mango Crafts recommends Celtic Wood Care as the best and only treatment for waxed, varnished, or previously-sealed wood. This old craftsman’s formula comes in a white bottle and is a liquid wax-based product. It nourishes the timber whilst also restoring it by cleaning and polishing the surface, thus maintaining and enlivening the character and grain of the table.
Celtic Wood Care also helps to prevent shrinkage. By nourishing the timber, it ensures the flexibility of the timber fibers, allowing the timber to continuously move to adapt through the seasonal fluctuations in house temperatures.
Nothing will prevent shrinkage, however, if the house is too warm. The dry heat of modern house heating systems can vary drastically. Natural timbers do not react well to houses with temperatures over 21c, especially dry air heating systems.
