Simply use a lint-free dampened cloth with a touch of gentle wood-specific cleaner and wipe in the same direction as the wood grain. Doing so on a regular basis will keep your Transformer Dining Set™ looking as clean as the day it was delivered to your home. This furniture line is scratch, heat, stain, and liquid resistant. Due to the nature of the solid wood materials, we highly recommend taking the necessary precautions to keep your dining table looking brand new for many years to come, such as using protective accessories like tablecloths, placemats, coasters, and hot plates to shield your Transformer Table™. Make sure to store your different Transformer Table™ components in the same living space as much as possible, and always keep them in a climate-controlled area. Optionally, you can occasionally use solid wood polishing oil to restore the shine of your hardwood furniture pieces. In the case of an accidental scuff, we do include a bottle of touch-up stain with each Transformer Table™ order so you have a perfect match on hand.
