Furniture Care and Maintenance


Cure First
You have just finished applying a fine furniture finish. Treat gently until the paint or topcoat have fully cured. Allow 21 days for a water-based finish to cure before cleaning.


Regular Cleaning and Maintenance

  • Remove dust with a water-dampened cloth. Dust can build up over time and may scratch or dull finishes if not removed regularly. 
  • Remove fingerprints, cooking fumes and smoking residue with mild soap and water. These contaminants will not harm the finish, but they accumulate on surfaces and dull the original lustre. 
  • As with all fine furniture finishes, avoid using furniture polish, cleaners or dusting sprays that contain silicone, alcohol, ammonia and anything acidic. Exception: We have successfully cleaned with Clorox wipes.
  • Clean up water, alcohol and food spills in a timely manner and use placemats & coasters to protect the finish.
  • Future finishes or touch-ups may not adhere properly or perform as desired over a contaminated surface. Some contaminants, such as silicone, seep through finish into the wood and often cannot be removed.
  • Avoid excessive exposure to direct sunlight, high temperatures or high humidity. These can damage furniture and finishes.
