How to keep your antique furniture looking fresh
WOOD: Many furniture pieces are coated with wax and may need professional maintenance. If you take care of it yourself, only polish twice a year with beeswax-based polish and a soft cloth. Don’t use spray polish because it may contaminate the surface and make it sticky. Keep furniture out of direct sunlight to avoid fading and make sure it is stored in a room-temperature environment.
MARQUETRY: Marquetry veneer is sensitive to climate changes, so check to see that it is still stable, especially in winter. If the veneer becomes loose, go to a professional to get the proper glues. Also consult a professional for polishing. Keep away from heat and direct sunlight.
SEATING: A professional should check your seating to make sure it is stable, which can involve new webbing on the bottom, strengthening of the wood, and reassembly using appropriate pegs and glue.
GILDING AND PAINT: Most pieces do not have their original gilding or painting. For restoration, consult a professional.
CAST METAL FEET (SABOTS) AND FURNITURE LEGS: Try to get a replacement for feet that will matches the original. Broken legs should be repaired by a professional.
