The frequency of which you maintain the work piece depends upon the usage, the type of wood and the type of finish used.
Regular dusting, preferably with a static duster or feather type cleaner. Using a normal cloth can scratch the finish.
Try re-buffing the project, if a shine cannot be achieved, then apply a light coat of wax, allow the wax to dry, then rebuff the project to restore its full glory.
If the work piece looks dull, especially if using Tongue Oil on Oak, then an application of wax maybe necessary after 2 – 3 months, and again after 6 months. This because the oil is still drying and being absorbed into the wood. After the 6 month period you should not have to worry about this phenomena, and routine maintenance should be sufficient.
Use aerosol furniture polish. Most of these polishes contain silicone, which is detrimental to the natural waxes used.
use detergents or water – if the piece becomes sticky or dried on dirt is present, then use a damp cloth to wipe away the dirt, allow it to dry and then reapply a the wax.
Do not place the item to close to a fire or heater – the heat will damage the wood and melt/soften the wax.
Try to keep real wooden projects out of strong direct sunlight.
