Choosing a neutral microcrystalline wax such as RENAISSANCE WAX eliminates problems that may be encountered with the use of acidic beeswax or harder waxes that may be impossible to safely apply at room temperature without harming the object. Any mild solvent like acetone or Stoddard's solvent can be used to remove the wax coating at any time. Avoid microcrystalline waxes that have extraneous components like silicon that may prove difficult to remove from the wood components. http://www.trapdoorcollector.com/restoration.html
