The large areas of loss to the varnish on the main lids were replaced using a dried version of the varnish and building this area back up to tie in with the original surface. These small, dried pieces of varnish were adhered with a dissolved version. Losses to the carved elements on the legs and piano sides were re-carved in lime wood and smaller areas were replaced with a special putty used for gilded surfaces. These replacements were re-gilded with gold leaf and toned to match the original gilding.

The other areas of gilding were cleaned with a conservation grade mild soap to remove the excess dirt. Any losses to the painted decoration were retouched with acrylic paints. A final layer of varnish was added to the lids to protect and bring together the new varnish with the old. The metal mounts were cleaned with a conservation grade metal cleaner.
