Just to make you feel better about Renaissance Wax... it is not a natural wax, but created in a lab of microcrystalline fossil-origin products. This means there will be no acid created through hydrolysis or oxidation such as in beeswax or other natural waxes. It is used by: UK: British Museum, Victoria & Albert Museum. Royal Armories (Tower of London , London & Leeds, National Army Museum, Imperial War Museum, the Wallace Collection, H.M. the Queen's Royal Armorer (at Marlborough House), the Guards Museum (Wellington Barracks), the Gurkha Museum (Winchester), the Military Museums at Aldershot, Royal Green Jackets Regimental Museum, the Gunsmith at Chatham Historic Dockyard (Kent), the Johnny Armstrong Gallery, and Museum of Border Arms & Armor (Scotland), National Museum of Antiquities of Scotland. Belgium: Musee Royal de l'Armee et d'Histoire Militaire-Brussels. USA: Gunsmith at Colonial Williamsburg, The Smithsonian, Metropolitan Museum of Art, Academy of Art-Honolulu, Texarcana College-Bladesmithing & Metallurgy, Rockfeller Restorations, Colonial Williamsburg Conservatory, Abraham Lincoln Residence, Vicksburg Military Park and Museum, Henry Food Museum, Academy of Arts, Metropolitan Museum of Art, NRA Museum, Rockefeller Restorations, Frank Lloyd Wright Foundation, Hilton Hotels, BYU Museum of Art, National Ornamental Metals Museum, and more. I think if these experts feel comfortable using Rennaissance Wax, then you can too.
