For those wondering the differences from lee valley/ others
Some info from another forum
“Renaissance Wax is a brand based on conservation wax mixtures developed by the British Museum in the 1950s. The formula is fairly straightforward; BASF's "Wax A", a polyethylene microcrystalline wax, Cosmolloid 80 H, a non-polyethylene microcrystalline wax, and a hydrocarbon solvent with a high flash point (type-3 white spirits). Some document restorers and other conservators may prefer polyethylene-free mixtures which are more easily cleaned, removed or reversed, but inclusion of polyethylene won't adversely affect tools and finishes for woodworking. While each brand is likely to have its own tweaks and differences, any brand based on pH neutral microcrystalline waxes, whether poly or sans, should be suitable.
I mix my own variants, preferring harder versions for metals and stones, softer for certain leathers, vellums or parchments. For library, museum and other restoration and conservational uses, paying more for Renaissance brand may make sense, but for day-to-day woodworking and tool care, cheaper is absolutely fine, so buy the Lee Valley. Either way, the stuff lasts so long and goes so far even the high-priced spread amortizes as thinly as it coats.“
