This inexpensive, multi-faceted stuff is well known to many in the guitar world as an excellent cleaner and polisher. Because it is free of wax, abrasives, silicones or acids, it can be used to spruce up even delicate vintage finishes. Use it on hardware, tuners and over pickguards. Polishing instructions are included on the bottle.
Luthiers will love how just a small portion darkens streaky fingerboards and bridges as it conditions the wood. It can be applied even after the board is fretted without danger of tarnishing the frets. One bottle is enough for dozens of fingerboards.
: It is also a great choice for the oil component of a French polish.
