My bottle of Fret Doctor arrived! I discovered a bit of a conundrum (the Foghorn taught me that word. I think it's Latin for wtf?): while the Mighty Xarcon provided two links for Fret Doctor in the OP, you can only order it through
be-a-fifer, and I don't want to be a fifer.
I don't even want to support people who feel inclined to fife (fifists?) as it was outlawed in the Constitution (or should have been). Who wants to play an instrument that produces sounds that makes it feel like someone is forcing sewing needles into your eardrums?
We're bassists. We prefer sounds that feel like sumo wrestlers jumping up and down on your chest.
My point - as nearly as I can figure out - is that
be-a-fifer page is the single most informative resource I've ever seen for information about fretboard care:
... Whereas it's impossible to even find Fret Doctor on the
Doctor's own site! Nowhere does it say whether Bore Doctor is the same as
Fret Doctor, either. (I assume it is, but that's mostly because I'm a married man, so I assume a lot, like when I vowed; I do, how quickly that would be countered with oh no you don't!)
I discovered from that page that because I had treated my fretboards (37, at last count) with lemon oil that turned out to be lemon-scented mineral oil, and/or Pledge (the silicone-based polish discussed on that page), I have to get some
Homer Formby's Buildup Remover to clean that crap off the wood before applying Fret Doctor, otherwise it won't penetrate!
If a lack of penetration is concern for you (you know who you are), you need
Homer Formby and
Fret Doctor! It's also interesting that
Fret Doctor doesn't necessarily darken the fingerboard, it actually restores it to its original condition, which is darker (usually )
Grenade Oil sounds interesting (use it on fifers).
