Filling & moisturizing

These are 2 essentials when it comes to basic guitar maintenance, well, as far as my practices are concerned...

• IKEA's Skydd wood mineral oil: Beez & I are currently using this fluid to treat open-pore wood eg: rosewood. The fact that it's a safe fluid to be having at home is a plus, especially so when I have a daughter here who always handles my equipment.
• Elmer's Wood Filler: If you screw-unscrew cavity covers, pickguards, truss rod covers, etc. repeatedly, the screw thread might wear out the cavity grooves & ill fitting (loose) will entail. The convenient remedy would be to insert some matchstick bits in there but upon unscrewing, the loose bits will not get undone & the screw remains in the cavity despite you turning it repeatedly. I'd apply the filler sparingly, it's not my intention to plug the hole entirely, just line it against the cavity wall & let it dry, preferably overnight.

Hydrate

Planet Waves now has a fretboard moisturizer/ conditioner for all your sorry, dry rosewood fretboards. It comes in a spray-ready bottle, no bigger than one of your sister's facial/ hair revitalizing products.

When I started out, there were hardly any fretboard cleaning/ rejuvenating products out there. We resorted to furniture cleanser to double up as our care kit implements. These are perfectly alright for this measure but the chemicals in them might prove to be too harsh for our rosewood's longevity.
