guitars

I'm just some guy on the internet but most guitars are mostly wood, and that reacts structurally to temp and humidity so care can mean different things depending how close you are to the tropics or polar regions. Too cold and dry gets brittle and easier to break/split, fret sprout, etc. too warm and humid and easier to bend, warp, etc.

I'm in a place that gets all seasons but has some very dry cold months, I keep a humidity pack in cased guitars for storage & re-wet monthly & use wood oil once a year. The couple I use often I'll restring around monthly and clean with a damp cloth then use a wood oil on the exposed wood neck/head/back. Haven't had a neck split or cracks develop yet so it seems to be working. I wouldn't use alcohol that seems way too drying unless I was in a more humid/warm environment or there was some serious gunk to clean off.

All that said I'd really like to try a carbon fiber guitar at some point, they seem to be resistant to all that stuff and have been getting cheaper but I'm not sure if the cheaper ones use a polymer that's just carbon fiber in name or something like how would you even test that.
