Cleaning your fretboard

From a professional standpoint. 3 in 1 oil is a huge no no. It collects dust grime and gunk that you really dont want imbedded in your fretboard. Alcohol is fine as long as you follow it with lemon oil to replace the needed moisture content in your fretboard. Most waxes and polishes just build up on the fretboard leaving it gunked and unpleasant to say the least.
If your going to clean your frets, use masking tape on the open fretboard areas to protect them while you polish the frets .
Lemon oil is actually a wonderful thing, it replenishes lost moisture in the fretboard and helps to keep the cellular structure of the wood stable which helps keep your frets nice and tight in the fretboard. This also helps to keep frets from raising up .
If your on a budget like most of us you can buy Lemon oil in the household cleaning aisle at most discount stores like walmart in a 16oz bottle for under 3 bucks. A 2 ounce bottle will run you that much in most guitar shops.
Use a soft lint free cloth. (flannel dust rags work great) Saturate a portion of the cloth and apply it to the fretboard allowing it to soak in. Repeat this till it stops soaking in the lem-oil. Wipe off any excess afterwards.

Goo Gone would work. but i dont think its made for bare wood such as a rosewood or unfinished maple. Its designed for removing paint and other chemicals. Its a pretty harsh solvent to be using on something of that nature. That would be like washing your car with paint thinner. Simply wiping down your guitar after playing takes a few seconds. and saves loads of work later.
