I agree that hanging it on the wall (I have some foam mounted in behind so the body can't get knocked directly against the wall,) in a climate controlled room, temperature, and humidity, is the best storage method. As stated above I use a drop of 3-in-1 oil on parts that are subject to rusting.

Also if you have rusted parts, you can give em a bath in a diluted Naptha solution(3 parts Naptha, 1 part 3-in-1 oil,), followed by a dip in some acetone to clean em up.

Also maple fretboard, i just clean the same way as the body, like people said above, clean cloth, maybe some breath if needed, not big on polish.

Rosewood will need treatment 1 or 2 times a year, depending on climate. I treat it the same time I do a set up, and maybe a trussrod adjustment. The feelings on 'lemon oil' are mixed. some feel it can attack the glue on the frets, but I think those people are absolutely soaking the board, when you need only a really small amount. Personally I follow Dan Erlewine's advice and use Linseed Oil, Pure Linseed Oil, not the boiled stuff, although some people use that too. Just trail a small amount on, with a 'Q-Tip Swab' use very little, and be extra careful around the fret slots, and wipe off after a minute. The issues people have with the various treatments seems to be when they use a lot.

I'm not an expert, but I play one on the internet.

I'm not worried about it at all. I would just like to keep it in a good condition for a long time so I can get to play it for a long time.
I know I can't keep it in a perfect condition forever. I play it every day and I don't want to get ruined too soon.

I agree with that, that's kinda why fender came out with the road worn series. I play my guitar alot out in public and I want the people to enjoy my guitar visually as well. I worked hard for my axe and I want to keep it looking good as well as sounding great! Thanks for the tip!
