ItS SimPle LiFE!!!

Now the cleaning must be done in order to remove the waste products from Guitar body as we humans do :p .As we play, dead skin cells, sweat, and dirt build up on the fretboard and collect around the frets. Not only is this unattractive, but the moisture, acids, and salts in sweat cause the wood around the frets to deteriorate. This can cause dry rot in the fretboard, which results in loose frets and very expensive repairs.THe worst scenario if you dont clean it,the sweat which gets absorbed by fretboard, and as time passes on this sweat gets evaporated and thus resulting in to cracks in fretboard, they can corrode the coils and magnets, causing the pickup to fail. Same is for Daa corrosive materials,Which have the same effect on potentiometers and switches

Secondly,about using The conditioners -they really help in retaining the texture,polish of  guitar surface. But the most important factor regarding the use of conditioners are their ingredients, most of these products, including lemon oil, contain harmful chemicals and solvents that will damage your guitar’s wood and finish. Avoid anything that contains d-Limonene, alcohol, or silicone.  Derived from oil extracted from citrus rind, d-Limonene contains natural acids. These acids can act as a solvent and break down finishes and cause the wood around the frets to deteriorate. Alcohol dries out the fretboard, bridge, and other unfinished wood, and can cause cloudiness in certain types of finish. Silicone prevents the wood from breathing and can cause the finish on your guitar to become hazy. It’s also very difficult to remove.

And last but not least,Humidity. Conditioning wood certainly helps prevent it from cracking but it’s also a good idea to use a humidifier Maintaining a guitar-friendly humidity level helps prevent wood from cracking. 

so now

starting by cleaning the guitar bodyPut the compound on clean cloth(preferably nano fiber). If your finish is still hazy after cleaning, some light rubbing compound can be used to get the shine back. Keep in mind, though, anytime you buff or polish your guitar with an abrasive compound you are removing small amounts of finish, so use sparingly.

Fretboard conditioningFor built-up fingerboard grime,  use combo of compound and an old toothbrush with the bristles cut down to make them stiffer. Spray the cleaner on evenly, making sure not to get any in the soundhole where it could stain the label. Then attack the buildup in a circular motion with your toothbrush. This can be messy, so keep some rags handy to wipe away the dirty liquid. When you have a nice clean fingerboard, let it dry and clean off the toothbrush.Rub it in with a paper towel until the board looks good 

Humidifying Try running an ultrasonic or warm mist humidifier in that room.
