Never use lemon oil...the oil will run under the frets & soften the wood and loosens the frets.
Clean head to toe when you re-string...watch closely the bridge & stud height adjustment screws & bolts as you wipe, so you do not move these parts...and thus change your original string height. Use the painters 3M brand removable tape to tape down these movable parts. I use Gibson's POLISH or Martin guitar's POLISH...not wax....If you clean your guitar reguilary...you should never have to wax....who does anyways?...perhaps older finished guitars.. Use Q-Tips to dust in tight places....and never leave your guitar out of it's case for long....sorry, they are cool just to look at.
For string cleaning, I use Fast Fret ...for $6 to $7 a can that contains a felt wand soaked in cleaner. Use it gently when new cause the wand is very juicy when new. The Fast Fret is not scented nor smelly...a real neutral smell. It lasts forever...you'll buy one a year maybe. I also use their spray can formula when I play, if my hands or strings are dry.....just spray up the fretboard real quick. Use the cloth provided with the Fast Fret wand to wipe strings down & when it gets dirty, hand clean it in the sink with mild soap....like Dreft baby powder soap, or other mild soap.....anyways. I always wipe down my strings after playing, with at least a dry white lint free towel. See your mom for some old hand towels that dont produce the lint. I take hold of each individual string, sliding some of the rag under it & zip down the neck cleaning all "sides" of the string. Old cloth baby diapers that have sewed edges work nice & wont fray after washing....or go to a a fabric store & buy some flannel...have them cut it for you...buy a light color so you see dirt building on the cloth faster than a dark towel. Take this flannel home & just keep washing it as you do laundry to really soften it.....or just buy a cleaning cloth at the G store.....duh Dan!....Sorry.
You can also use lighter fluid on today's finishes to get old build up off the fret board with a tooth brush...test in an inconspicuous place first.....but the rule is to always scrape with something softer than the surface...like a finger nail, then a tooth pick if your nail doesnt work. But really the first thing to use to clean funky stuff, is to first try your hot breath & a cloth, then work your way up the cleaning solution ladder. I also use Fast Fret (wand) on the fret board after removing strings to put a gloss on the LP rosewood fretboard, then lightly polish the extra off. This Fast Fret has some ''oil'' like conditioning to it, & I think it helps keep the board clean and not dry looking.
For the frets...try using somthing softer than the fret wire...like a pencil eraser...but you shouldnt have to clean/polish the frets. The hardest place is where the wood meets the fret, so use the Fast Fret wand and a towel.
The best advise here should come from thoughs of you with black guitars...the funk really shows on them.......Oh... I have a black Strat.!? >> Sorry so long ..>>>> DAN
PS...when polishing the wood...just polish the head stock, and between the pups, and bridge area...anywhere the strings get in the way. Then take the Fast Fret to the board, and wipe off extra. Re-string the guitar. Then lastly, polish the rest of the guitar ....cause as you restring, you are handling the guitar...putting more body oil on the finish.
I use the liquid Keyser string cleaner (white bottle) in the nut if the strings pinch, or use pencil lead on the wound strings if they pinch in the nut.It has a dauber felt applicator, and is just pure liquid so dab gently....For bridge saddles that stick, use sewing machine oil....a very light weight oil, and dilute it with some lighter fluid, and add drop on the stuck part.........That's all the lubing today.
