3 or 4 outdoor gigs in this heat ,humidity and sweat , is about as far as I can go without cleaning , maintenance and new strings, And that's pushing it . I feel it . The strings are the 1st to go but I live with them for 3 or 4 shows which could be +/- two weekends. sharing my process: 1- Remove strings and inspect the fretboard , frets and saddles 2- Clean the whole guitar with polish , Dunlop 65 seems reasonable 3- Clean the saddles thoroughly with an alcohol wipe 4- with 1200 grit paper, polish the tops of the frets, sometimes 600 is needed. This is done very lightly and not overdone , but get the dirt off the frets. 5- clean the fretboard and neck with the polish 6- clean the nut slots with the appropriate gauge files, very lightly . You would be surprised how much grit is removed. You want to be very careful here as to not alter the nut slots. A minimal amount of cleaning goes a long way. An alcohol wipe can be used here as well. 7- Put some NUT sauce in the NUT slots. 8- ok time for new strings . This whole process working slowly takes about 45 minutes or less and man is it worth it !
