hahahaha.... okok.. if you guys dun want to change strings regularly.. then to generally maintain... i use the following with very VERY good results..
old english lemon oil. - $9.90 from any D.I.Y store... one bottle can last you .. months to a year of daily use.
silicon spray ? - not sure of the brand. but it coats lubricates and cleans all metal /plastic/wood surfaces... perfect if you just polished your guitar...and hate finger prints... this gives your guitar body the "babybutt smooth'" effect.
i use lemon oil on the strings... and fretboard... silicon spray to wipe the strings and neck/body/bridge...etc..every few days...to keep the sleek feel.
no point buying fast fret , dunlop 65...guitar polish etc , just waste money.
the best guitar polish imo is CAR polish. cars go thru 100 times more dirt and corrosion that guitars go thru. i use AURI gold ..polymer..protection...space age mojo crap for my guitars... perfect showroom shine everytime.... and it protects.
