I'm fixing a keybed on an old Roland RD600.
Started reading about different lubricants for the plastic parts, but there seems to be many opinions about what to use.
Some suggests Silicon Greas, while other points at Lithium Grease. There are also they who only uses original grease from manufacturers like Yamaha.
Since this forum is equipped with members with great know-how, I kindly ask for your experience and advise
Which lubricant do you recommend?
