1 Jimbodiddley 1 month ago Last time I had my acoustic (1981 Epiphone flat top) in to the shop, the tech mentioned that the tuners would eventually need a good cleaning. I had noticed that over the years, a few of them had become stiff and hard to turn. I found this video on the Stew-Mac site, which seems to explain pretty well how to go about it. Couple of questions: I have naptha (lighter fluid). I guess it's all pretty much the same? In the video, he uses Tri-Flow lubricant. Not sure if that's sold here in Canada. Is it like WD-40? Could I use that? I see there are "dry" silicon lubes and "wet". Does it matter? Anyone have any other advice about tackling this job? Much appreciated.
