Re: [Harp-L] Slide lubricants - food grade grease (NSF 51/61)

Almost anything you can put on  slide that won't evaporate has the potential to:

1) Attract dust and other undesired particles;

2) creep into the harmonica and stick to the valves, potentially sticking valve layers together and sticking the valve to the reedplate.

Additional downsides can include rancidity, toxicity, etc.

Some folks report good results with various lubricants, but I'd err on the side of caution.

Subject: [Harp-L] Slide lubricants - food grade grease (NSF 51/61)


I recently purchased a "food grade" o-ring lubricant (to repair a potable water system).   It's a silicone grease for use in areas where food is prepared (health code food standard NSF 51/61).   Very slippery and suitable for plastics, perhaps suitable as a slide lubricant?  It's called Molykote 111 from Dow Corning (Silicone Dioxide).   Link to Material Safety Data Sheet below.   I have not tried it, any comments on slide use?
