Wear gasmask, goggles and gloves, take outside and put on cardboard, and blast all bushings with non-chlorinated brake part cleaner, then Protek, when dry. ( A day or two ) . I won't be held responsible if there's plastic in there, or something, which is damaged by this method, but it's the most effective I know of to flush junk out of bushings. ( I did it on a terribly verdigris'd Steinway 2 months ago, and its' still nice and free--even without the Protek ! ) Thump --- Gene Nelson <nelsong at pbic.net> wrote: > Hello list, > Here again with more bushing woes. > Have a client with a relatively new (8yrs) Nordiska > 5'8" and all of the hammer flanges are tight.
