Wipe down the valves with denatured alcohol.
Get some lint free cheeze cloth and soak it in denatured alcohol and swab out the valve bores. Make sure don't leave any lint or fuzz in or on the valves. Lubricate your valves with your favorite valve oil.
The air passageways in the valves may have corrosion products inside. Clean them with denatured alcohol. (Use ethanol or methanol. Pure vodka or Everclear.)
Let me know how this works. I have to do this to my Yamaha/Shilke pic when I haven't played it for awhile. |
Thanks, I'll give that a go when I get a chance (I'm away next week, so probably not until after then)

It's an entry level one, so it is pretty crummy.
