<div> The easiest way to clean the grub is with a soft pencil which will not only dig out the crud but lay down a surface of graphite as a lubricant.

(or rusty), even here in Hawaii. If you have a set that is rusty, unless they are really bad, or are breaking, I would leave them alone. The only thing on butterfly springs that need to be cleaned out is the groove in which the bend end sits. That, over time, can get very gunky, and will drag the fly, which will impede repetition. You can clean most of the gunk out with a sharp tool, like a small screw driver. However, you don't want to eliminate the lubrication, because that keeps the spring riding the in groove with ease, and even eliminate a noise spring. <br> <br> <div style="clear: both;">Willem (Wim) Blees, RPT<br> Piano Tuner/Technician<br> Honolulu, HI<br> 808-349-2943<br> <a href="http://www.bleespiano.com" target="_blank">www.bleespiano.com</a><br> Author of <br> The Business of Piano Tuning<br> available from Potter Press<br> <a href="http://www.pianotuning.com" target="_blank">www.pianotuning.com</a></div> <br> <br> -----Original Message-----<br> From: holly quigley <<a href="mailto:hollyquigley@gmail.com">hollyquigley@gmail.com</a>><br> To: <a href="mailto:pianotech@ptg.org">pianotech@ptg.org</a><br> Sent: Thu, 26 Jun 2008 12:32 pm<br> Subject: Flitz for repetition springs?<br> <br> <div id="AOLMsgPart_2_ab287b54-e14f-4dad-80e4-812b1e508518">I've searched the archives and can't find anything, but I swear I remember someone recommending cleaning crusty (butterfly-style) repetition springs with Flitz.
