And it depends on how = clean you need to get them. It sounds like you've got a set that has a lot of white powdery oxidation. = To deal with this, what I usually do is wash the pipes down well, with a mild dish detergent (but not too much) and water. If you still appear to have quite a bit of oxidation present, then (and the next step may sound a little strange, but it works) make a cleaning trough of a size large = enough to accommodate the largest pipe. This can be made of wood, with a heavy plastic tarp liner. Buy yourself several gallons of white vinegar. Yes, the same stuff you might find in your kitchen. Vinegar is a mild corrosive. Put the vinegar into the trough, and a pipe into the vinegar. Leave it there for about 10 to 15 minutes (but do watch it; different zinc alloys may react differently). Much of the oxidation should disappear. Any oxide "stains" you may be left with you are probably stuck with. Take the pipe out, wash down the pipe thoroughly with water, and let it dry (a good wipedown doesn't hurt). When the pipes are dry, DO seal them again. Anciently, shellac was used = to seal zinc, but lacquer is probably better, and more durable. If you can = do this inside and out, with a dilute solution of lacquer, you will forestall further oxidation problems. This is probably not the only way to get the result; I would be interested in hearing how others go about it! Greg Rister Pipe Organ Craftsmen Pomona, California > [Original Message] > From: Fr.

I'm curious as to what type of acoustic board do you use? I agree that = the fiberglass may be dangerous in my application, let alone flaking off and getting into the mechanism!

It appears to be a cellulose/paper type product about 1/2" thick with an asphalt coating on one side. It is dark gray. It is VERY cheap: like $4 for a 4x8' sheet. And it's easy to cut. = It worked in the previous projects. Does anyone know if this would be preferable to fiberglass? Not being in the trade, I am sort of limited to what I can pick up at Home Depot, = Lowes, etc. Thanks, Dave _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

I don't remember the name, it is a yellowish 3/4 sheet 4x8' and as I = recall correctly, it runs maybe $60 a sheet. It has a smooth flat hard sort of surface but it's still fiberglass...
