[pianotech] Cleaning the plate

[Dean May]

Yes, 409 contains bleach. If you spray and let it soak it will bleach the
areas where it runs leaving splotchy coloration. Best to spray on uniformly
as possible and wipe off quickly. I like full strength as I find a little
dilution hugely reduces its effectiveness. I mostly use it on 80 year pianos
that are pretty nasty to start out, so I can't make them any worse. 

 

Use a brush or paint brush to work it around hitch pins and tuning pins. It
is pretty nice if you have an air compressor to blow it out of those pin
fields into a waiting cloth. A canister vacuum on the blower side using the
crevice tool will also work at giving you a high velocity air stream.

Be careful with that, "409" can be pretty rough on some finishes.

I like 409. YMMV

List,

 

Does anyone out there have a suggestion as to what to use to clean a plate?
I have a piano in a special setting and could use some suggestions.   I have
used a mild detergent in the past, but this list sure has become a wealth of
information, so I am fishing.
