[pianotech] Whitening yellowed ivories

[Gregor _]

Steven,

it´s not a dramatic procedure. It´s just restoring the original condition. The makers of these pianos did it too. The ivory was sanded and polished before the piano left the factory.

I placed a post earlier this week with a similar question and got no reply.  We're busy I know.

 

I wondered about the Klaviermacher video in which he sanded the ivories a great deal.  I wondered if this would produce the expected feel of real ivory keys?  If you sand off all of the ridges of natural ivory to produce a very smooth surface and albeit white will the pianist appreciate the tactile feel of this or could it ruin what a performer wants to feel?

 

Just curious and being careful before doing anything dramatic.

 

Thanks,

 

Steven Hopp

Put them under a blacklight overnight. It will take some of the yellow out, but they will not look white because the stain is probably too deep in the pores of the ivory.  
If you know you're going to have sunny days, you can put them outside in the sun for several hours at a time.

I know I have read articles somewhere about different ways to "bleach" or
whiten yellowed ivory keytops, but I can't seem to find them. Does anybody
have any good tips for how to accomplish this? The piano is extremely old
and was in a smoker's home for many, many years. I'd also welcome advice
on what pitfalls to avoid in doing this job. Thanks in advance!
