An old donated upright with ivory keys came to the facility with two keytops with wide scotch tape on them. The middle C key and the G below it had the tape on them. I do not know why the tape was ever put on the ivory keytops.... but I'd like it off completely so those keys will feel like the others around them and not sticky. :rolleyes:

The taped keys bothered me while playing as it had a rough serated like edge from where the tape was torn from a dispensor so I peeled one of the pieces off--- and now I have a literally sticky key as the tape residue remained on the middle C.
(Another sigh.)

Any techs have any ideas I can try (at my own risk) on how to safely remove the gummy glue like residue from the old ivory keytops. (Praying hard for help.)

Thank you to any who can offer me any ideas I might want to consider trying at my own risk to solve this ivory keytop problem.

Also any other ivory cleaning tips would also be appreciated here also. The keys are dirty and need cleaning so I will be busy on this "project".
( ;\)

Off to bed... it is late and I really should be resting up. But wanted to get this plea and questions posted so I can get started on the "ivory cleaning project" I now have at hand.

Ivory is fairly resiliant.

Naptha
Goo BeGone

Even laquer thinner.

Then clelan up with a damp cloth with a little soap.

Nothing so "wet" that is flows over the sides of the keys.

I like acetone for that and you have some if you paint your fingernails. Use some polish remover.

Why do you think they named it Ivory soap?

I prefer less volatile solvents such as mineral sprits. Laquer thinner (acetone) might take the coating off the black keys, and may damage the finish if you spill some on the cabinet. In addition, many people can't tell ivory keys from plastic, and using acetone on plastic will damage it.

In a pinch WD-40 oil works. All you need is something to cut the adhesive. Always apply the solvent to a cloth first, never directly on the keys. Use just enough to do the job. When the adhesive is gone, clean the keys with a damp cloth and soapy water.

Thanks for all of your responses to my question; Very much appreciated over here.

Ah Naptha. (Larry Buck mentions this one).
I recall some guitar techs use that stuff to get the gummy residue off guitars when they take off an old pick guard. (I learned about it on a Gibson Guitar Forum at the Gibson Website). What exactly is Naptha anyway? I don't think my chem. teachers ever talked about that stuff.

The black keys are ebony. I'd like to protect them also, so maybe I'd steer away from the acetone.

So there seems to be many options here to try...
so help steer me to a good first choice. I am sure there are pros and cons to each on, so which would be the safest/easiest stuff to try for "ousting" the gummy residue form the ivory.

The soap if used after a hopefully successful "scotchtapectomy" operation will be Palmolive (tempted to use ivory but I always thought palmolive was the "gentlest" on my own sensitive skin).

I have asthma, so whenever I clean off a key or keys I apply a small amount of stuff to the cloth I am using anyhow, to minimize breathing the junk in.

My father's workshop probably has some Goobegone around.

Since there seem to be so many options I am feeling overwhelmed a bit about the choice as to which stuff to try.
So I will issue a little informal poll (please don't be shy as I need help here):

Those who wish to vote on what I might try first (and hopefully will do the trick) can vote here or PM to myself your vote or choice(s) if you are more comfortable with a private reply to myself the "beleagured "old-donated-piano"
cleaner-upper.

And if you wish to, share your reasons (pros/cons, or about previous experiences removing sticky gluey stuff from ivory) for your choice.

Choices given thus far:
1)Naptha
2)Goo BeGone
3) lacquer thinner/acetone nail polish remover
4) Mineral Spirits
5)rubbing alcohol or EtOH
6) WD40
7)other (please mention your other idea here)

I have been ill so I may not get back to all as quickly as I prefer to.

Thanks to all here who have contributed so far to helping me out on my mission to clean up the ivories of this old but needed facility piano.
And thanks to any folks who respond to my informal "poll" also.

I am hoping the poll can give me a bit of direction of stuff to try (at my own risk of course).

(who wishes now I can talk to my chemisty instructor I had years ago)

Naptha or Naphtha Oil is what gasoline is one stage before its final refinement- a very light fuel oil, good solvent that dissolves carbon, great for engines too.

Naptha will not harm the finish.

If you are concerned, naptha should be your first choice.

Available in any hardware store.
Wal Mart has it.

Thanks guys;
I will try out the Naptha. I think we have some in the garage.

If it is safe enough the Gibson guitar repair folks use on guitar sound boards to remove the adhesive residue left over after removing the old pickguards, surely it should be ok with ivory. I'll proceed with caution just to be safe.

I hope to get to work on the keys this week before I have to play the piano again.

Again thanks to all here for the suggestions to try.
