Drugstore Alcohol (as Antibacterial)

post #1 of 4
Thread Starter 
Stupid question: my girlfriend is looking for some alcohol to use as an anti-bacterial - she has a number of young piano students, so she likes to wipe down the keyboard after each student to minimize chances for transferring cold viruses, etc. When I looked in the drug store, I was surprised to see a bunch of different types - 70% isopropyl, 90% (I think), rubbing alcohol... anyone know what the differences are between these, and whether any would be better than another for this purpose?

The ~90% isopropyl should be fine. Rubbing alcohol is the common name for isopropyl. The 70% is for skin usage, I guess. It will dry out your fingers though, so she might want to wear gloves or use a thick rag so it doesn't get on her fingers. Also, it can eventually damage whatever the keys are made of. If it's a student piano, probably not real ivory, but in any case, repeated use of alcohol on even plastic can eventually weaken it and lead to it becoming brittle. I use it on my mouse and computer keyboard from time to time, and very rarely on my (music) keyboards and music equipment.

Thanks for the reply, though I guess we should check on the possible effect on the keys. It's a Steinway grand -- don't ask me what model -- I'm completely ignorant on that score...

Definitely, in that case, ask a piano dealer. I have no idea on pianos either, but I recognize a Steinway as one you wouldn't want to go dumping random chemicals on.
