The current Coronavirus pandemic brings questions to the fore about how to eliminate the spread of infectious and harmful microorganisms in our teaching or practicing spaces. One of the most burning ones is what can be done to sanitize or disinfect piano keys without harming them. Piano manufacturers advise against using any form of alcohol, but what\u2019s the alternative? And during an ongoing pandemic when public health have higher priority than material concerns, do we need to re-evaluate the advice?<\/strong><\/p>\n

\"\"<\/p>\n

Occasionally, we all carry viral and bacterial pathogens on our hands, disease-causing organisms that are likely to end up on keyboards. As a consequence, pianos in teaching and practicing spaces, played on by many different people, risk contributing to the spread of diseases.
\nIf teaching, it is obviously a good idea to require effective hand washing or sanitizing before and after anyone plays your piano. But this will not help against, say, any coughing or sneezing that may happen during a lesson. And when faced with a new instrument not knowing who has played it before you – what can you do to sanitize the keyboard before touching it? <\/p>\n

How to clean piano keys?<\/h2>\n

Alcohol based disinfectants<\/h3>\n

The most efficient disinfection would generally be to use some kind of alcohol such as rubbing alcohol<\/a> or denatured alcohol (methylated spirits)<\/a>, but be aware that this could damage the keys. It\u2019s especially risky on an older instrument with ivory keys. But as a matter of fact, both ivory (a natural polymer) and synthetic polymer key surfaces can become discolored or cracked when exposed to alcohol or other harsh chemicals used in disinfectants.<\/p>\n

Disinfectant wipes, warm water, or vinegar?<\/h3>\n

Some piano teachers wipe their piano keyboards with various disinfectants after each student. Is this because they are unaware of the risks of damaging the instrument, or is it that they see no alternative? Or that they have done so for years, and found that the potential health benefits outweigh the potential risks for the instrument?
\nSome recommend using a solution of water and vinegar, but science is still very scarce on vinegar’s effectiveness as a disinfectant. Clearly, it\u2019s not nearly as effective as chemical products. And you need to allow at least a half-hour of exposure. Also, one would think vinegar a more gentle alternative for ivory keys, but this is not the case. If your keys are plastic, vinegar won\u2019t hurt, but when dealing with ivory, avoid it altogether.
\nIf you want to be really gentle on the keys, you could simply wipe them down with a damp cloth (NB. damp, not wet – nothing spells destruction for a fine instrument like moisture damage). This will not kill viruses and germs but hopefully removes them physically. It’s far less likely to damage the keys than disinfectants, but probably less effective.<\/p>\n

The polymer chemist’s approach<\/h3>\n

John M. Zeigler, Ph.D., a polymer chemist also interested in music, has tackled the problem of disinfecting piano keys safely in his article “Piano Hygiene in the Teaching Studio”<\/a>. Zeigler found that certain disinfecting wipes (with so-called \u2018quaternary ammonium chlorides\u2019 as active ingredients) should be safe for use on piano keyboards, because they contain mostly water and only a very small amount of the disinfectant. Nevertheless, he recommends wiping with a damp cloth afterward to remove disinfectant residues. He also issues a word of warning: Unless you can understand the nature, chemical reactivity and purpose of the label ingredients for a cleaning product, avoid using it on your piano.
\nDon\u2019t forget to wash your hands!<\/p>\n

New recommendations from PTG<\/h3>\n

Piano Technicians Guilds has recently published the document “Covid-19 and Piano Care”<\/a>.
