钢琴琴键日常擦拭：三块布分工，沿着朝演奏者方向收水

avoid cleaners (both liquid and saturated wipe-type cleaners) that contain harsh ingredients such as alcohol (isopropyl), chlorine, ethanol, benzene, peroxide or salts.

Dampen one of the microfiber cloths with lukewarm water and a small amount of dishwashing liquid, then wring it out enough so that water does not drip on the keys.

Take the second microfiber cloth and dampen it with lukewarm water only

Using the third microfiber cloth (but keeping it completely dry), wipe down the keys one more time in that same “toward-the-player” motion until all the keys are dry.

Keeping the key cover closed at all times when the piano is not in use will help keep the keys free of dust and dirt

these recommendations do not guarantee disinfection of the keys, and many currently popular disinfectants may damage key surfaces over time.

If you use hand sanitizer that contains any of the ingredients listed in the first paragraph, make sure your hands are completely dry before touching the keyboard.
