Pianos are often irresistible to children – as are chocolates and sweets. It’s lovely that they’re interested in music but you don’t want their sticky fingers on your piano keys! If you do find that the piano keys are sticky, they can be cleaned by the piano tuner on my next visit to your Sheffield home. I use a keybrite solution sold by my loyal piano tuning suppliers, but if you endeavour to clean them yourself, use a warm damp cloth followed by a dry cloth and make sure you keep the dirt from getting down the sides of the keys. For any other questions, call the Sheffield piano tuner.
