How to Care for Your Piano

Updated: May 25, 2023

Every Let's Play Music family needs a piano or digital piano for years 2 and 3 of the Let's Play Music curriculum. Get tips on what to buy with our buying guide. Now that you've got that taken care of, you might be wondering how to take care of your lovely instrument.

Moving the Piano

Perhaps your piano is already nestled in its permanent home, but if you've just purchased it or are moving house in the future, please consider having professional movers deliver it. The correct equipment for moving pianos includes using ramps, piano-moving boards, piano dollies, piano-lifting straps and protective padding. Professional movers can get your piano in place without damage (and minimal knocking out of tune.)

Chances are, your upright piano is up against a wall, as is mine, because the back of the piano is not all that attractive. Experiment with pulling it a few more inches away from the wall, since most of the sound comes from the back, and this will allow some space for some nice resonance to help you get that sound projecting into the room. You might also consider using the piano as a divider between two rooms or spaces: cover the back of the piano with fabric for an attractive appearance, and be rewarded with the acoustics.

Key Cleaning

Sticky peanut-butter fingers are not the only things that take the shine away from your piano keys. Just the oils and daily dirt on fingers can do the trick. It's a fine idea to institute a "washed hands" policy to reduce the frequency for key cleaning. Another fine habit is to close the cover when not in use to prevent dust on the keys.

Avoid using anything abrasive (chemicals, cleaners, or even paper towels.) Use a flannel or microfiber cloth with some warm water, and wipe each key towards you (not side-to-side) making sure you get the sides of the black keys as well as the tops. Only clean one octave and then quickly wipe it dry before moving to the next octave. A gentle soap is okay if your keys are plastic.

If you are wanting to disinfect your keys during flu season, use a solution of 3:1 water:vinegar and wipe down as above.

Cabinet Cleaning

Modern pianos are finished with a variety of laquers and resins, designed for beauty without the addition of any wax or polishes. Dust your piano with a feather duster or a specific piano-dusting mitt, or wipe away smudges using a slightly damp flannel using long straight strokes.

Since pianos are 85% wood that expands and contracts with humidity, you can protect your piano's finish, case, and pitch by avoiding swings in temperature and humidity whenever possible (the garage is not a good permanent home). There are even piano-humidity devices available, and your kids will laugh every time you remind them to "go water the piano, please."

Your piano's beautiful finish hates direct sunlight, and live houseplants should never go on a piano. Actually, you shouldn't set items on your piano unless there is a soft cloth protecting it, or scratches are likely to ensue.

Tuning the Piano

With the ear-training you and your child receive in Let's Play Music class, we hope you notice if your piano is going out of tune. Even if no one uses the piano, it goes out of tune over time simply because the strings are under high tension and they slowly stretch.

Here's an interesting thought: if all of the strings stretch slightly, your chords and intervals may still sound correct even though the pitch is slipping! Don't wait until you notice that your chords and intervals are sounding poor to get a tune.

Professional tuners will tell you that 6 months is the longest you should go between tunings. Waiting longer, and letting all the pitches drop dramatically, poses a real challenge for getting a piano back into tune: when each string is tightened dramatically it interacts with the neighboring strings, knocking them out of pitch. In that case your tuner will conduct a pitch-raise (dramatically increasing tension on all of the strings) before tuning, and you'll get an extra charge for it. It's much easier (and maybe cheaper) to get a piano in tune if it is always kept tuned-up.

My favorite times to tune the piano are in September and March, simply because I want the kids feeling confident as they start up a new year in Let's Play Music, and again as they are preparing to perform their compositions in the big spring recital.

You do not need to re-tune your piano if you move it from one room to another in your home, but if it spends a significant time outdoors during them move, perhaps in a moving van, the fluctuation in humidity could knock it out of tune. If it is only outside for a short while, you may be fine.

Brand new pianos, straight from the manufacturer, have strings under tension for their first time, and they will stretch a lot in the first year. During that year, 4 tunings are recommended.

One more caution: before buying a used (or dangerously free) piano, be aware that if a piano has been flat for too long, it may be impossible for the strings to handle the string tension to get them back up to Standard Pitch (A440). Buy a certified used piano, or hire a tuner to check it out for you before you buy.

Good luck and enjoy your piano! It could bring you (and future generations) much pleasure for up to 100 years!
