How do I clean my keys?
Carefully! The ideal cleaning substance is Cory Key-Brite, which can also be purchased at Starbird Piano in Portland or through me. Lacking this, the actual keytops can be cleaned with Windex on a cloth, provided that the cloth is only damp. You don’t want the keys to get wet, as that might cause keytops to come unglued or, if you get them quite wet, might cause warping.
Another good product is MusicNomad’s Key One Cleaner. This is a much thinner product than the Cory Key-Brite, and is used more like Windex. I use Cory Key-Brite when doing detail work, but Key One is also a good option if you’re wiping down your keys on a more regular basis.
How do I clean the rest of the piano?
Microfiber cloths dust off the outside of the piano effectively. If you have a high-gloss piano, it is worth investing in Cory Super Gloss Polish, which can also be purchased at Starbird Piano in Portland or through me. On other finishes, you can use Murphey’s Oil Soap if the piano needs a more serious cleaning. Cleaning underneath the strings of a grand piano is an involved process, generally taking two to three hours. This is a service I provide; however, if it is something you are interested in doing yourself, or you are located outside of my service area, consider purchasing your own professional piano cleaning tools:
Spurlock Tool’s “Squeegie Type” Soundboard Cleaner is a very professional tool costing about $80, but will give you excellent and reliable results, without having to remove the lid of the piano. Alternatively, the First Chair Soundboard Duster is a much simpler tool (about $30) for dusting underneath the strings. Soundboard steels are the most inexpensive option ($5 plus the cost of a microfiber cloth), but they are a very labor-intensive option and will require removing the lid of the piano.
My piano smells awful! What can I do?
The folk remedy for piano odor, which I learned working on consignments at Starbird Piano, is to put dryer sheets inside the piano. This is quite effective in dealing with smoke odor, but as with any strong, offensive smell it’s important to find the source of the problem. Over the years, I’ve seen a number of pianos devastated by moths, mold, and mice. If you believe your piano has fallen victim to any of these, it needs a thorough and professional cleaning as soon as possible.
Often, in cases of serious mold, I will clean the piano out and then install a Dampp-Chaser dehumidifier system inside the piano to make sure the problem doesn’t return.
Moths are eating the felt in my piano. What now?
Moth larvae love piano felt, and they bore into it enthusiastically. The initial removal can be pretty difficult. Once the larvae are inside the felts and the hammers, they’ve already done quite a bit of damage and a proper solution would be an action rebuild. If this is unaffordable, the piano is older, and rebuilding is unlikely in the future, a product such as Fortefog Natural Protector can be set off in the same room with the piano with the case left open. The moisture in a fogger is not good for the piano, but it is considerably better than a live moth population.
What can I do about mold?
Mold invades the felt and the wood inside the piano, and it can be extremely difficult to remove in older pianos where it has been allowed to flourish. Newer pianos are generally chemically treated, and mold invasions tend to be much smaller in scale. However, in any size invasion, the entire piano needs to be professionally cleaned and treated with the action and the keys removed. After this cleaning, you’ll want to completely dry out the piano, and the standard technique for this is leaving the piano open and exposed to direct sunlight for a period of several days.
Another excellent strategy is the installation of a Dampp-Chaser Piano Life Saver System™, or even just the Dampp-Chaser dehumidifier which is considerably less expensive than the complete system. This is especially important as a long-term solution in pianos that are exposed to winter temperatures, such as church and hall pianos.
What about mice?
Mice can do colossal damage, but seldom do in newer pianos because of their chemical mold treatments. In older pianos, if the colony nests inside the piano, the damage can be devastating. The first response is a total cleaning and an evaluation of the damage to moving parts. Additionally, mouse urine can cause warping, sticking keys, and mold. Once all visible evidence is removed and parts are replaced, there are two possible forms of prevention. Treating the house for mice is ideal, but if that isn’t possible the piano interior can be thoroughly scrubbed with a solution containing peppermint oil, and a saturated cloth left in the bottom. Any visible openings can then be covered with hardware cloth. Another inexpensive option is ultrasonic rodent repellent, but clients have reported mixed results with these.
Can I polish the strings?
Sometimes, piano dealers polish the strings using 3M pads and steel wool. This can only be done to treble strings, not copper-wound bass strings, and will almost certainly throw the piano out of tune. If your strings are regularly breaking or are severely rusty, it might be worth considering having your piano restrung by a rebuilder.
