The piano is one of the most complex instruments to maintain. It has more than 500 working parts in the action and a combined tension on its strings between 15 and 20 tons. Tuning it correctly takes a great deal of expertise and you should not try to tune a piano yourself.
Most Piano Manufacturers recommend that you have your piano tuned four times in the first year. This will help adjust your piano to the new environment. After the first year, the piano should be tuned at least twice each year.
Be sure you choose your piano technician carefully, just as you would with any other professional service. Larry Ray is certified by the American School of Piano Tuners and he has been tuning since 1992 on a wide variety of pianos. If you live in Wichita or the surrounding area, give him a call or send an email for a service visit or any questions you might have.
Never leave a drink on your piano. This is probably the most common reason for a damaged finish.
Also avoid placing lamps and plants on top, unless there is a felt bottom to protect your piano.
New piano finishes generally require only occasional cleaning with either a dry or damp cotton cloth. Older piano finishes may benefit from an occasional polishing with a good quality polish, but frequent polishing is not recommended. A piano's finish is best maintained by simply keeping it clean and avoiding exposure to direct sunlight, extremes of temperature and humidity, and abrasion.
The keys will eventually become dirty from finger oil and use.
For the white keys, use a damp cloth of water and mild soap. Make sure there is no excess water to seep down between the keys. Be sure to wipe the keys back-to-front rather than side-to-side. You should clean only a few keys at a time drying and immediately go over with a dry cloth. Ivory keys are porous, and excessive moisture can penetrate and loosen their glue joints. Also, a dirty or brightly colored cleaning cloth can transfer stains into the ivory. To clean sharps, use the same process, but be sure to use a different cloth to avoid black stains on the white keys.
It's best to let your technician clean the exposed insides of your piano, as some of these pieces are fragile.
Your piano should be placed on an interior wall, not an exterior wall. This keeps the extremes of hot and cold from warping and finish damage.
Your piano should also be placed out of sunlight as much as possible.
