Fixing The vital Slip

The an essential slip is vital piece come the tool casing. It houses the front part of the piano keys and also helps protect dust and also other objects from acquiring underneath them. During routine piano maintenance or simply leaning versus that key slip, periodically it can gain jammed up versus the white keys.

When this wake up you’ll start experiencing sticking keys. Occasionally this have the right to be one key, but I’ve discovered that several secrets stick in this case. Since the key slip is one long piece that wood, it’ll have actually an also impact throughout the board in many cases.

It’s really easy for things to loss into a piano as soon as you’re no looking. Exercise pianos in ~ schools, churches and under constant use will most likely have this issue.

When the loss board is raised you’ll an alert a tiny gap there. It could not look favor much, yet it’s certainly broad enough for objects of all sizes to fall into. Heck, I’ve even dropped large pages of sheet music behind the autumn board before, therefore it’s quite typical for this to happen.

To clean the garbage out simply lift increase the fall board gently and also wiggle it the end of place. Be careful not to bang the keys or sides of the instrument together you remove it. Right away you’ll be able to see any and everything that’s fallen into the action of the instrument.

What i do an initial is seize a dried cloth and wipe down all of the dust and loosened papers. If you desire a small hand vacuum is beneficial for blowing out those hard to reach piece of record and lint that might be in there as well.

The other location objects may have slipped down into are actually underneath the keys where the rail pins are. In this instance consider additionally removing the key slip and having a look under there with a flashlight.

Lubricating Dirty Rail Pins

The much more a piano is play the an ext maintenance it will certainly need. An regularly overlooked concern that slows down the activity and in some cases causes a key to pole is a dirty rail pin. The tricks sit on the prior rail pin which has actually a bushing top top it as well.


Over time the pin will begin to rust, so i would check that first. If you watch rust clean that off with a soft cloth, making sure to work-related away any type of debris. Simply doing that will certainly instantly free up your tricks to relocate up and also down the pin v ease. Additionally make certain to check the balance rail pins which are situated further back on each wooden expansion of the piano key.

After the rail pins space cleaned turn off it’s time to lubricate the pins. There’s every kinds that lubricant the end there, but ns personally use Protek.

If girlfriend take off the fall board you have the right to usually acquire a great look in ~ what specifically those hammers room doing.

Perhaps it’s no traveling far sufficient to the string, or perhaps the hammer elbow is relocating awkwardly. I’ve played some pianos where screws have actually fallen out of location and more too.

When it comes to anything v the hammers or really vulnerable parts of the piano I just won’t touch it. It’s simply too simple to break those parts, and they can acquire pretty expensive. It’s not worth digging within the instrument, acquisition something completely out of place and then having no ability to reinstall the properly.

Piano humidifier solution is perfect when you need consistent temperature regulation. In a warm southern atmosphere like Florida especially, a humidifier prefer this will conserve you on having to constantly track the piano, managing wood swelling and also parts obtaining messed up. For large pianos end 6′ ns recommend a humidifier system. Also if the piano is in a room with poor circulation or close to an wait vent you’ll want one of these too.
