I leave mine open all the time and it doesn’t seem to gather a lot of dust. Of course M&H are heavy as lead, and opening and closing the lid (5’8” piano) takes some strength. Additionally, keeping it open keeps the cat from jumping up on it, and keeps guests from thinking it’s ok to set a drink on top of the piano.

I used to keep it on the short stick to reduce sound, but read that may contribute to warping, so now it’s always on the long stick.

So, for me, open is better. It is hard to reach in some places to dust, but a feather duster helps. We have a Roomba that runs daily so there’s not much dust in the room.

I always keep my AF215 completely closed with a fitted string cover so no dust seeps in from the gap between the lid and rim when I'm not playing it.

@ Learux - I recall that your AF215 had a fitted string cover when I auditioned it last January, sometimes I play with mine still in place. Still looking forward to additional photos and hope you are enjoying the instrument.

If short stick may contribute to warping, why wouldn't full stick do the same?

It has to do with physics. There is much less gravitational pull/stress on the lid when on the tall stick/prop. Take a piece of 4'X8' plywood and prop it up at a 45*/50* angle and notice the bow/warpage of the plywood. Next, prop up the sheet of plywood at a smaller angle, say 20*/25* and notice the warpage/bow.

I know the lid of a grand piano is thicker than a sheet of plywood, usually, (depending on the plywood) but the principle is the same.

I've seen noticeable lid warpage on grand pianos whose lid is left propped on the short stick for long periods of time. I'm sure there could be some warpage on the piano lid left propped on the tall stick/prop for long periods of time, but short stick/prop will lead to lid warpage much faster.

Also, the material the lid is made of can affect warpage to an extent, but the results will still be the same over a period of time. A good quality lid material will likely warp much slower over time. Cheaper, heavier (MDF) lids will warp faster.

Removing the lid prop and closing the lid when not playing will help prevent warpage, whether on the tall prop or short prop.

Just my .02.

Like and unlike some others, I

- live in a house that doesn't generate much dust,
- clean regularly
- never completely close the piano; doing so sends the message: "Don't touch me!"
- leave the fallboard up and the music stand up
- use a string cover inside the piano
- occasionally remove the string cover and vacuum it (top surface only, of course)
- don't have appreciable dust on the soundboard, my tech will occasionally vacuum when the action is out
- occasionally play on half-stick, but mostly with the lid down.

It seems to have worked for me for over 14 years.

Regards,

j&j, can you link the one you have?

Do you use it for under string dusting as well.

I don't have a lot of dust laying around just want to be pro active here.

Sorry. I just use a regular single extendable Swiffer duster with clean Swiffer dusters separate from the Swiffer dusters I use for other furniture. It’s my “piano Swiffer”. I gently use it on top of the strings and the plate and exposed areas of the soundboard.
