It's not often something people forward me makes me _literally_ LOL, but this did it.
@voltronic Well it looks like composer is at least getting most of the keyboard clean. 🤪

I actually tend to omit the first 6 measures when I "perform" this.
Then I play it again, in retrograde.

I feel I should put two warnings out there about cleaning piano keys:
1. I would not wipe horizontally (like the glissandi shown in this funny piece) because you could get moisture and dirt falling between the keys into the keybed. That would be bad.
2. On plastic keys, you're probably ok with disinfectant wipes. For real ebony and ivory, you only want to use a white cloth dampened with warm water and mild dish soap.
