Pretty typical washing instructions, at least early on:
Hand wash only. Use mild soap and soft cloth in warm water less than 30cm (11 inches) deep and less than 50°C (120°F). Do not wash in dishwasher. Do not use abrasives, alcohol, solvents or harsh detergents. Do not submerge USB cable. Follow washing instructions in the Quick Start Guide.
The keys are spaced a reasonable distance apart to avoid fat-fingering and give satisfying, if not exactly IBM Model M-like, tactile feedback when struck. As a bonus, there’s a little brush clipped to the bottom of the keyboard for dusting stuff out from under the keycaps, and the USB connector on the cord has a tethered cap to cover it when you’re giving it a scrub in the sink.
Costs about as much as three crappy keyboards you’ll throw away in six months.
