My idea is to make small stand alone washing machine (about the size of a toaster oven), to be set on a counter top and plugged into the wall. It would have a removable basket in it, that the nebulizer cups would fit into but be able to move around a little. It would also have a small removable water canister that can be refilled when empty. It would have different water jets that spin around and such, and an internal water heater to help kill bacteria, and also an internal soap dispenser. Most of the water used would be re-circulated to save water.

This would also work with small dishes like, 5 mugs, or couple plates/bowls or, some utensils etc.

So, many people could use this, not just people with nebulizers.

And people like me would do their treatments as often as they're supposed to.
