Cleaning Tip

We have 3 smoke detectors in the house. Basement. First floor. Second Floor.

One of them is new. Why? Well... I was cleaning the one from the first floor, and I dropped it in the sink... and it landed in a bowl full of water.

After that, it didn't work.
In fact, it simply went berserk,
beeping till my ear
could barely hear.

So, here's my cleaning tip:
don't let such gizmos slip
into anything wet.
They just get upset.
