Is it Worth the Risk...hmm

Either side would drip onto your hand. Not convenient enough.

Oh, I don't think it'd be that expensive...

It's fine if you wear gloves. I have a pair of ski gloves that are perfect for toilet cleaning, warm yet absorbent!

I'll pass, I use a plunger more than a brush anyhow.

If the plunger is detachable, then you could use one, and then let the other side dry out first.
