AY-AE、SY-AA、SY-BA 專用小清潔刷

The cleaning bristles are stiff enough to get into the tiny crevices around the battery compartment without scratching anything. I've been using it weekly and it keeps the contacts clean with zero fuss.

Honestly wasn't expecting much from a tiny replacement brush, but this one feels sturdy enough for regular cleaning and the bristles get into the tight gaps without shedding. Took a few seconds to swap out the old one, and now my unit's back to working like it should.

This little brush fits my unit perfectly and has held up through daily scrubbing without shedding a single bristle. It's compact enough to reach the tight corners I couldn't get to before.
