What's a better way to clean acrylic stems?

Please read rule 9! And:

Please put your location in your Profile!
Why: It will save time for others when you mention local stores, weather, tobacco prices, availability, regulations, location of photos, wildfires, air quality, etc.
How: Under your avatar, (top right, left most of three symbols) you choose "Account Details", which brings up "My Account". "My Location" is halfway down.

Neerup has a variety of brushes for the various internals of a pipe: draft, mortise, chamber, etc.
