What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Holds more water per pass than cotton and dries faster between sessions, so it is less likely to sour sitting in a case.
Detail 02
Cut to pass through a Bb bore without wedging. Larger clarinets need a bigger swab, and a stuck swab means a trip to the shop.
Detail 03
It dries the bore. Tone holes, pads and the mouthpiece still need their own cleaning tools.
Detail 04
Microfiber sheds less than cotton flannel, so less fluff collects under keys and in tone holes.
Detail 05
Toward the top of the swab range. You are paying for the material, not a larger cloth or extra pieces.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is sized for Bb soprano clarinet. Bass and alto clarinets have wider bores and need swabs cut for them.
Every time you finish playing, and again after a long break mid-session. Standing water swells wood, shortens pad life and leaves residue in the bore.
Rinse in warm water without fabric softener — softener coats the fibers and kills absorbency. Let it dry completely before it goes back in the case.
It absorbs more and sheds less lint. Cotton still works; the difference shows up most if you play daily and the swab never gets time to dry.
