If you're deciding between a general instrument polishing cloth and a clarinet-specific bore swab, you're really choosing between two different cleaning jobs. The Durable Sky Blue Polishing Cloth for String Brass Woodwind Instruments Cleaning is listed at USD 17.02, while the On-Stage Synthetic Clarinet Swab is listed at USD 35.54. One wipes surfaces; the other clears the inside of a clarinet bore. The right pick depends on whether your instrument needs a quick shine or a thorough dry after playing.
Quick verdict
Reach for the sky-blue polishing cloth if you play a mix of string, brass, and woodwind instruments and want one cloth for surface dust and fingerprints. Reach for the On-Stage synthetic clarinet swab if your clarinet bore collects moisture and you need a dedicated cleaning tool with a weighted string.

Where each product stands out
Surface cleaning with the sky-blue cloth
The polishing cloth is positioned for string, brass, and woodwind instruments, and the product description mentions reaching intricate spaces on violins, guitars, and saxophones. Its compact size of 10.00 x 5.00 x 0.10 cm makes it easy to carry in a case, and the cloth material is listed as the cleaning surface.
Bore cleaning with the On-Stage swab
The On-Stage swab is described as a durable synthetic swab with a weighted string, which is useful for pulling moisture through a clarinet bore. It comes in black and is listed as new. This is a targeted piece of cleaning gear for players who want the inside of the clarinet addressed directly.
Product notes
Durable Sky Blue Polishing Cloth for String Brass Woodwind Instruments Cleaning

If you own several instruments, this cloth is the broader solution. The description calls out versatile application for violins, guitars, and saxophones, and the small 10 x 5 x 0.1 cm footprint fits easily in most gig bags. Described as gentle yet efficient, it aims to deliver shine and cleaning in one step. The cloth is intended for surface shine, not bore work, so it leaves the interior of a clarinet untouched. If your only cleaning concern is a dusty wooden or metal body, this cloth gives you one simple accessory for multiple instruments.
Synthetic Swab for Clarinet Bore Cleaning - On-Stage

When the inside of your clarinet needs attention, the On-Stage swab is purpose-built for that task. It includes a weighted string, which helps pull the synthetic material through the bore, and the product color is black. The manufacturer describes it as a durable synthetic swab, and the package quantity is one, so you're getting a single go-to cleaning accessory. It's a dedicated clarinet tool, so it doesn't replace a general polishing cloth for finger-printed brass or varnished wood. If you're a clarinet player who finishes every session with a damp bore, this swab is the more direct instrument.
Final choice by use case
Choose the polishing cloth when you want one cleaning cloth that covers multiple instruments and you're focused on surface spots and fingerprints. Choose the On-Stage swab when your clarinet's bore is the area that needs a reliable dry. If you only buy one accessory, decide which job happens more often: the outside wipe-down or the interior bore clean.
