DS Audio first accessory, the ST-50 Stylus Cleaner utilizes a specially designed Urethane gel, the same gel used in the industrial-grade clean room conditions. The Urethane prevents dust from entering the clean room by absorbing it in the micro level. The high-quality aluminum material used for the casing features a nickel plated surface. Real leather is used on the base of the casing for no damage to your platter.
"To use, simply remove the cover, carefully place it on the platter and gently lower the arm onto the pad, lifting and lowering a few times after which the stylus should be 100% dirt and dust free without the use of brushing or potentially dangerous liquids. Some manufacturers that use cement to bond styli to cantilevers, such as Ortofon specifically recommend against using solvent based liquids that can dissolve the bonding material. ...if you care at all about design elegance as well as effective stylus cleaning, the DS ST-50 is the ticket." - Michael Fremer, analogplanet.com
