Using the Audio - Technica AT617A cartridge stylus cleaner is a breeze. Just lower the stylus onto the gel, and it'll start removing dirt from the tip. It's that simple! When it comes to maintenance, since the gel's surface is washable, you can clean it with a mild cleaner whenever it gets dirty. This way, you can keep using it for a long time. As for precautions, avoid touching the gel with your fingers too much as the oils on your hands might affect its tackiness. Also, store it in a cool, dry place when not in use. That's all you need to know to keep your stylus clean and your records sounding great!
