LAST Stylus Cleaner safely removes accumulated stylus deposits that come from organics, pollution, dust, pets and fingers. A dirty stylus changes music into noise, wears faster, and tracks poorly. To hear your music, not your dust, and to extend the life of your cartridge, keep it clean. Use before each play or whenever you hear noise or distortion from accumulated contamination. The built-in brush is impossible to lose and effective at safely reaching your stylus. Safe for all cartridge assemblies, and each bottle contains enough formula for hundreds of cleanings.
