WHY THE VINYL CLEANER PRO GREY - Offers a sophisticated technology combined with maximum ease of use and little time and effort, so that you can relive music. IT'S SIMPLE TO USE - The LP is placed vertically into the device from above, after pressing the start button the Vinyl Cleaner starts cleaning independently. HOW IT WORKS - The ultrasound sets in and vibrates the cleaning solution to loosen the dirt from the depths of the grooves, while four microfiber cleaning rollers drive to the LP and gently remove the previously loosened dirt from the LP by rotating in opposite directions. WHAT ABOUT VERY DIRTY LPs - The standard washing program can be extended from 1.5 to up to 5 minutes. INCLUDES: A fabric cover and the cleaning concentrate (2 vials included), which contains no alcohol and is biodegradable. It also contributes greatly to reducing the static on the LP.
