Excellent alternative to a washing machine professional vinyl (expensive and can cause deposits)! Here is my technique: put the disc flat, move the roller in the direction of the grooves, pressing lightly-not too much, otherwise the roller separates from the sleeve without prévenir- turn the disk of 1/8 turn and repeat the maneuver. I have found that after 5-6 discs, the amount of captured particles and significantly reduces the sticky sticky property of the roll. It is then time to move it under the water, rubbing slightly, then dry it with a towel. It then finds all its absorption quality. To the ear, the result is significant: the background noise is significantly reduced for the most dirty disks, and it is a real surprise. Please note, crunches due to scratches remain, 'do not dream!
