This really works! If your record collection has had a hard life, or you regularly buy secondhand vinyl, you need one of these. Can transform previously unplayable records. When I first got hold of one of these I was amazed that records I thought were worn out actually just needed a good clean. Radically reduces surface noise and improves the sound of dirty vinyl all round.
While the Knosti is not quite as effective as a professional record cleaner it’s better than any DIY method we’ve found. Strongly recommended!
