This is a great value set for LP (10-12 inch) and EP (7 inch, donut-shaped) records, highly acclaimed by record collectors and DJs who prioritize sound quality. Records that haven't been played in a while, or those purchased from bargain bins, can often have dust, debris, or mold in the grooves. This can result in hum, crackle, popping noises, or even skipping, making them unlistenable. The general cleaning method for records involves using a record cleaning solution and brush, which often works well. However, over time, these can deteriorate, leading to further buildup in the grooves. The best cleaning method involves soaking the record in water mixed with a neutral detergent, and then using a fine, soft brush or melamine sponge that won't scratch the record to remove dust, debris, and dirt from the grooves. The biggest challenge during cleaning is preventing the record label from getting wet. This product protects the record label while you clean. The product is easy to use, and an instruction manual with usage instructions is included. Please read it and follow the instructions. Blend Dizzy Records
