I think you can only get the strips on the tube. You just chuck the tube when its unusable. Here are two tips. First you can clean them with laudry detergent and a brush. Second you should clean really dirty records in two steps, and you should use a different tube for each stage. Since the tube for really dirty records will leave dirt on the pads, you don't want to pass this dirt on to another record. When I was really fanatical in the 70's, I had a four bath system for cleaning and only the absolute dirtiest records were ever sponged.
