if you mean a cleaner for the lens then yes there are ones with little brushes on them for this purpose. normally these are fairly cheap, $5-10 or so. if you have a higher end player you might want to try this first. if you have a cheap player than replace it with another cheap player under $20. it might be dirty or it might be a real problem, hard to tell without trying. cleaner does work (well its alcohol based i think) and i've used it in the past on some different players with success. just make sure that your particular player is okay with using them...
