after getting ragged off with the cd player skipping at every single bump on the road i whipped it out took all the covers/plates off the cd player so i could see the laser and cleaned it with a cotton bud with a bit of my wifes facail pore cleaning stuff thats got a high% of alcohol then cleaned it with a couple of dry cotton buds put it back together and took it for drive for 10 minutes actually looking for pot holes and success not a single skip on the cd , saved myself a few quid there as i was going to get a new cd/radio , tight as a duck's arse me
