Has anyone ever tried compressed air? I've been giving it thought, as I'm currently half-heartedly engaged in digitising LPs to CD, and I have about 300+ to go! I have a compressor, and as far as I can see it should work well, as the air is clean and you can vary the pressure. Would pay to soften the dirt with detergent first, I should think.

If anyone's tried it, I'd like to know. Failing that, I'll try with one of the LPs I don't like.   Trouble is, I've not played those ones much, so they are in pretty good condition. Have to buy one from a junk shop.
Using 'LP Recorder' from a cover-disk, and 'Nero 6', and an Optimus LAB1100 turntable. Cheap and good enough, as far as I can hear. Diamond stylus, built-in pre-amp.
