For sake of clarity, when i mentioned "air drying" the disc, i didn't mean to apply the solution and let it dry on the disc via exposure to air. I meant that one should clean the disc as one normally would i.e. applying the solution and removing it as best possible and THEN letting it air dry. My thoughts about this were that if someone were to clean the disc and then put it back into a sleeve while still damp / wet, "bad things" might happen. A paper sleeve could bond to the moisture and / or a plastic sleeve could trap the moisture, producing what would probably be a warm, dark, moist area for bacteria to grow. Allowing the disc to dry thoroughly prior to inserting it back into the sleeve would remove any chance of either of these happening. By no means did i mean to leave the solution & "crud" on the disc to dry by the air. Sorry if this caused any confusion. Sean
