Industrial alcohol (meths) is the solvent/diluent for shellac, and it will soften cured shellac, and can even be used to strip a failing or failed coat of shellac. The white spots or milkiness that are the subject of this thread are, I suspect and as others have said, moisture condensing out of the air and getting trapped in the polish as it cures. Apart from setting fire to the film, one potential solution suggested, another solution might be to put some alcohol (meths) into a ball of cotton wool and wrap this is in a fairly fine lint-free cotton cloth (hanky maybe or T shirt) thus making a polisher's 'rubber'.  Then use this rubber to gently wipe over the surface a small area at a time. Basically, swing the rubber backwards and forwards so that the cotton cloth gently brushes the polish surface to soften it a bit to let the moisture out. Start cautiously, barely skimming the film surface to start with, and get more aggressive as you become familiar with how the shellac is reacting. The swinging motion of the rubber is somewhat analogous to an aeroplane touching down on the ground and immediately taking off again. Slainte.</blockquote>
