For sparkling luminous crystal items, spray each piece until dripping wet, then leave to dry! Specially designed for cleaning crystal light fittings, as well as a host of other fine crystal pieces such as vases and ornaments, my wonderful Luminous Spray will restore a brilliant sparkle and add a special radiance to all manner of crystal items.

All one has to do is spray each item until it is dripping wet, and then leave it to dry. I doubt you'll find an easier way of shedding so much light!
