The best thing is for your clear enclosure is boat soap and water with a wash mit. Always chamois after to avoid water spots. Occasionally we clean all of our enclosures with a microfiber and enclosure cleaner only like Plexus, 210, or Aquatech, followed up by a coat of Collinite's insulator wax. That's it! No harsh chemicals or aggressive polishes or cleaners. If it needs to be restored beyond that consult a professional detailer. Don't forget to use snap and zipper lube to keep them from corroding or locking up.
