Plexus(c) Plastic Cleaner is specially developed for the aviation industry for cleaning and protecting aircraft windshields. Plexus can also be used on virtually any variety of plastic surfaces. Plexus is an effective solution to clean, protect, and polish all types of plastics. Using Plexus is easy to use — simply spray and wipe with no buffing, mess or waste. Plexus works by sealing the pores within the plastic surface with a thin layer of protective wax to resist debris, oil, dust and lint, and yellowing. Plexus does not leave smears or smudges; instead it leaves surfaces with a lustrous finish — colored plastics are made vibrant and clear plastics become virtually transparent. This product (EDMO# 20207) is a 7 oz aerosol can.
