Dupont Sontara brand aerospace wipes provide cheap protection for those expensive aircraft windshields.Specifically designed for aviation manufacturing and maintenance, these wipes are made of a unique blend of fibres manufactured in a process that creates a low-linting fabric resistant to snagging and fraying. Since many scratches are caused by grit and dirt already on the window, not the wipe, this product features apertures that help pick up and remove dirt effectively, and yet are softer than most conventional wipes.Sontara window wipes are exceptionally clean and contain no added chemicals or binders. These versatile wipes can be used on cockpit transparencies, passenger windows (both interior and exterior surfaces) and other acrylic, polycarbonate or glass surfaces on board the aircraft. We think youll agree that these wipes are tough on dirt, but soft on those expensive windows and other sensitive surfaces. Put them to work for you.100 wipes per pack. Measure 12" x 12".
