Low-emissivity glass (AKA Low-E, e-tech, Energy Tech, Comfort Plus or Comfort Hush) differs from plain glass in that it has a very thin metallic coating on one side. This makes cleaning very difficult.
Forget harsh chemicals, the WAGTAIL E-Squeegee is designed to glide easily across Low E-Glass using your preferred cleaning solution such as detergent.
Available in 7" (18cm) and 14" (35cm) sizes.
