Low ‘E’ Glass has a thin coating to the inner face of the glass. It is this hard and durable coating which gives the glass its thermal insulation and solar control performance compared to ordinary clear glass. The coated surface of Low ‘E’ glass does not need to be cleaned differently to ordinary glass and the following guidelines are recommended for the best hand cleaning results.
Hand cleaning of the coated (interior) surface of the Low ‘E’ glass to visibly remove accumulated dust or fingerprints, can be accomplished using a number of different glass cleaning products. The exterior surface of the glass is not coated and can be cleaned in the same fashion as ordinary glass.
A mixture of one part vinegar with ten parts water Vinegar based glass cleaners have generally demonstrated an ability to provide a clean and streak free glass surface. Do not use ammonia based or alcohol based glass cleaners because these cleaners tend to leave visible streaks.
Flood the glass surface with the spray on cleaning solution or with a cloth saturated in cleaning solution. Be generous with the amount of solution applied.
Scrub the wet area with a clean, lint-free towel or cloth.
Wipe dry with a dry, clean lint free towel or cloth. DO NOT USE A SQUEEGEE on the Low’E’ coated (interior) surface.
To prevent streaking, stop wiping when the glass is almost dry and there is a uniform film of moisture left on the glass surface.
Under no circumstances should razor blades or squeegees be used on the low E coated (interior) face of the glass
