How do you clean your skylight?

Advice for the Maintaining and Hand Cleaning of All Atlite Glass Skylights


This glass product has a very thin coating on the interior glass surface. It is this hard and durable coating which gives the product improved thermal insulation and solar control performance compared to ordinary clear glass. The coated surface of the glass does clean differently to ordinary glass and these guidelines are recommended for the most appropriate hand cleaning results.

Routine Cleaning

Hand cleaning of the coated (interior) surface, 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 so can be cleaned in the same fashion as ordinary glass.

Recommended Routine Cleaning Products

  • Windex® Multi-Surface Cleaner (colourless liquid) (Australia) or Mr Muscle® Surface and Glass (New Zealand) (clear liquid available from Supermarket),
  • produced by SC Johnson & Son Pty Ltd
  • A mixture of one part vinegar with ten parts

In addition to the above products, commercially available vinegar-based glass cleaners have generally demonstrated an ability to provide a clean, streak free glass surface.

Viridian does not recommend the use of ammonia-base and alcohol-base glass cleaners because these products tend to leave visible streaks.

Routine Cleaning Procedure

  • While cleaning ensure jewellery and watches are removed and gloves should be worn.
  • Flood the glass surface with the spray-on cleaning solution or with a cloth saturated with the cleaning Be generous with the amount of solution applied.
  • Scrub the wetted surface with a clean, lint free towel or
  • Wipe dry with a dry, clean, lint free towel or cloth. Do not use a squeegee on the coated (interior)
  • To prevent streaking, stop wiping when the glass is almost dry and there is a uniform film of moisture left on the glass surface. The film will quickly evaporate leaving a clean surface.

Spot Cleaning

Occasionally spot cleaning may be required to remove stubborn dirt or foreign materials which adhere to the surface. Spot cleaning products work to remove markings from grease, oil, tape adhesive, and crayons or other waxy materials as well as paint and rub-off marks from plastics.

Do not use razor blades, steel wool, scouring bristles or other metallic or abrasive objects on the coated surface.
