Cleaning of Glass

This information is provided as a general guide only. Specific advice on the cleaning of glass should always be obtained from either the supplier or a professional window cleaner.

Special Products

The Solarplus, Optilight and Solect range of glass products have high performance coatings applied to their surfaces, consequently these products require a more specialised cleaning procedure. Mirrors also require a more specialised cleaning procedure.

Routine Cleaning Instructions

Glass products must be properly cleaning during both construction activities and as part of routine maintenance in order to maintain visual and aesthetic clarity. Improper cleaning can permanently damage the surface of glazing products.

Cleaning of the glass should begin at the top of the structure and continue down towards lower levels to minimise the probability of leaving cleaning residues on the lower levels. Care should be taken to prevent wind blowing residues onto glass that has already been cleaned.

The glass should only be cleaned when cool to touch and should never be cleaned while in direct sunlight.

  1. Completely drench the glass with clean water to loosen any residues, deposits or dirt.
  2. Spray one of the recommended cleaning products (mentioned below) onto the glass surface.
  3. Immediately remove the cleaning solution with a lint free cloth.
  4. Any stubborn dirt should be lightly sponged off, being careful not to scratch the glass. All traces of water and cleaning solution must be removed from the glass, window frames and also from any sealant or gaskets present. Failure to remove any residue may cause these components to deteriorate as a direct consequence of the cleaning process.

High Performance Coated Glass

Solect, Optilight and Solarplus

Introduction

G.James' range of high performance monolithic and laminated glass products are characterised by their outstanding thermal insulation and solar control performance. To achieve these qualities, a microscopically thin coating has been applied to the interior surface of these products. While these coatings are extremely hard and durable, they require modified handling, cleaning and maintenance compared to traditional glazing products.

Cleaning Instructions - Exterior Surface

Cleaning of the exterior surface may be carried out as per the routine instructions above.

Cleaning Instructions - Interior Surface

As the interior surface of these high performance products contains a microscopically thin coating, a different cleaning procedure is necessary. While the recommended cleaning solutions are the same as detailed above, G.James advises that the coated face be hand cleaned - the use of squeegees is not recommended.

Mirrors

Mirror Cleaning Instructions

The surface of mirrors requires special care when cleaning. It is particularly important to ensure that there is no contact between the mirror backing material and the cleaning solution - particular care should be taken to prevent contact at the edges of the mirror. If the backing material is contacted with the cleaning solutions irreversible degradation of the mirror may result.

The mirror should only be cleaned when cool to touch and should never be cleaned while in direct sunlight.

To clean the mirror place a few drops of methylated spirits onto a clean, damp cloth. Wipe the solution over the surface of the mirror. Polish the surface dry with a clean, dry lint free cloth.

Frequency of Cleaning

Cleaning required is dependant on the severity of the environment. The following time periods represent a guide only.

Rural / Suburban Environments

The maximum period between cleaning should never be more than six (6) months.

Coastal / Pool / Industrial Environments

More frequent cleaning is necessary here with the maximum period between cleaning being no more than three (3) months.

Extreme Conditions

Under the worst conditions involving heavy grime deposition and atmospheric pollution (e.g. sulphur compounds or salts) monthly cleaning is advisable if deterioration is to be prevented.
