Glass Cleaning Instructions:
Cleaning the glass in your windows and doors should form part of a regular maintenance routine. As it is important to preserve the clarity and performance of your glass, any deposits or dirt on glass surfaces should be promptly removed. Improper cleaning practices can permanently damage the surface of glass.
Glass should only be cleaned when cool to touch and should never be cleaned while in direct sunlight.
- Completely drench the glass with clean water to loosen any residues, deposits or dirt.
- Spray one of the recommended cleaning products (mentioned bellow) onto the glass surface.
- Immediately remove the cleaning solution with either a squeegee or a lint free cloth.
- 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 as well as any sealant or gaskets present. Failure to remove any residue may cause these components to deteriorate as a direct consequence of the cleaning process.
- Do not use metal scrapers, blades or steel wool on either surface of the glass.
- Do not allow water or cleaning fluids to remain in contact with the glass, frame, sealants or gaskets for long periods.
- Do not use abrasive cleaning solutions or materials.
Cleaning Products Recommendations:
- A solution of 1 part vinegar to 10 parts clean water, or
- Windex® Multi -Surface Cleaner (colorless) (manufactured by SC Johnson and Son Pty Ltd).
- CRL Hi -SHEEN® Glass Cleaner
- CRL 150 Lint – Free Wipes
Note: Do not use the blue colored Windex® product.
Special Instructions for Low E Glass
The interior surface of the Low E (or metal based) coating requires appropriate care when cleaning. While the recommended cleaning method is the same as for other glass, Step 3 (above) requires the interior, coated surface be hand cleaned with a soft lint free cloth only.
Spot Cleaning Stubborn Dirt & Residues (applicable to all glass types)
Acetone is the recommended solvent for the removal of stubborn dirt and other residues such as oil, grease, tape residues and the like from glass surfaces. Acetone is available from most hardware stores and always follows the manufacturer’s safety and handing recommendations.
Spot cleaning employs a simple; two-cloth method where one cloth is used to break up the dirt /residue and a second cloth is used to remove the residue from the surface.
- Apply a small amount of acetone to a clean, slightly damp cloth.2.
- Rub this cloth onto the affected area.3.
- Use a second lint free cloth to remove the residues from the surface.4.
- The entire surface should now be cleaned as per the regular cleaning procedure to eliminate streaking.
It is important that the frames, sealants and gaskets are protected during spot cleaning as Acetone and other such solvents can cause irreversible degradation of these components.
Frequency of Cleaning
Cleaning required is dependent 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.
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.
