Care & Maintenance

Constructed from Architectural Grade Aluminium and 316 Stainless Steel Mesh, both of these metals are highly corrosion resistant and exceptionally strong. With a moderate amount of maintenance, your Invisi-Gard® Stainless Steel Security Screens will retain their good looks, and resist the elements for years to come.

Invisi-Gard® Stainless Steel Security Screens are the product of years of development and are designed to resist corrosion and rusting, but as with all external fixtures on your home, they require some maintenance to keep looking good and performing well. Depending on how harsh the environmental elements are, the maintenance period will vary. Refer to the suggested maintenance table.

Your Invisi-Gard® Stainless Steel Security Screens should only ever need to be washed down with a soft bristled brush using warm mains water and a mild detergent.

Rinse well with mains water to remove any detergent residue paying particular attention to ensure ALL residue is flushed from the mesh retaining areas of the frame.

Only mains water is to be used as recycled, bore or tank water is unacceptable and may lead to detrimental corrosion effects. Care should be taken to avoid excessive amounts of water entering the main lock and auxiliary 3 point locks.

Strong detergents and abrasive cleaners MUST NEVER be used to clean your Invisi-Gard® Stainless Steel Security Screens as these may scratch or damage the surface finish and increase the likelihood of corrosion.

Periodic lubrication of the main lock and auxiliary lock components should only ever be done using graphite powder. Liquid or aerosol lubricants can cause corrosion and damage the locking mechanism.

External contaminants that come into contact with the Invisi-Gard® screens such as bird and bat droppings are very acidic and can quickly burn and damage the powdercoat finish of the frame and the mesh coating.

To ensure the Invisi-Gard® warranty is maintained, it is essential that these external contaminants are cleaned immediately with a mild detergent, soft bristled brush and rinsed thoroughly with mains water.
