Cleaning and Maintenance

When & Why

External Surfaces:

If the windows or doors are in direct influence of salt water, industrial chemical plants, blast furnaces or other aggressive emission sources then they should be cleaned at least every three months. In a relatively cleaner environment every six months should be sufficient.

Internal Surfaces:

Over a period of time grime and deposits can gather and discolor the frame. Cleaning at least once per year is recommend to keep your frames at there best.


• Clean warm water containing a non-alkaline liquid detergent (concentration safe enough to use bare hands).
• Non abrasive cloth, sponge or soft bristle brush.
1. Clean all areas of the frame including ridges, groves, joints and drainage channels to remove grime, grease and any excess chalking.
2. Rinse thoroughly with clean water.
3. Dry using a soft cloth or leather.


• If a reduction in gloss, chalking or excessive staining has occurred then use an approved renovating cream with a non-abrasive cloth. (i.e. T-cut). NOTE: Care must be taken not to abrade sharp corners or aris of bead to heavily where the paint film is normally thinner. Don’t carry out to frequently.
• For extra protection a wax polish can be applied with a soft cloth, up to twice yearly, to restore glass.
• It is recommended to check cut joints and re-seal as required to prevent water ingress. This should be done periodically.



• Blisters and corrosion sites may originate from areas where mechanical damage or scratches have penetrated the paint coating through to the aluminum. (i.e. mitres and drill holes). This leaves the aluminum unprotected.


1. Use fine grade 120-360 grit abrasive paper to remove corrosion products or non-adherent paint.
2. Wipe with a cleaning solvent (i.e. white spirit) and leave to dry.
3. Once completely dry apply a thin priming coat using a fine brush. Allow 20-30 mins to 'flash off’.
4. Touch in with air drying paint using a fine brush. NOTE: Air drying paint will not possess the same weathering as the original stoved organic coating but will give a reasonable amount of protection. Only use on small areas of damage.
