- Frequently wash the pvc frames with warm soapy water (use a mild liquid general purpose cleaner) and wipe dry.
- In corrosive environment areas (near swimming pools, coastal, industrial etc) the frequency must be increased to reflect local conditions, and to ensure there is not a build up of corrosive deposits.
- Use only a purpose-made cream cleaner for isolated stubborn stains on white pvc. Apply with a damp cloth using minimal pressure.
- Always ensure visible drainage slots are unblocked.
- Use glass cleaner on pvc frames.
- Use excessive pressure when cleaning pvc frames, to avoid scouring the surface of the pvc finish.
- Use any types of bleach or solvent (white spirit, methylated spirits and nail varnish remover) when cleaning pvc frames.
- Use sharp edges or metallic tools.
- Use abrasives or brass cleaner on furniture (handles, doorknockers, letter plates etc.)
According to the Glass and Glazing Federation cleaning of the glass units is recommended at least twice a year, using any household non–abrasive glass cleaner or in the case of specially-treated glass, the manufacturer’s specified cleaner. A solution of warm soapy water should be used on any leaded glass surface, taking care not to disturb any glass stick-ons/bevels.
