uPVC requires little maintenance but to ensure you get the best from your Windows and Doors please follow these simple steps:
Frames should be cleaned regularly with soapy water; ordinary washing up liquid is fine. If dirt is really stubborn you can use a non-abrasive household cleaner or neutral car colour restorer, which should then be washed off with soapy water.
Do not use abrasive cleaner or wire tool as this will damage the surface of uPVC.
You should lubricate all moving parts at least twice a year. Stainless steel hinges should be oiled at the rivet points with light silicone lubricant. Other metal components should be coated with petroleum jelly.
Do not use spray oil or excessive lubrication.
Make sure Windows and Doors are fully closed before operating handles. This will avoid straining the lock mechanism.
Do not force handles or locks. If they will not operate, check there are no obstructions and try again.
To minimise the risk on condensation, you should open windows in each room for a short time each day.
