General advice for all makes and types.

• Do not use oil to lubricate squeaky hinges (or any nylon moving parts), use a furniture aerosol wax spray instead, which contains silicone.
• Once a year clean and light oil visible moving metal parts, particularly door locks and 'friction stay' window hinges.
• Never allow the use of washing up liquid in the water when your windows are cleaned - it attacks and degrades the seals.
• Use a generous squirt of cream cleanser in warm water to spring clean white PVC-U, (no abrasives should be used on woodgrain).
• Keep sliding Patio Door tracks brushed clean of mud, grit and dust. Do not lubricate the track.
• Make sure there is a key in each room for undoing security-locking windows in the event of an emergency.
