Care and Maintenance Advice
General Aftercare
- uPVC, Aluminium, Garage Doors and Glass: Clean with mild detergent and soft cloths. Avoid abrasive cleaners or ammonia-based products. Take care to remove grit or debris before cleaning.
- Locks and Hinges: Lubricate annually with white grease or light machine oil.
- Cylinder Locks: Use graphite lubricant only. Do not use penetrating oils or multi-purpose lubricants such as WD-40, as these can damage the internal mechanism and attract dirt.
