uPVC shutters are designed to be very low-maintenance.
Day to day, you only need to dust the slats regularly with a soft cloth, feather duster, or microfibre wipe. For a deeper clean, a damp cloth with mild soapy water is all that’s required, and you should avoid abrasive cleaners or strong solvents, as these may damage the painted finish.
Since they are fully waterproof, they can be safely used in kitchens and bathrooms, but it is still a good idea to wipe away any excess condensation or splashes to keep them looking fresh.
The hinges and tilt rods usually need no attention, but if they ever become stiff, a small amount of silicone spray will keep them moving freely, and screws or fixings should be checked and tightened occasionally.
You should also avoid forcing the slats beyond their natural movement, and if your shutters have a central tilt rod, always open the panels from the frame edges rather than pulling on the rod.
With this simple care, uPVC shutters will not warp, crack, or fade and should remain in excellent condition for many years.
