How to Maintain Your Secondary Glazing

Cleaning Glass

Soft, lint-free cloth and standard glass cleaner. Apply to cloth, not directly to glass. Wipe in circular motion. Buff dry. No abrasive cleaners.

Cleaning Acrylic

More care needed — acrylic scratches more easily. Use specialist acrylic cleaner or mild soap solution. Anti-static cleaners (e.g. Burnus Antistatic) recommended to reduce static dust attraction.

Cleaning Aluminium Frames

Damp cloth and mild detergent. No harsh chemicals. Dry with soft cloth. Powder coat finish requires no waxing or sealing.

Maintaining Seals

Woolpile seals last many years but will eventually compress. Signs of wear: increased draughts, reduced noise reduction. Replacement seals are inexpensive and easy to fit.

Maintaining Sliding Mechanisms

Clean track to remove dust and debris. Light application of silicone spray if sliding becomes stiff. Do not use oil-based lubricants — they attract dust.

Maintaining Hinged Units

Operate handles regularly to prevent stiffening. Occasional light lubrication of hinge pins. Check multi-point locking engages correctly.
