Window maintenance: simple steps for durability

How to keep windows like new: cleaning the profiles, lubricating the hardware and caring for the seals.

Quality joinery lasts for decades, but a few simple actions, once or twice a year, extend its life and keep it working perfectly.

Recommended routine

  • Clean the profiles with a soft cloth, lukewarm water and a non-abrasive detergent (no solvents)
  • Lubricate the hinges and locking mechanisms with fine-mechanism oil once a year
  • Treat the seals with glycerine so they stay elastic
  • Clean the drainage channels at the bottom of the frame once a year
  • Remove the protective film within 3 months of installation
