What maintenance is required for OKNOPLAST windows?

OKNOPLAST windows are designed to be low maintenance and long-lasting. Thanks to the use of high-quality uPVC and aluminum, they’re naturally resistant to warping, discoloration, and weather damage.

To keep your windows in optimal condition, we recommend the following care routine:

• Frame cleaning: Use mild soap and water to clean uPVC or aluminum frames. Avoid abrasive cleaners that could damage the surface.
• Glass care: Use standard glass cleaner and a soft cloth for streak-free shine. Avoid using scrapers or rough sponges on the glass.
• Hardware maintenance: Once or twice a year, apply a small amount of lubricant (like silicone spray) to the moving parts and locking mechanisms to ensure smooth operation.
• Seal and gasket check: Inspect seals and gaskets annually for wear or dirt buildup. Clean them gently with a damp cloth to maintain tightness and insulation.
• Seasonal inspection: Before winter and summer, check all windows for proper closure, drainage holes (weep holes) for blockage, and ensure all components are functioning smoothly.

Following these steps helps ensure your windows continue to deliver peak performance for years to come — with no need for painting, staining, or intensive upkeep.
