Condensation on inside window surfaces of an insulating unit is not an indication that the glass or insulating unit is defective. Under the right set of conditions it is possible to get condensation.

Such as:

  • Inside window surface temperature falls below the dew-point temperature of the room.
  • Poor air circulation within the home
  • Room heating arrangements


  • Open your windows as much as possible to allow the humidity to escape or purchase a dehumidifier, which greatly reduces the humidity inside a home.
  • Vent clothes dryers, gas burners, etc. to the outdoors.
  • Use kitchen and bathroom exhaust fans.
  • Air out the kitchen, bathroom and laundry room during and after use by opening a window for a few minutes.Please refer to for condensation prevention tips.


Cleaning the frames and glass should only require a mild soap and water. After washing the window, simply rinse with clear water, and wipe dry with a soft cloth.

  • Do not clean with harmful cleaning solutions and abrasive compounds.
  • It's important to periodically lubricate all window tracks and rollers. We recommend that you lubricate the hardware components once a year.
  • Use exhaust fans regularly in rooms with high humidity (bathrooms, pool rooms, kitchen, etc.)
  • It's important to keep the sill or track clean of any dirt or debris.
  • Use only mild soap, water, and a soft brush when cleaning your screens. When finished rinse with clear water and wipe dry.


To clean glass, both inside and out, we suggest that you use any commercial glass cleaner or mild dish soap and lukewarm water. When finished, rinse with clear water and wipe dry with a soft cloth.

If you use a squeegee, please make sure there aren't any metal edges as this will permanently damage the Simply Clean surface and scratch the glass.


Vinyl windows are the best choice. They are easy to clean and NEVER need painting.

Periodic cleaning with a mild solution is all that is needed to keep your investment looking its best. Just wipe with a damp cloth and a mild dish soap and water solution, wipe dry with a clean dry towel and you're done! Remember not to use any type of chemicals or abrasives as this will scratch and discolour the surface.
