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.
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.
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.
