Is there a way to clean windows in winter when it's below freezing outside?

Yes, you can clean windows in winter below freezing, but it requires special techniques and products to prevent the cleaning solution from freezing on the glass.

The key is using an alcohol-based cleaning solution that won't freeze at typical Ottawa winter temperatures. Mix one part isopropyl alcohol (70% or higher) with two parts water, plus a small amount of dish soap. This solution will remain liquid down to about -15°C to -20°C, covering most winter cleaning situations in Ottawa.

Work quickly and strategically when cleaning in freezing weather. Start with the exterior windows on the sunny side of your house when possible, as direct sunlight helps prevent immediate freezing. Clean one window completely before moving to the next, and use a squeegee to remove the solution quickly before it can freeze on the glass. Avoid cleaning during windy conditions, as this accelerates freezing and makes the work more difficult.

For interior winter cleaning, focus on removing condensation buildup and salt residue that accumulates from heating systems. This is actually more important in winter since poor indoor air quality and humidity issues become more noticeable. Regular interior cleaning also helps you spot any air leaks or seal failures that might need attention.

Consider your safety first - icy conditions make ladder work dangerous, and extremely cold temperatures (below -20°C) can make the work uncomfortable and potentially harmful. If you have older windows with compromised seals, winter cleaning might reveal issues like condensation between panes that indicate it's time for replacement.
