Cleaning windows on a sunny day can be a challenge, as bright sunlight highlights dirt and makes the task more difficult. Direct rays can cause cleaning products to evaporate rapidly, leaving unsightly streaks and potentially damaging the glass. Applying cold water to extremely hot glass can trigger thermal shock, which may lead to cracking.
Experts Advise Against Cleaning in Direct Sun
Cleaning expert Lynsey Crombie recommends avoiding window cleaning on bright days. Her guidance is to tackle exterior windows only when they are shaded and to use warm, soapy water. Window-cleaning professional Jake Lucero, who operates Pink's Window Cleaning, also weighed in on the discussion, noting that cleaning in direct sunlight can be "tough".
In a TikTok clip, Lucero explained: "You can, but it is definitely hard. The reason being is that we use water and dish soap to clean windows, so if the glass is super hot it dries really fast, leaving streaks before you have even squeegeed it." His tip is to clean windows in the shade and during cooler parts of the day so the glass isn't too hot. In his caption, he added: "This will allow you to actually clean the windows before the soapy solution dries."
How to Clean Windows Effectively
Lynsey shared her technique for cleaning windows when they are not in direct sunlight. She recommends that warm, soapy water "works best". After preparing the solution in a bucket, take it outdoors. Begin by brushing off any cobwebs or dirt from the window surface.
Dip a cloth into the bucket of soapy water and begin wiping the glass from the top downwards using circular movements. After the entire window has been cleaned, use a squeegee or window vacuum to remove the water. Lynsey always ensures she wipes horizontally along the window's base to clear any water that gathers there.
Alternatively, you can use a crumpled sheet of newspaper to soak up any remaining moisture and achieve a polished finish.
