The best time to clean windows is in the spring when the elements are more likely to be in your favor, though this can vary based on where you live.
The simplest answer is you should have your windows cleaned once or twice a year in spring and fall. Most professional window washing companies will tell you the same.
Prepare for the Winter
While washing windows in the winter is possible, it's much more efficient in the fall when the weather is still warm. Prepare your windows for the cold season and forget about cleaning them until the spring comes. Ideally, you should wash your windows twice a year, in the spring and the fall.
If the weather dips below freezing, consider rescheduling your window cleaning to avoid the hassle of frozen cleaning chemicals. Otherwise, cooler temps have little impact on cleaning windows. The main thing to remember is to use cold water in cold weather and avoid washing in freezing temperatures.
Darkness and grime can interfere with the amount of sunshine that penetrates through windows. In the winter months it's even more important to ensure that as much sunshine makes it into interiors as possible so getting windows regularly cleaned is key.
Hot water cleans windows faster
Removes dirt more easily – hot water is more successful in removing dirt. This is because hot temperatures make dirt particles vibrate faster, which makes it a lot easier to wipe them away.
For residential windows, we recommend that you fully clean your windows at least twice a year, but three times a year may be best for those who live in areas with lots of trees where pollen tends to accumulate. Every six months is a good rule of thumb for window cleaning, but more often is even better.
On a sunny day, the lather will dry quickly, leaving persistent streaks and marks even after you've scrubbed and dried your windows. Window cleaning professionals recommend cleaning on a cloudy day. This weather gives you a little more time before the lather starts to dry.
In a spray bottle, combine ¼ cup of white vinegar with ½ teaspoon of liquid dish soap. Dilute the solution with 2 cups of water, then shake the bottle vigorously to mix the components. If you don't have white vinegar on hand, you can substitute it with lemon juice.
Use a cleaning solution: Like Glass-Rite cleaner! Or we also recommend a simple solution of equal parts vinegar and water, a Windex solution in water is good also. Do not use glass cleaners that are ammonia or alcohol based. They may leave streaks or make a film that attracts moisture or dust.
Optimal Season For Power Washing
A good rule of thumb is to pressure wash your house between the months of March and November. This is the ideal window of time to make sure your home is clean and protected before harsh winter weather and freezing temperatures set in.
Schmitz says that cleaning your baseboards once every two to three months should be sufficient, though that will depend on the room of your home and how much traffic it gets. If your baseboards have collected a layer of dirt, dust, and pet hair, they're due for a cleaning, regardless of when you last wiped them down.
Most people should wash their sheets once per week. If you don't sleep on your mattress every day, you may be able to stretch this to once every two weeks or so.
According to their report, windows should be washed twice a year, while screens need only to be cleaned annually. For many home owners and even renters, window cleaning usually is a once-a-year chore.
Experts agree that spring or fall is the best time to pressure or power wash your house. The goal is to avoid cleaning when the temperature is too cold or hot. The best practice is to ensure that you pressure wash your home once per year between March and November when the temperatures are not extreme.
The combination of dish soap and vinegar is highly effective for a few different reasons. They're both excellent at breaking down tough grease and grime, but vinegar alone will simply run off of most surfaces, and dish soap is too thick to use on its own.
Spray a stronger mix of 1:1 water and vinegar (or Windex, or glass cleaner) at your window, so that the solution covers most of the glass. (I found Windex to work better, but if you have pets—or kids—who frequently lick outdoor windows, vinegar may be the best route for you.)
The best way to clean windows begins with the right weather. Since bright sun will dry your cleaning solution before you can properly clean the windows and leave them streaky, it's best to wash windows on a cloudy day.
A mixture of vinegar and water can provide an effective and non-toxic cleaning solution for windows and mirrors. To clean your windows with vinegar, combine equal parts vinegar and distilled water in a spray bottle.
What happens if you don't clean your windows? "Mostly, you will slowly have less light coming into your home," Ek explains. "However, over time, a buildup of dirt particles can actually etch or degrade the glass."
Once a week at least.
Tetro says your bathroom is the ultimate bacteria host; E. coli can be found within six feet of the toilet and in the sink. To keep it at bay, disinfect the toilet and sink at least once weekly, and the bathtub every two weeks — more if you shower often.
Any high-traffic areas in your home should be wet mopped once a week. Rooms in your home that are not frequently used—such as a guest room—do not need to be mopped weekly. Mopping every other week or monthly should be sufficient.
