Window Cleaning In the Sun
“Never clean windows in the sun!”
- That’s the advice given in many housekeeping magazines. But is that true?
For the general householder it is good advice, but a professional window cleaner cannot afford to be always dictated to by the weather.
Especially when using traditional methods, cleaning in the hot sun can cause problems so here are some tips to avoid the smears and shadows.
Shadows left on the window are caused by the solution drying before the squeegee blade carries it away.
On overcast days you may mop a few windows at a time and a few minutes may pass before you squeegee them all clean. However, when the weather is warmer it is important to blade the window as soon as possible after it has been mopped to avoid leaving a shadow.
Only wet as many windows as you blade before the water dries.
It is best just to mop one or two windows at a time so that the solution does not have chance to dry.
The two handed technique of mopping and blading simultaneously is good in this situation because the solution is carried away almost immediately.
Use combination tools
When using a tradtional pole combination tools such as the Unger Vice Versa, Ettore Back Flip or Wagtail Flipper will save time switching tools.
Use more water
The most obvious tip is to use more water. Wetting the window more will give you more time to blade it before the solution dries.
If you are using a water fed pole then you should rarely encounter problems unless the windows are really hot. - In which case the answer is to just use more water
Use less soap
Another practical tip would be to use less soap if you use washing up liquid. The solution tends to evapourate quicker if you use too much soap and you will be more likely to leave blade streaks.
Ask your supplier for a slow evapourating product such as Glass Gleam and you will notice the difference.
