Why do some windows spot & others sheet?
« on: June 29, 2006, 08:36:01 am »
I have noticed that some windows sheet & some stay wet in droplets for hours with wfp! Why is this???

The ones that sheet are great :) They dry in seconds and usually come up spot free.

My house is fitted with the same windows all round & only 2 of them sheet and rest stay wet with droplets for hours.

Why is this?

If all windows sheet this would make the life of the wfper so easy ;)

Because there are 2 types of glass , cant remember exactly , ..........phobic is 1 of them !
I wouldnt worry about it , they should come up ok anyway , i always give the droplet type a little longer rinse .

In some cases its because of what they have been cleaned with in the past.
Ever seen windows that have been cleaned with Mr Muscle or similar?
Some/most washing up liquids contain some form of surface brightener to make the dishes gleam. This makes them look cleaner.
That stays on the glass and causes beading. After a few cleans it goes. Another reason why first cleans are the worst.
