Just a little tip,i have found today.When cleaning your windows outside,use a little alcohol,i had half a bottle of red before and i did not give a hoot how streaky they were.

Alas, that would work for me, but I would have to persuade my wife to drink some too which is not so easy. Fortunately we have a cheap and efficient window cleaner so she can criticize him for anything that gets missed, instead of me!
