How do you check there are no smears after cleaning a window wfp or trad?  Stand at different angles?

[wpclean]

With wfp you don't usually get smears unless some grease has come into contact with the glass.      When you first start cleaning with wfp you tend to over clean the glass, but as you gain more experience you become quicker, and learn the types of frame which need extra particular attention.          We offer a full guarantee with every clean, so if ever there is a problem the custy can always get in touch, and we would be back to clean again.
Obviously the first clean takes a lot longer as you have to really do a deep clean of the frames/windows.
