CLEANING WINDOWS WITHOUT SILLS IS LIKE WASHING YOUR CAR BUT NOT THE WHEELS.

Wheels? but I thought wheels were extra

Seriously though I don't clean cills as a general rule but if asked am only too happy to oblige.

Must have missed the "must clean cills" page in the things you have to do if you want other window cleaners  to think you are a super window cleaner book. 

Mostly I am concerned with what my customers think not what other window cleaners think.
