When you wipe the kitchen side do you have the cloth on the work surface or off ?
Your brush should be clean and any tiny bits left after scrubbing would stay trapped inside the bristles - no need to chase them all over the glass with water
Perhaps your not scrubbing properly Daz 😉

"When you wipe the kitchen side do you have the cloth on the work surface or off ?"- What a daft statement, wiping the kitchen side is not cleaning windows is it.
Here's one for you, when wiping the kitchen side does the cloth stay clean? Of course the bristles are going to get dirty during the course of the day, if there was no dirt whatsoever on the glass then we'd all be out of business.
