We bought a new toilet a few months ago and find that the flush leaves several areas untouched requiring the need of a brush (You'll get what I am talking about).
We have a round brush which does not get into the corners and an old and fairly well used one which is straight and gets in the corners. It's a bit manky and the brush and the holder do not match.
So, I thought I would buy a new one. Trouble is, you can't see from the outside whether it is a round brush or a flat one either in reality or on the internet. All you see is the holder. Any ideas how to get round that?
