There was a thread on here a few weeks back where some people were quite vocal about their hate of bleach so I thought I'd try and swap over from bleach.
I lasted three or four weeks but I've gone back to pure thick bleach. Sorry, but toilet duck etc are just not strong enough for my liking (+ the streaky colours dripping down from under the toilet rims even a day or so after use and flushed multiple times were just an eyesore).
