Hello, I have used Domex Toilet Cleaner and this is my own view which has been formed after using it.
Toilet cleaner should always be a good disinfectant and deodourizer. Domex Toilet Cleaner is really poor when it comes to deodourizing the foul smell. The cleaner is also impotent to bring a shine after cleaning which is the least expected thing that it should be able to do as a toilet cleaner.
I was particularly unhappy with the smell it leaves behind which is not at all acceptable. So rather than deodourizing, it casts its own pathetic odour to an annoying extent. There are better toilet cleaning products available in thce market than it.
