Toilet cleaners are chemical solutions used for cleaning the toilet, usually in conjunction with a toilet brush.
Toilet cleaner is sprayed around the rim and the bowl of the toilet prior to the use of the toilet brush. The toilet brush is used to scrub the toilet, removing stubborn stains and biological debris. In recent times, automatic toilet bowl cleaners that clip onto the rim of the toilet and clean with every flush have also become prevalent.
Toilet cleaners tend to be toxic and must be treated with care as they contain disinfectants which can cause skin irritations.
