Toilet cleaner is a household cleaning product designed specifically for cleaning and disinfecting toilets. It typically comes in the form of a liquid, gel, or powder that is applied to the inside of the toilet bowl and left to sit for a period of time before being scrubbed or flushed away. Toilet cleaners are formulated with strong disinfectants such as bleach, hydrogen peroxide, or ammonia, which help to kill germs, bacteria, and viruses that may be present in the toilet bowl. They may also contain ingredients such as surfactants and solvents to help remove stains, dirt, and grime from the toilet bowl.
