Toilet cleaners are specialized cleaning products designed to remove stains, odors, and bacteria from toilets. They often come in liquid, gel, or tablet forms and contain ingredients that help break down tough deposits like limescale and mineral buildup. Many toilet cleaners also have disinfecting properties to kill germs and ensure a hygienic bathroom environment. These products are typically applied directly to the toilet bowl and left to sit for a specified time before scrubbing with a toilet brush. Common ingredients in toilet cleaners include bleach, hydrochloric acid, and citric acid, which work together to clean and sanitize effectively.
