Acid cleaners are specialized cleaning products that use acidic compounds to remove tough stains, mineral deposits, and rust. They are commonly used in various settings, including kitchens, bathrooms, and industrial environments. The acids in these cleaners can effectively break down substances like limescale and soap scum, making surfaces cleaner and more hygienic. These cleaners often contain ingredients such as hydrochloric acid, sulfuric acid, or citric acid. While they are effective, it's important to use them with caution, as they can be corrosive and may damage certain surfaces. Always follow the manufacturer's instructions and wear protective gear when using acid cleaners.
