Both bleach and vinegar can be used to clean a toilet bowl, but they have different properties and uses. Bleach is a powerful disinfectant and can effectively kill germs and bacteria in the toilet bowl. It's especially useful for removing tough stains and grime. However, bleach can be harsh and emit strong fumes that may be harmful if inhaled. It can also damage certain surfaces if not used properly. White vinegar is a natural cleaner and can be used to remove mild stains, watermarks, and mineral deposits in the toilet bowl. It's also an effective deodorizer and can help to eliminate unpleasant odors. Unlike bleach, vinegar is non-toxic and safe for use around children and pets. However, it may not be as effective in killing germs and bacteria as bleach. Ultimately, the choice between bleach and vinegar depends on your personal preferences and the severity of the stains in your toilet bowl. If you have tough stains and want to disinfect the bowl, bleach may be a better option. If you prefer natural cleaners and have mild stains, vinegar may work just as well.
