Brown stains in the toilet bowl are commonly caused by a combination of factors. Hard water, which contains high levels of minerals like iron and calcium, is a frequent culprit, leaving behind rusty or tan deposits. When water evaporates, these minerals can build up and form unsightly stains. Additionally, the presence of tannins from certain medications, tea, or coffee can contribute to discoloration. Mold and mildew growth, especially in humid environments, may also cause brownish stains. Regular cleaning and maintenance can help prevent these stains by removing mineral buildup and ensuring the bowl remains free from mold. Using a toilet cleaner with descaling agents can be particularly effective in addressing and preventing brown stains, keeping your toilet bowl looking fresh and clean.
