Cleaning a toilet cistern typically involves using cleaning agents or automatic cleaners that work with each flush, like our Sweet Lu Automatic Toilet Bowl Cleaner, Blue Bio Enzymatic Automatic Bowl Cleaner and Edco Merri Loo In-Cistern Cleaner. These products help sanitising and maintain the cleanliness of the cistern, prevent stains, and keep the toilet bowl fresh. Regular cistern cleaning also ensures the efficient functioning of the toilet and reduces the need for manual scrubbing.
