Create a cleaning checklist. This will ensure that you don't forget anything and that everything gets done in a timely manner. Include tasks such as scrubbing the toilet, cleaning the sink and counter, sweeping and mopping the floor, etc. This will also help if you're teaching someone else how to clean the bathroom - they can simply follow your list! Gather all of your supplies beforehand. This includes things like gloves, scrub brushes, rags, cleaners, etc.
