Please choose the correct ending to complete the given sentence: Home and Garden: [header] How to clean a toilet with coke [title] Use lots of scrubbing. [step] A good old-fashioned toilet brush is your best bet if simple flushing won't remove your stains. The mechanical action of a brush (or a similar item, like an abrasive pad) will further loosen built-up stains and help remove them from the walls of the bowl after you've treated them with coke.

Ending1: Scrub the inside of the toilet bowl for at least 5 to 10 minutes. Do not scrub the inner walls of the bowl; remember, this is where stains are most likely to hide. Ending2: Be sure to wash your hands after scrubbing and wear gloves if germs make you squeamish. [substeps] For best results, scrub before and after using the coke. Ending3: Just make sure your brush is large enough to have a sharp tip. [substeps] Never use something that is too long or too thin. Ending4: Wash your hands with soap and water before and during your clean-up. Scrub the sides and inside of the toilet bowl with a regular bristled brush, except for the chamber.
