Toilet Cleaner:
Pour two cups of baking soda into toilet bowl, scrub the inside, and flush. Now, pour two cups of vinegar into the toilet bowl, swish around the inside, and flush. Do not do this if you have a clog, as you will quickly have a reenactment of Old Faithful in the toilet. However, regular application will keep your drains sparklingly clean.
