Step 1: Mix a paste of baking soda and lemon juice. The consistency of the paste should be about that of pancake mix. Step 2: Spread the paste all along the bottom of the toilet where it meets the floor, the toilet seat, and any other area that gets a lot of over spray. Let it set for about 10-15 minutes. Step 3: When the timer expires spray the dried paste with white vinegar and let it fizzle. Once it is done fizzing wipe it up with a damp cloth. For future reference!
