Since urine is constantly in contact with a toilet, an odor can be present if the toilet is not cleaned properly and regularly. To keep the toilet clean and remove the urine smell, use a cleaning solution to break up the enzymes in the urine, disinfect the area and also to deodorize. There are several chemically based commercial products that will help you complete this task, but a simple homemade solution costs just a few cents and is just as effective in removing urine smell from a toilet.
Sprinkle 2 cups white vinegar and 1 cup baking soda into the toilet bowl.
Fill a spray bottle with white vinegar. Spray the upper half of the toilet bowl. Let the solution sit overnight.
Spray a fresh mist of the vinegar in the toilet bowl the next morning, and scrub with a toilet-bowl brush. The baking soda and vinegar combination deodorize and disinfect the toilet bowl.
Flush the toilet. Clean the toilet bowl with this solution once a week to prevent the urine odor from returning.
