Step By Step Instructions For How To Remove Urine Stains From Grout
#1. Soak Up The Excess Urine
Assuming you are cleaning a fresh stain, use the paper towels to soak up any excess urine that may be on the floor or wall where you will be cleaning the grout.
After you have soaked up all of the visible urine, use a clean, damp paper towel or cloth to scrub the area and remove any urine residue that may still be on the surface of the grout or tiles.
#2. Apply The Enzyme Cleaner
Pour or spray enough enzyme cleaner to soak the stained area and let it sit per the instructions on the bottle.
For some cleaners, it may need to sit longer than others.
After the instructed amount of time, scrub the area and ensure all of the enzyme cleaner has been removed.
If any stain or odor remains, repeat this step as many times as necessary to get all of the urine out of the grout.
#3. Mix The Baking Soda Solution
In a large bowl or another container, mix 7 cups of water, 1/2 cup of baking soda, 1/3 cup ammonia, and 1/4 cup vinegar.
Mix the solution well and apply it directly to the urine stain.
Leave the solution to sit for up to an hour.
For smaller stains, you can leave it for up to 30 minutes.
After 30-60 minutes, scrub the area with a toothbrush until you are sure you have removed all of the urine.
The enzyme cleaner should have done most of the work, but the solution you mixed will help eliminate the odor more than just enzyme cleaner alone.
Leave the area to dry and enjoy your freshly cleaned grout.
