How to Clean Pet Stains off Tile Grout
Tile grout can be discolored by pet urine and excrement. Since urine can sometimes be acidic, it eats on the sealant and penetrates the grout causing nasty discoloration. To remove the stains, here are some recommended solutions.
Step 1 - Start with Mild Cleaners
If the stains in the tile grout are mild, use mild cleaners such as baking soda and mild detergent. To create a baking soda cleaning solution, simply add water to the powder, mix it in a container, and apply it on the stained grout. For the detergent, mix it well with water in a container. Apply the baking soda or the detergent mix onto the tile grout and allow it to sit for about ten minutes. Afterwards, brush the grout to dislodge the stains. Rinse well with water afterwards.
Step 2 - Use Vinegar Solution
Vinegar will not only remove the stains; it also removes the odor. To use vinegar as a cleaning solution, prepare a mixture of equal parts of warm water and vinegar in a container. Spread the solution in between the tiles and leave it be for 10 minutes. Scrub the grout with a brush and rinse thoroughly with water.
Step 3 - Use Bleach
If the stain is hard to remove, use bleach instead. Bleach can be in the form of chlorine, hydrogen peroxide, or oxygen bleach powder. For safety reasons, use oxygen bleach as a cleaning solution. Dilute the powder in water and apply it liberally on the tile grout. Let it sit for about ten minutes. Notice that the bleach will cause some bubbles to appear. Although it may seem that the bleach is eating through the grout, do not worry because it is only dissolving the stains and dislodging them for easier cleaning. Afterwards, scrub the grout in between the tiles and rinse well with water.
Step 4 - Replace the Grout
If the grout is pretty worn out, heavily discolored, or damaged, then the best solution is to replace it entirely with new grout. This should be done especially if the grout is too old and damaged. This procedure will also enhance the look of the tiles and provide structural repair.
Prepare the needed materials for the re-grouting process. Remove the top layer of the grout using a grout saw. Afterwards, clean the dust and debris using a vacuum cleaner. Wipe off any remaining dust and dirt.
Mix the grout in a container making sure to follow the recommended amount of water and grout. Apply the grout in between the tiles using a rubber float. Work the grout into the joints in a firm one-directional stroke. Allow the grout to set for about twenty minutes and wipe the residue with a clean paper towel. Allow the grout to dry for about 24 hours before applying grout sealer.
