The spray is the gentlest cleaner for tile grout. You will need to spray the water onto the tile surface and scrub the grout lines with a soft brush. Afterward, it will only be left to tint with a dry cloth. You can also turn to steam cleaners, one of the most effective and environmentally friendly ways to clean. Hot steam flows into the grout lines to loosen all dirt, grime, and grease.

Vinegar and water

If there are slight stains, a mixture of vinegar and water (mixed in equal parts) is perfectly valid. Spray a mild vinegar solution on the grout lines and let it sit for at least 5 minutes. Scrub the grout with a stiff brush and Use warm water to wash the zone

Heating pop and vinegar 

This is quite possibly the most mainstream home cures used to eliminate extreme stains from tile grout. The initial step is to make a glue of preparing soft drink with water and apply it over the grout lines. Then pour equal parts vinegar and warm water mixture over the baking soda paste. There will be a chemical reaction between the baking soda and the vinegar – bubbles will form on the surface, turning into a thick foamy mixture. Once the bubble formation stops, scrub the grout with an old brush to remove build-up. 

Rinse with lukewarm water

Another process to use these two ingredients is by mixing baking soda and vinegar to form a thick paste. Apply this on the grout lines and leave it for 30 minutes to later rinse with water.

Hydrogen Peroxide

If the grout has moderate staining, plash hydrogen peroxide on the grout lines to eliminate earth and stains. Scour with a fiber brush, flush with warm water, and clean. Alternatively, you can make a paste out of hydrogen peroxide and baking soda. Immediately apply it to the tile grout and let it stay for some time. Clean the grout lines with a brush, and as always, we clean the surface with warm water.

Routine Cleaning and Maintenance

For routine cleaning, spray diluted vinegar over the grout at least once a week. Clean with lukewarm water. Periodic maintenance should include the application of sealants to the grout lines. This is an effective way to fill pores and keep grout lines clean. Make sure the grout is completely dry before applying the sealer.
