After you’ve mixed together the above ingredients, you can then place the solution in a squirt bottle with a small nozzle, such as the Restaurantware 8 Ounce Squeeze Bottle on Amazon. Because the tip of these bottles is so small, it should fit perfectly into your grout grooves, which will make applying the cleaner extra simple. Just place the nozzle in the grout and drag it across the tiled surface. Once it’s applied, allow the cleaner to sit for 15 minutes before wiping it off with a damp cloth.
Then, to clean the grout, lightly scrub with a bristle brush and hot water, which you can keep in a bucket beside you. The stains and dirt should come up with just a few swipes of the brush. As you continue, keep dipping the brush back into the water. If you’re cleaning grout on a wall, finish the job by washing the tile with a damp cloth. On the other hand, if you’re cleaning grout on the floor, vacuum up any extra pieces of baking soda and mop the entire surface.
