If you are working in a small, enclosed space like a stall shower, turn on the exhaust fan or open a nearby window to keep the air moving.

Mix the Cleaning Solution

You do not need specialized chemical formulas to break down dirt in mortar joints. A simple paste made from everyday household ingredients works remarkably well. In a small plastic bucket or bowl, combine baking soda with enough warm water to form a thick, spreadable paste. The consistency should resemble cake frosting so that it stays put when you apply it to vertical walls or sloped floors.

If you are dealing with particularly stubborn discoloration, you can substitute plain water with white vinegar. When baking soda and vinegar mix, they create a temporary fizzing reaction that helps loosen surface tension on stubborn stains. However, keep in mind that vinegar is acidic. If your tiles are made of natural stone such as marble, travertine, or limestone, avoid acidic liquids entirely, as they can etch and dull the polished surface. For natural stone, stick strictly to baking soda and plain water, or use a mild liquid dish soap instead.

Apply the Paste to the Joints

Once your cleaning mixture is ready, it is time to transfer it onto the mortar joints. You can use a spoon, a small spatula, or even a gloved finger to scoop up the paste and press it directly into the recessed lines.

Work in manageable sections, roughly three feet by three feet at a time. Trying to cover an entire room all at once will cause the paste to dry out before you have a chance to scrub it.

Allow the mixture to sit undisturbed for about ten to fifteen minutes. This dwell time allows the ingredients to penetrate the porous surface of the mortar, softening accumulated grease, soap residue, and ground-in dirt. While you wait, you can prepare your scrubbing tools and gather your rinsing supplies.
