This everyday pantry staple provides a mild abrasive action and a high pH level that breaks down fungal growth without relying on harsh commercial fumes.

Preparing the paste in a small container allows you to control the proportions easily rather than trying to mix the ingredients directly on a damp shower wall. Make only as much paste as you anticipate needing for the current cleaning session, as leftover wet baking soda loses its texture over time if left sitting out.

Apply the Paste to the Mold

Put on your rubber gloves to protect your skin from prolonged contact with moisture, mold, and cleaning residue. Use your gloved fingers or a small utensil to scoop up portions of the baking soda paste and smear them directly over the mold patches visible on the shower walls, floor, tile grout, and caulking. Press the paste firmly into the affected areas so that it makes direct contact with the dark spots and fills any microscopic crevices in the grout lines where mold spores take root.

For stubborn mold stains that run along ceiling corners or high up on shower tiles, take care not to let the paste drop into your eyes. If necessary, apply the paste in smaller, controlled dollops. Once every visible patch of mold is thoroughly covered with a thick layer of the white paste, leave the mixture alone to sit undisturbed for a period of time. Allowing the paste to rest gives the mild alkalinity of the baking soda time to break down the organic structure of the mold and loosen its grip on the surface materials.

You may notice the white paste turning grayish-brown as it lifts dirt, soap scum, and mold away from the surface. Pay special attention to corners, the base of the shower stall, and areas where water tends to pool after a shower. Apply moderate pressure; let the texture of the baking soda and the stiffness of the brush do the heavy lifting rather than straining your arm muscles.

Rinse and Inspect the Area

Turn on the shower or fill a bucket with clean, warm water and thoroughly rinse down all the treated surfaces. Use your sponge or microfiber cloth to wipe away any remaining residue of baking soda, making sure to clear out all the loosened debris from the grout lines and corners. Take a close look at the surfaces once they are wet-free and rinsed.

If faint shadows or lingering traces of mold remain in particularly stubborn spots, repeat the process. Apply a fresh layer of the baking soda paste to those specific areas, let it sit briefly, scrub again with the brush, and rinse thoroughly. Repeat applications are often necessary for older mold that has deeply penetrated porous silicone caulking.

Dry and Maintain the Space

Once the shower is completely clean and rinsed, take a dry towel or squeegee and wipe down the walls and glass doors to remove excess moisture. Mold requires humidity and standing water to grow, so establishing a routine of drying the shower after use prevents the problem from returning quickly. Leave the bathroom door open or keep the exhaust fan running for a short period after bathing to pull remaining humidity out of the room. Regular weekly maintenance using a light sprinkle of baking soda and a quick wipe down keeps shower mold under control over the long term.
