Last updated: October 26, 2026 8:00:00 AM

You can easily remove unsightly mold from your shower caulk using simple household ingredients and a scrub brush. Follow these step-by-step instructions to get your bathroom looking fresh and clean again.

To clean mold off caulk in your shower, mix equal parts white vinegar and water in a spray bottle, soak the affected areas, and scrub the mold away with a stiff brush. If the mold persists, create a thick paste using baking soda and water, apply it directly to the stained caulk, let it sit for a short while, and scrub again before rinsing thoroughly with clean water.

Prepare the Workspace and Protect Yourself

Before you begin tackling the mold in your shower, it is important to prepare both the space and yourself for the task. Mold spores can easily become airborne when disturbed, and the cleaning agents you use will produce strong fumes in a confined area. Start by opening any bathroom windows and turning on the exhaust fan to ensure proper ventilation throughout the cleaning process. If your bathroom lacks a window or fan, consider setting up a portable fan just outside the doorway to pull air out of the space.

Letting it dwell for about twenty to thirty minutes allows the acid in the vinegar to work its way into the roots of the mold embedded within the texture of the caulk. Do not let the area dry out completely during this waiting period; if you notice the vinegar evaporating quickly in a warm bathroom, give the caulk another light spray to keep it moist while the treatment does its work.

Scrub the Mold Away

Return to the shower with a stiff-bristled scrubbing brush, a nylon scouring pad, or an old toothbrush for tighter corners and grout lines. Firmly, but without applying so much pressure that you tear or pull the caulk away from the wall or tub seam, scrub along the length of the caulk line.

If stubborn mold stains remain embedded in the caulk after your initial vinegar treatment and scrubbing, turn to baking soda to provide extra cleaning power and gentle abrasive action. In a small bowl, combine plain baking soda with a small amount of water, stirring continuously until you form a thick, spreadable paste with the consistency of frosting.

Scoop up generous amounts of the paste on your fingers or a sponge and apply a thick layer directly over the remaining mold stains on the caulk. The paste should cling to the surface without instantly sliding off, even on vertical walls. Allow this baking soda mixture to sit on the caulk for fifteen to twenty minutes. The mild alkalinity of the baking soda will neutralize lingering acidic residues from the vinegar and help lift deep-set discoloration out of the caulk without harming the underlying material.
