Learn how to safely remove soap scum and mineral buildup from your masonry walls. Regular scrubbing and proper rinsing will keep your stone surfaces looking fresh and new.

To clean a brick shower, you need to scrub the masonry with a mild acidic solution and rinse the surfaces thoroughly. This process removes soap scum, mineral deposits, and moisture-related grime without damaging the mortar joints.

Brick is a unique building material because it is porous, durable, and naturally textured. While it adds rustic charm to a bathroom, those same pores easily trap moisture, body oils, and hard water minerals. If left unaddressed, this buildup can lead to discoloration and deterioration of the lime-based mortar holding the structure together. Maintaining a masonry shower requires a balance of effective cleaning and gentle care, as harsh scrubbing tools and overly aggressive chemicals can erode the face of the brick and cause structural issues over time.

Clear out the space

Before introducing any liquids or cleaning agents, remove everything from the enclosure. Take out shampoo bottles, soap dishes, hanging caddies, mats, and any removable seating. Clearing the area gives you unhindered access to every corner, wall, and floor tile, ensuring you do not miss spots hidden behind everyday bathroom items.

Once the enclosure is empty, sweep away loose debris, hair, and dust using a dry broom or a hand brush. Pay close attention to the floor corners and the lower ledges of the walls where dirt tends to accumulate. Follow this dry sweep by rinsing the entire enclosure with warm water from a detachable showerhead or a bucket. This initial rinse washes away surface dust and wets the pores of the brick, which prevents the masonry from greedily absorbing your cleaning solutions too quickly.

Mix a gentle acidic wash

Prepare a cleaning solution using warm water and a mild acid, such as white vinegar or a specialized masonry detergent designed for indoor use. Avoid harsh industrial acids, as they can produce toxic fumes in a confined space and permanently scar the texture of the brick. Combine equal parts warm water and white vinegar in a bucket, or add a few drops of mild dish soap to the mix to help cut through greasy soap scum.

Unlike smooth ceramic tiles that can withstand aggressive scraping, brick requires a chemical approach to lift stains from its microscopic pores.

Scrub the masonry carefully

Take a medium-bristled nylon brush and gently scrub the brick and mortar in circular motions. Avoid using wire brushes or stiff metallic scouring pads, as these tools will scratch, gouge, and permanently ruin the masonry surface. The bristles should be firm enough to dislodge grime from the textured surface, but pliable enough to protect the integrity of the individual bricks.

Pay special attention to grout lines and mortar joints, which are prone to collecting dark mildew spots and soap residue. If you encounter stubborn stains or discoloration in recessed areas, use a smaller soft brush, such as an old kitchen utensil with soft bristles, to work the cleaning solution into thos The Best Power Scrubbers of 2025 | Tested by Bob Vila Our hands-on testing reveals the best power scrubbers for every job.

Rinse thoroughly with clean water

Rinse the entire enclosure from top to bottom with clean, warm water to wash away the loosened dirt and remaining cleaning solution. Use a bucket or a flexible shower hose to flush out every nook, cranny, and horizontal ledge. It is crucial to remove all traces of soap and vinegar, as lingering residue will dry into a dull film and attract fresh dirt almost immediately.

Inspect the walls and floor carefully as you rinse. If you notice patches of lingering soap scum or mineral haze, apply a small amount of the cleaning solution to those specific areas, scrub lightly, and rinse again. Ensure the runoff drains completely and does not pool in the corners of the shower floor.

Dry the enclosure completely

Promote rapid drying by wiping down the brick surfaces with a clean, dry microfiber cloth or a stack of absorbent towels. Press the cloth gently against the walls to absorb excess moisture trapped in the brick texture and mortar joints.

Leave the bathroom door and window open, and run the exhaust fan for an extended period to circulate fresh air through the room. Adequate ventilation helps draw out the remaining moisture from the deep pores of the masonry, ensuring the shower returns to a thoroughly dry state.

Inspect and maintain the surface

Examine the dry brick and mortar for any signs of cracking, crumbling, or excessive wear. Over time, constant exposure to water can cause old mortar to weaken, which may require patching or tuck-pointing to maintain a watertight seal. If the brick appears unusually dry or faded after multiple cleanings, you may need to apply a breathable, specialized masonry sealer designed for wet environments. This protective layer helps repel water and soap scum while still allowing trapped vapor to escape naturally, keeping your brick shower looking well-maintained for the long term.
