Limescale buildup in the bathroom – why it happens and how to remove it

Limescale deposits occur, for example, in the bathroom when water with high levels of calcium and magnesium ions evaporates. Limescale deposits are particularly common where water often splashes or runs, such as on shower walls, sinks, and toilets.

When the water evaporates, calcium and magnesium ions bind together, creating a hard, white coating that is difficult to remove. Over time, these deposits can thicken and affect the functionality of shower heads or clog pipes. Limescale can also make the bathroom look dirty even when it is clean, making regular cleaning important to keep limescale under control.

An acidic cleaning agent (low pH) creates a reaction where calcium carbonate reacts with the acid. This forms carbon dioxide (CO₂), water (H₂O), and a soluble calcium salt, meaning the limescale no longer has a solid form.

The reaction may take time, which is why we have created a limescale remover in gel form that can adhere to vertical surfaces, such as a shower wall, and work to dissolve the limescale.




How to use:

1. Apply the gel to the limescale surface. Use a scouring sponge or cloth for application.

2. For heavy limescale, let the gel work for 15–20 minutes and then scrub clean with an eco-fiber cloth, brush, or scouring sponge. For lighter deposits, apply the gel and scrub off immediately.

3. Gently scrub with a sponge or eco-fiber cloth to remove dissolved limescale. Rinse and dry the surface thoroughly.

      Note: The gel has a low pH and should not be used on marble or limestone materials.

      Västerbottenssåpa's limescale remover contains no corrosive or toxic substances. Thanks to the gel texture, it can adhere to vertical surfaces, such as shower walls, and effectively dissolve limescale. The product contains no harsh chemicals such as phosphoric acid, hydrochloric acid, formic acid, or limonene.

      Questions and Answers

      1. Why do limescale deposits form on surfaces in the bathroom?

      Limescale deposits occur when water containing calcium and magnesium ions evaporates and leaves a hard, white coating on surfaces frequently exposed to water, such as shower walls and sinks.

      2. How does an acidic cleaning agent work against limescale?

      An acidic cleaning agent reacts with calcium carbonate and dissolves the limescale by forming carbon dioxide, water, and a soluble calcium salt. This process can take time, making a gel effective for keeping the cleaning agent in place and letting it work longer.

      3. What method is recommended for cleaning heavy limescale deposits?For thicker limescale deposits, the gel can be applied and left to work for 15–20 minutes before the surface is scrubbed clean with an eco-fiber cloth, brush, or scouring sponge.
