To clean mineral buildup off shower walls, you need to dissolve the hard water deposits using an acidic solution and then wipe away the residue with a non-abrasive pad. This simple process breaks down the crusty, white, or chalky layers left behind by evaporating tap water without damaging the surface of your shower.

Clear the Shower and Protect Surrounding Areas

Before you begin working on the walls, empty the shower completely. Remove all shampoo bottles, soap dishes, razors, loofahs, and hanging caddies. Clearing the space ensures you have a completely unobstructed area to work in, allowing you to reach every corner and edge without knocking things over or missing spots.

Start at the bottom of the shower walls and work your way up to the top. Spray the liquid generously over all the areas showing mineral crust, making sure to coat the cloudy, white buildup thoroughly. Working from the bottom up is important because it prevents cleaner from running down dry walls and leaving streaks that can obscure your view of where you have already sprayed.

For vertical walls where the liquid tends to slide off too quickly before it can work, you can create a clinging layer by soaking paper towels in the liquid and pressing them flat against the stubborn spots on the tile. The paper towels act as a poultice, holding the moisture and the acid directly against the mineral deposits for an extended period.

Patience is the most important element of this task. Once the walls are thoroughly coated, leave the shower alone and allow the liquid to sit undisturbed.

Depending on how thick and old the buildup is, this process can take anywhere from fifteen minutes to an hour. During this time, you may notice a slight bubbling or fizzing sound as the acid reacts with the minerals.
