Before you begin the cleaning process, you will need to collect a few basic household items. The primary ingredient is food-grade citric acid, which is typically sold in granular crystal form in the baking or canning aisle of most grocery stores. You will also need a spray bottle, a bowl or bucket for mixing, warm water, a non-scratch sponge or microfiber cloth, and a pair of rubber gloves to protect your hands from the acidic solution.

Having a dry towel on hand is also helpful for the final drying step. Avoid using abrasive scouring pads or steel wool, as these can permanently scratch the glass surface of your shower screen. Clear your workspace by removing any shampoo bottles, soap dishes, or hanging caddies from the immediate area so you have unobstructed access to the glass panels.

Creating the correct liquid mixture ensures the acid can properly cling to vertical glass surfaces without running off too quickly.

Stir or swirl the liquid until all the granules are completely dissolved and the solution is entirely clear. If you are dealing with a heavy accumulation of white crust and cloudy mineral buildup, you can increase the concentration slightly by adding a bit more powder. Once mixed, test the spray nozzle to ensure it produces a fine, even mist rather than a heavy stream, which helps achieve uniform coverage across the screen.

Apply the Liquid to the Glass

Start at the top of the shower screen and work your way down, spraying the liquid generously over the entire glass surface. Make sure to cover areas where water spots and soap scum are thickest, such as the lower half of the screen and the corners near the frame. If your shower screen is particularly neglected and features heavy, stubborn scaling, you can saturate a sponge with the solution and press it against the glass rather than just relying on the spray.

Allow the liquid to run down and coat every square inch, including the metal tracks and hinges if they also suffer from mineral deposits. Take care not to get the solution into your eyes, and consider wearing a mask if you are sensitive to fine mists, although citric acid lacks the pungent, choking fumes associated with conventional chemical cleaners.

Let the Mixture Sit

Patience is the key to this cleaning method, as the acid needs time to chemically break down the calcium and magnesium bonds that hold the mineral crust to the glass. Leave the solution undisturbed on the shower screen for roughly ten to fifteen minutes. Do not let the solution dry completely onto the glass, as this can leave a powdery residue that you will simply have to wash off again.

If you notice the glass drying out in certain spots due to airflow or warmth in the bathroom, give those areas a quick misting to keep the surface damp. During this resting period, the acid works quietly to soften the hard water marks, transforming crusty deposits into a loose, easily removable film.

Scrub Away the Residue

Take your non-scratch sponge or microfiber cloth and begin wiping down the glass in circular motions. You should immediately notice that the cloudy film and rough spots yield easily to the sponge, requiring only moderate pressure rather than heavy muscle. Pay special attention to the edges and corners where grime tends to accumulate over time.
