You can easily remove stubborn soap scum from your glass by mixing common household ingredients into a thick paste. Simply apply the natural mixture to the surface, let it sit for a few minutes, and rinse it away with warm water.

To clean shower doors with baking soda and lemon juice, create a thick paste using these two kitchen staples, apply it to the glass surfaces, and let it sit before scrubbing and rinsing clean. This natural approach effectively tackles soap scum and hard water spots without the need for harsh chemical fumes.

Glass shower doors can quickly lose their clarity. Day after day, hard water from the tap evaporates and leaves behind mineral deposits, while rising steam combines with body oils and soap to form a stubborn residue known as soap scum. Over time, these layers build up into a cloudy haze that obscures the view through the glass. Fortunately, you do not need a cabinet full of specialized chemical cleaners to restore transparency. A simple combination of baking soda and fresh lemons offers an accessible, low-cost way to lift grime through natural abrasive and acidic action.

Gather the Supplies

Before starting the cleaning process, collect the few items necessary for the job. You will need a box of standard baking soda and several fresh lemons, or a bottle of pure lemon juice if fresh fruit is unavailable. Beyond these ingredients, prepare a small mixing bowl, a non-scratch scrubbing sponge or a soft-bristled brush, a clean spray bottle filled with plain tap water, and a few microfiber towels or a squeegee for the final drying stage.

It is also helpful to have a pair of rubber gloves on hand. While the ingredients are natural, the acid in the lemon juice can sting any small cuts on your hands, and prolonged contact with baking soda can dry out your skin. Clear the shower stall of all shampoo bottles, soaps, and hanging caddies so you have unobstructed access to every square inch of the glass doors.

In your small mixing bowl, combine the baking soda and lemon juice to create a workable paste. Start with about one cup of baking soda and slowly squeeze in the juice of two lemons, stirring continuously as you pour. The mixture will instantly begin to fizz and bubble as the alkaline baking soda reacts with the citric acid.

Continue adding lemon juice a little bit at a time until the mixture reaches the consistency of thick frosting or pancake batter. It should be moist enough to spread easily across a vertical surface without immediately sliding down to the floor, yet thick enough to cling to the glass.
