Next, prepare a mild liquid dish soap or general household glass cleaner. You will need this secondary cleanser to remove any oily residue left behind by the lubricant.

Start by clearing the shower stall of all shampoo bottles, soap bars, and hanging caddies so you have unobstructed access to the entire glass surface.

Take a dry microfiber cloth and wipe down the doors to remove any loose dust, hair, or dry surface debris. If large chunks of dirt or grime are left on the glass, they can smear or potentially scratch the surface when you apply the liquid cleaner.

Apply the Lubricating Spray

Hold the can of lubricant approximately six to eight inches away from the glass surface and apply an even, moderate layer across the doors. Focus heavily on the lower halves of the doors, where soap scum and hard water accumulation are typically thickest.

You do not need to drench the entire door in a heavy puddle; a light, consistent sheen is sufficient. As you spray, you will likely notice the liquid immediately beginning to react with the cloudy film, darkening the gray, hazy patches as the petroleum base starts to loosen the bound minerals and oils.

Allow the spray to sit undisturbed on the glass for about five to ten minutes. This waiting period is crucial because it gives the formula time to penetrate deep into the microscopic pores of the glass, lifting away stubborn deposits that ordinary water and wiping alone cannot touch. Do not let the spray dry out completely during this time; if the environment is particularly warm or drafty and you see the liquid evaporating too quickly, apply a light mist more.

Wipe Away Grime and Residue

Take a clean, dry microfiber cloth and begin wiping down the glass in firm, circular motions. You should feel the cloth glide easily as it lifts away the dissolved soap scum, oils, and hard water stains.

For stubborn spots or thick rings of mineral buildup around the handles and bottom tracks, apply a bit of extra pressure with the cloth.

While the glass may look clean after the initial wipe, the petroleum-based spray leaves behind an oily film that will quickly attract new dust and water spots if it is not properly washed off.

Fill a bucket with warm water and a few drops of mild dish soap, or use a standard vinegar-based glass cleaner. Dip a clean sponge or a fresh microfiber cloth into the soapy water and thoroughly wash both sides of the glass doors.

Pay close attention to the edges, corners, and metal framing, as the spray tends to pool in these crevices.

Once the entire surface has been washed with the soapy solution, rinse the glass thoroughly. You can do this by filling a clean bucket with plain warm water and wiping the doors down again, or by using a handheld shower nozzle if your enclosure is equipped with one. Ensure all traces of soap and remaining lubricant are completely rinsed away.

Dry and Polish the Glass

Take a clean rubber squeegee and draw it firmly down the glass from top to bottom, wiping the blade with a dry cloth after each stroke to remove excess water. Squeegeeing immediately after the rinse prevents water spots from forming as the remaining moisture evaporates.

Follow up the squeegee pass by buffing the entire surface with a dry, lint-free microfiber cloth. Move the cloth in circular motions to polish the glass, which helps bring out a clear, streak-free shine.

Step back and inspect the doors from different angles under the bathroom lighting. If you notice any remaining streaks or hazy patches, mist a tiny amount of glass cleaner onto those specific spots and buff them out with a clean cloth.
