If your shower screen turns cloudy a few days after you've cleaned it, you're not doing anything wrong. A foggy screen almost always comes down to three things: soap scum, hard water marks, and mould. Each one looks much the same through the steam, but each clears in a slightly different way, and none of them needs a scrubbing brush or anything that could scratch the glass.
This guide starts with a quick daily habit that keeps a clean screen clear, then works through a problem-by-problem deep clean for when build-up has already set in.
The Two-Minute Habit That Keeps Glass Clear
The simplest way to keep a shower screen looking clean is to stop build-up settling in the first place. It takes about two minutes a day, and you’ve likely already seen this recommendation across the web.
While the glass is still warm and wet, run a rubber squeegee down it or wipe it with a microfibre cloth. That clears most of the water before it dries and leaves marks behind. A few times a week, follow up with a light spray of shower cleaner and a quick wipe. And whenever you can, open a window or run the exhaust fan for a while after a shower, which keeps the whole recess drier and slows mould.
Stay on top of those three small steps and the deep clean below becomes an occasional reset rather than a weekly chore. It's also the surest way to keep glass streak-free, since most streaks come from water drying on its own.
Before You Deep Clean: The Gentle-Tools Rule
A quick word on what to use before we get into each problem. Soft tools do the work here, so build-up lifts away without marking the glass.
Keep a few things within reach:
-
A rubber squeegee
-
A non-abrasive shower spray or gel
-
An old toothbrush for seals and grout lines
It's worth keeping scourers, abrasive pads and melamine "magic" erasers away from shower glass. They can leave fine scratches in the surface coating, and those scratches then hold onto more grime, so the glass clouds over faster next time. A soft cloth and a little dwell time will shift the same build-up without the risk.
Shifting Soap Scum
Soap scum is the chalky, slightly waxy film that builds up where soap meets the minerals in your water. It settles in thin layers, which is why the glass looks cloudy and dull rather than obviously dirty, and why wiping with water alone rarely touches it.
The trick is to soften the film first, then wipe rather than scrub.
Warm the glass with a quick rinse so the cleaner spreads and works faster. Apply your cleaner across the whole screen, then give it time to break the film down before you touch it. Wipe it away with a damp microfibre cloth, working top to bottom, then rinse and squeegee the glass dry for a clear finish.
Try It Yourself
Warm the glass, apply your cleaner, and let it sit for a minute or two while you wipe down the rest of the recess. Come back, wipe the screen with damp microfibre, then rinse and squeegee. Letting it dwell does the work that scrubbing would, with none of the risk to the glass.
Reach for: Shower Power Citrus
Spray it across the screen, leave it 30 to 60 seconds to break down the scum, then rinse and wipe dry for a streak-free, citrus-fresh finish. It's fume-free and septic-safe, so it suits low-ventilation bathrooms and homes with kids and pets. For glass that has years of build-up clinging to it, Shower Power Gel holds onto vertical surfaces for longer, which gives it more time to work.
Clearing Hard Water Marks
Hard water marks are the cloudy spots and faint streaks left behind when water dries on the glass and the minerals in it stay put. Much of Australia has fairly hard water, so this one is common, and it often gets mistaken for soap scum. The difference is that hard water marks feel more like a thin mineral film or spotting, and they build up fastest on the parts of the screen that catch the spray.
Dwell time matters more than effort here too. A cleaner that handles limescale and calcium needs a minute to soften the deposits, after which they wipe away easily. Finish with a dry buff using clean microfibre, which lifts the last of the film and leaves the glass clear rather than streaky.
Try It Yourself
Apply your cleaner, let it sit, then wipe and rinse. For stubborn spots, repeat the step rather than pressing harder. A final buff with a dry cloth is what gives you that streak-free finish.

It's formulated to cut through hard water stains, limescale and calcium deposits as well as soap scum, so the same bottle covers most of what clouds a screen. Spray, leave it to work, rinse and wipe dry.
Tackling Mould In Seals And Grout
Mould in the shower tends to show up as dark spotting along the silicone seals and in the grout lines rather than on the glass itself. It takes hold where things stay warm and damp with little airflow, which is exactly what a shower recess offers.
The long-term fix is airflow. Running the fan or opening a window after each shower, and giving the seals a quick wipe so they dry out, makes the biggest difference over time. For mould that has already set in, apply a mould treatment directly to the affected silicone or grout, let it do its work, then wipe the area clean. An old toothbrush helps you reach into the corners of the seals.

Keep the recess dry and well-aired day to day, and treat any spotting as soon as you notice it, while it's still on the surface and easy to clear.
Reach for: Mould Power
A mould killer made for bathroom silicone, grout and tiles. Apply it to the affected area, allow it to work, then wipe clean. It also handles mould on fabric and around the home, so it earns its place in the cupboard.
Shower Screen Cleaning Hacks
A few small habits make a clean screen far easier to keep:
-
Squeegee while the glass is warm. Water clears more easily before it cools and dries, so a quick pass straight after your shower saves a deep clean later.
-
Choose microfibre over paper towel. Microfibre lifts the film and buffs the glass clear, while paper towel tends to smear and leave lint.
-
Warm the glass before you clean. A quick rinse with warm water helps any cleaner spread and work faster.
-
The hotel trick is little and often. Hotels keep their screens clear by wiping them down after every clean and finishing with a quick dry, not by scrubbing once a week. The habit is doing the work, not the elbow grease.
-
For years of soap scum, give it time. Let the cleaner dwell longer and repeat the step rather than reaching for something abrasive. The build-up softens in layers.
-
Air it out for mould. Most shower mould is a ventilation problem first. A fan or an open window after each shower does more than any single clean.
-
Use one product at a time. Cleaning products work best on their own, so finish with one before moving to another.
Keeping Your Screen Clear
Once the glass is clear, the daily habit is what keeps it that way. A quick squeegee after each shower, a light spray a few times a week, and good airflow will hold off soap scum, hard water marks and mould between deep cleans. A clear screen takes far less work to maintain than a cloudy one takes to rescue, so the few minutes a day pay off quickly.

Common Questions
What's the best thing to clean a shower screen with?
A non-abrasive shower cleaner and a microfibre cloth handle most build-up on glass. Spray the cleaner, let it dwell so it softens the film, then wipe and squeegee dry. Soft tools matter more than strong scrubbing, which can scratch the glass.
How do I remove years of soap scum from glass?
Soften it in layers rather than scrubbing it off. Apply your cleaner, let it sit for a few minutes, wipe with damp microfibre, then repeat if needed. A clinging gel cleaner helps on vertical glass because it stays in contact longer.
Will vinegar or bicarb scratch my shower screen?
Vinegar and bicarb are liquids and powders rather than abrasives, so the bigger risk to glass comes from scourers, abrasive pads and melamine erasers, which can leave fine scratches. Whatever cleaner you use, apply it with a soft cloth.
How do I get rid of black mould in the shower silicone?
Apply a mould treatment made for bathroom silicone and grout directly to the affected seals, let it work, then wipe clean, using an old toothbrush to reach the corners. Keeping the seals dry and the recess well-aired helps stop it returning.
How do I keep my shower screen streak-free?
Squeegee or wipe the glass dry while it's still warm and wet, before the water can dry on its own. Most streaks come from water and minerals drying in place, so clearing them early is what keeps the glass clear.
What do hotels use to clean glass shower doors?
Hotels rely on routine more than any single product. Housekeeping wipes the glass down after each clean and dries it off, so build-up never gets the chance to set. The same little-and-often habit works just as well at home.
