A beautiful glass shower screen can make even a small bathroom feel brighter, cleaner and more spacious. But keeping it that way isn't always easy.

If you've noticed cloudy patches, chalky white marks or streaks appearing on your shower enclosure, you're probably dealing with limescale and hard water deposits.

It's a particularly common problem in UK homes with hard water, where dissolved minerals are left behind as water droplets dry on the glass.

Over time, those deposits build up, making even a freshly cleaned bathroom look dull.

The good news? You don't need to spend hours scrubbing your shower screen.

With the right cleaner and a few simple habits, you can remove stubborn limescale, restore clarity and help keep your glass looking cleaner for longer.

Here's everything you need to know.

Why Does Shower Glass Become Cloudy?

If your shower screen looks misty, cloudy or covered in white spots, hard water is often responsible.

Hard water contains dissolved minerals, particularly calcium and magnesium. When shower water evaporates, mineral deposits remain on the glass.

As more water dries, those deposits accumulate, creating the familiar white, chalky appearance known as limescale.

Several common bathroom problems can contribute to cloudy shower screens:

• Hard water: Leaves mineral deposits behind as droplets evaporate.

• Soap residue: Soap and body wash can combine with minerals to create a cloudy film.

• Shampoo and conditioner: Products can leave a residue on glass and shower fittings.

• Infrequent cleaning: Mineral deposits become harder to remove when left untreated.

• Poor ventilation: Water takes longer to evaporate, leaving shower surfaces wet for extended periods.

Limescale is especially noticeable on clear glass, dark bathroom fittings and shower doors exposed to repeated splashes.

If left for a long time, mineral deposits can become increasingly difficult to shift, and severe untreated build-up may eventually contribute to permanent surface marking.

Regular cleaning is much easier than tackling months of accumulated limescale.

What Is the Best Way to Remove Limescale from Shower Glass?

The best approach depends on how heavily the glass is affected.

Light water spots may wipe away with a damp cloth, but stubborn mineral deposits usually need a specialist descaler.

Unlike an ordinary glass cleaner, which is primarily designed to remove fingerprints and everyday dirt, a shower glass descaler is formulated to tackle the mineral deposits responsible for cloudy glass.

GLEAN Shower Glass Cleaner & Descaler 500ml is designed for this exact problem.

Its fast-acting formula helps remove limescale, mineral deposits and hard water staining from glass and suitable plastic shower screens.

It also leaves a protective water-pearling effect, helping water bead on the surface and reducing the opportunity for new deposits to accumulate.

For showers that are regularly exposed to hard water, that combination of cleaning and surface protection can be particularly useful.

What You'll Need

Before you begin, gather a few cleaning essentials:

• GLEAN Shower Glass Cleaner & Descaler 500ml

• A clean, soft microfibre cloth

• A non-abrasive sponge

• Warm water

• A shower squeegee

• Rubber gloves

• A dry cloth for polishing

Important: Read the product label before use. Avoid abrasive pads, wire wool and sharp tools, which can scratch shower glass or damage protective coatings. Check the manufacturer's instructions if your shower screen has a specialist surface treatment.

How to Remove Limescale from Shower Glass: Step by Step

Follow these simple steps to clean cloudy shower glass and restore its clarity.

1. Rinse the Shower Screen

Start by rinsing your shower screen with warm water to remove loose dirt, shampoo residue and surface grime.

If there is a heavy layer of soap residue, gently clean it first with a suitable mild cleaner, then rinse thoroughly.

This allows the descaler to work more directly on the mineral deposits rather than sitting on top of everyday dirt.

Make sure any previously used cleaning product has been completely rinsed away.

2. Apply GLEAN Shower Glass Cleaner & Descaler

Spray GLEAN Shower Glass Cleaner & Descaler evenly over the affected glass.

Focus on areas where limescale is most visible, such as:

• The lower section of the shower screen

• Areas around door handles

• Glass near shower heads and taps

• Shower door edges

• Sections where water regularly collects or dries

Work in manageable sections so the cleaner doesn't dry before you have time to rinse it.

Protect surrounding sensitive surfaces and avoid unnecessary contact with metal trims and decorative finishes.

3. Leave for 2–5 Minutes

Allow the cleaner to work for approximately 2–5 minutes, following the product instructions.

This contact time gives the descaling formula time to work on the mineral deposits responsible for white marks and cloudy glass.

Do not allow the product to dry on the surface.

For stubborn limescale, a second treatment may be needed rather than extending the contact time beyond the recommended period.

4. Wipe Gently

Using a soft sponge or microfibre cloth, gently wipe the treated surface.

There should be no need for aggressive scrubbing.

Avoid abrasive cleaning powders and rough scouring pads, which can damage glass coatings and scratch surrounding fittings.

Pay particular attention to the lower corners of the screen, where mineral deposits often build up.

5. Rinse Thoroughly

Rinse the treated glass with plenty of clean water to remove loosened limescale and any remaining cleaning product.

Make sure any cleaner that has contacted nearby shower fittings is also rinsed away thoroughly.

6. Dry and Polish

Use a clean, dry microfibre cloth or shower squeegee to remove excess water.

Buff the glass gently to achieve a clear finish.

Drying the glass prevents fresh water droplets from evaporating and leaving another layer of mineral deposits.

The result should be a cleaner, clearer shower screen with fewer visible water marks.

How to Remove Stubborn Hard Water Stains from Shower Screens

Some shower screens develop a thick layer of mineral deposits, particularly if they haven't been descaled for several months.

These deposits often appear as:

• Chalky white spots

• Cloudy patches that won't disappear when wiped

• Rough, crusty marks along the bottom edge

• White deposits around glass door fittings

• Persistent marks around the shower head

If your shower glass is heavily affected, start with the normal cleaning method.

Apply a specialist descaler, allow the recommended contact time and rinse thoroughly.

If deposits remain, repeat the process as directed.

Avoid trying to scrape away stubborn marks with metal blades or abrasive tools.

What if the glass is still cloudy after cleaning?

Not every cloudy patch is removable limescale.

Long-term mineral deposits, damaged surface coatings and glass etching can sometimes create marks that ordinary cleaning won't remove.

If repeated suitable cleaning makes no difference, the surface may be permanently affected rather than simply dirty.

Shower Glass Cleaner vs Vinegar: Which Works Better?

White vinegar is often recommended as a household solution for removing limescale.

It can help dissolve light mineral deposits on some uncoated glass surfaces, but it isn't suitable for every bathroom material.

Vinegar can damage certain natural stones, finishes and protective coatings. It can also leave an unpleasant smell and may not provide the same finish as a specialist shower glass cleaner.

Here's how common cleaning methods compare.

For regular bathroom maintenance, a specialist shower glass descaler offers a straightforward way to target mineral build-up without relying on abrasive scrubbing.

Safety: Never mix vinegar, descaler or other cleaning products with bleach. Combining incompatible products can release dangerous gases. Always rinse away one cleaner completely before using another.

Can You Use GLEAN on Plastic Shower Screens?

Yes. GLEAN Shower Glass Cleaner & Descaler is designed for both glass and suitable plastic shower screens.

Plastic shower enclosures can develop the same cloudy mineral deposits as glass, particularly in hard-water areas.

However, plastic surfaces can be more vulnerable to scratching, so it's important to use a soft cloth or non-abrasive sponge.

Always check for specialist coatings and test a small, inconspicuous area first.

Avoid prolonged contact with non-colourfast, sealed or otherwise sensitive surfaces.

Can You Remove Limescale from Shower Heads and Taps?

Limescale doesn't just collect on shower screens.

It can also build up around taps, shower heads and fittings, leaving white mineral deposits and making polished surfaces look dull.

GLEAN Shower Glass Cleaner & Descaler is also intended for suitable taps and shower heads.

For these areas:

1. Check that the fitting's finish is compatible with a descaler.

2. Apply the cleaner carefully, avoiding overspray onto surrounding sensitive materials.

3. Leave for the recommended 2–5 minutes without allowing it to dry.

4. Wipe gently using a soft cloth.

5. Rinse thoroughly and dry.

Take extra care with aluminium, plated finishes and decorative coatings. The product guidance advises avoiding prolonged contact with aluminium and rinsing immediately if contact occurs.

For heavily scaled shower heads with blocked spray nozzles, follow the manufacturer's descaling recommendations.

How to Keep Shower Glass Clear for Longer

Once you've removed the limescale, the next step is preventing it from building up again.

A few small changes to your cleaning routine can make a noticeable difference.

Use a Shower Squeegee After Every Shower

One of the easiest ways to reduce water marks is to remove water before it dries.

Keep a shower squeegee nearby and run it across the glass after each use.

It only takes a few seconds and removes much of the water that would otherwise leave mineral deposits behind.

Dry the Edges and Fittings

The lower edge of shower screens and the areas around handles and hinges often collect water.

A quick wipe with a microfibre cloth helps prevent water from sitting in these places.

Clean Regularly

Don't wait until the glass becomes completely cloudy before cleaning it.

Check your shower screen every week and remove new mineral deposits before they become difficult to shift.

In hard-water areas, more frequent cleaning may be necessary.

Improve Bathroom Ventilation

Run your extractor fan during and after showering to help reduce humidity.

Where practical, allow fresh air to circulate once the bathroom is no longer in use.

Ventilation helps surfaces dry more quickly, although removing water droplets directly remains the most effective way to limit water spotting.

Choose a Cleaner with a Water-Repelling Finish

Some specialist shower cleaners offer more than simple dirt removal.

GLEAN Shower Glass Cleaner & Descaler is formulated to leave a water-pearling effect, encouraging droplets to bead on the treated surface.

This can help reduce the build-up of new deposits and make ongoing cleaning easier.

It doesn't eliminate the need for maintenance, but it provides a useful addition to a regular cleaning routine.

How Often Should You Clean Shower Glass?

The frequency depends on how often you use your shower and the hardness of your water.

Homes in hard-water areas may need more frequent descaling.

If your shower is used several times a day, removing water after each use will make a particularly noticeable difference.

Why Choose GLEAN Shower Glass Cleaner & Descaler?

Not all bathroom cleaning sprays are designed to tackle stubborn mineral deposits.

Ordinary glass cleaners are useful for removing fingerprints and everyday marks, but heavier limescale needs a more targeted approach.

Other Bathroom Cleaning Problems to Watch For

Limescale isn't the only cause of a bathroom looking tired.

Shower screens, grout and silicone seals can all develop different types of staining, and each needs the right approach.

Black mould around shower seals

Dark spotting on grout and silicone is usually a mould problem rather than limescale.

If you're dealing with black marks around the shower, read our guide to the Best Bathroom Mould Remover.

Mould on walls and ceilings

Persistent black staining on painted bathroom walls can indicate condensation, poor ventilation or an underlying damp issue.

Find out more in our guide to How to Remove Black Mould from Bathroom Walls.

Tired or damaged silicone sealant

If shower sealant has become cracked, loose or badly discoloured, cleaning alone may not restore it.

Damaged seals often need to be removed and replaced to maintain a watertight finish.

Using the correct cleaner for each problem helps protect bathroom surfaces while keeping the whole space looking fresh.

Frequently Asked Questions

What is the best way to remove limescale from shower glass?

The best approach is to use a specialist shower glass descaler designed to remove mineral deposits and hard water stains. Spray GLEAN Shower Glass Cleaner & Descaler onto a compatible surface, leave for 2–5 minutes without allowing it to dry, then gently wipe and rinse thoroughly. Finish with a dry microfibre cloth for a clearer result.

Why does my shower glass look cloudy even after cleaning?

Cloudiness is often caused by mineral deposits from hard water, which ordinary glass cleaners may not dissolve. Soap residue can also contribute to a hazy appearance. If suitable descaling doesn't improve the glass, permanent etching or damage to a surface coating may be responsible.

Can I use GLEAN Shower Glass Cleaner on plastic shower doors?

Yes. GLEAN is formulated for glass and suitable plastic shower screens. Use a soft, non-abrasive cloth and check the manufacturer's recommendations, particularly if the surface has a protective coating.

How long should I leave shower glass descaler on?

GLEAN Shower Glass Cleaner & Descaler has a recommended contact time of approximately 2–5 minutes. Do not allow it to dry on the surface. Always follow the label directions rather than leaving the product on for longer.

Can I remove limescale without scrubbing?

A specialist descaler helps loosen mineral deposits so they can be removed with gentle wiping. Heavy build-up may require a repeat treatment, but abrasive scrubbing should be avoided because it can damage the glass or protective finish.

Does GLEAN Shower Glass Cleaner leave streaks?

GLEAN is designed to leave a clear, streak-free finish. For best results, rinse thoroughly after treatment and dry with a clean microfibre cloth. Using a dirty cloth or allowing cleaning residue to dry can cause unwanted marks.

Can I use GLEAN Shower Glass Cleaner on chrome taps?

The product is intended for suitable taps and shower fittings, but compatibility depends on the material and finish. Test an inconspicuous area, avoid prolonged contact and rinse thoroughly. Take particular care with aluminium, plated and decorative finishes.

How do I stop limescale coming back on my shower screen?

Use a squeegee after every shower to remove water before it dries. Wipe the lower glass edges, clean regularly and use a suitable descaler when mineral deposits begin to appear. GLEAN's water-pearling finish can also help reduce future build-up, although regular maintenance is still important.

Is white vinegar safe for shower glass?

White vinegar can remove light limescale from some uncoated glass surfaces, but it isn't suitable for every shower enclosure. It may damage natural stone, protective coatings and certain metal finishes. Check surface compatibility before use and never mix vinegar with bleach or other cleaning products.

Can limescale permanently damage shower glass?

Yes. Severe, long-standing mineral build-up can contribute to surface marking or etching. If cloudy patches remain after suitable cleaning and descaling, the marks may be permanent. Regular cleaning helps prevent deposits from reaching this stage.

Keep Your Shower Glass Crystal Clear with GLEAN

Cloudy shower screens and stubborn water marks are frustrating, but they don't need to become a permanent feature of your bathroom.

Regular cleaning, a quick squeegee after showering and the right descaling product can make a big difference.

With its powerful limescale-removing formula, convenient spray application and protective water-pearling finish, GLEAN Shower Glass Cleaner & Descaler helps restore clarity and makes looking after your shower screen easier.
