Can You Use Viakal On Shower Screens?
Quick Answer
If you’ve got cloudy watermarks or stubborn white limescale building up on your shower screen, it’s normal to reach for a dedicated limescale remover like Viakal. The short answer is yes, Viakal can be used on many shower screens, but only when the glass and surrounding materials are compatible and you use it correctly.
Below is a practical guide to help you clean safely, avoid damage, and keep your shower glass looking clear.

Why Shower Screens Get Cloudy Build-Up
Most “cloudy” shower glass is caused by a mix of:
Limescale (mineral deposits from hard water)
Soap scum (soap plus body oils plus minerals)
Cleaner residue that wasn’t rinsed away properly
Viakal works by breaking down limescale, which is why it’s often effective when general bathroom sprays aren’t.
How To Use Viakal On A Shower Screen (The Safe Way)
| Step | What to do |
|---|---|
| 1. Let the glass cool | Wait until the glass and frame cool down after a hot shower. |
| 2. Ventilate the bathroom | Open a window or run the exhaust fan.Wear gloves if you have sensitive skin. |
| 3. Test a hidden spot first | Test a small corner first if you’re unsure about coatings, tint, or older hardware. |
| 4. Apply only where needed | Apply lightly to problem areas only (don’t soak the whole screen).Use a damp microfibre cloth to control where it goes. |
| 5. Leave briefly, then wipe | Leave for a few minutes.Wipe gently with a microfibre cloth or soft sponge. |
| 6. Rinse very thoroughly | Rinse with plenty of clean water to remove all residue. |
| 7. Dry the glass | Dry with a clean microfibre towel or squeegee to prevent fresh water spots. |
Tip: Don’t let the product dry on the glass. If it starts drying, rinse immediately.
What Not To Use Viakal On (Common Shower Risk Areas)
Even if the glass itself is fine, the surrounding bathroom materials might not be.
Avoid getting Viakal on:
Natural stone (for example: marble, travertine, limestone)
Decorated or printed glass
Damaged, scratched, or delicate surfaces
Any surface your bottle label says to avoid
Watch Out For Frames And Fittings
This is where people get caught out. Shower hardware and trims vary a lot. The safest approach is:
Treat the glass
Avoid the metalwork and seals
Rinse immediately if product gets onto fittings
What If Your Shower Screen Has An Easy-Clean Coating?
Some shower screens have a protective “easy clean” coating designed to repel water. Strong cleaners used too often or left on too long can reduce how well that coating performs over time.
Use Viakal sparingly
Keep contact time short
Rinse thoroughly
For regular cleans, use a mild cleaner and a squeegee
What If The Glass Still Looks Cloudy After Cleaning?
If you’ve removed limescale but the screen still looks hazy, it could be:
Etching (permanent marks in the glass surface)
Coating wear
Fine scratches from abrasive pads or gritty cleaners
Try this first:
Rinse again and buff dry with a clean microfibre cloth
Repeat one more light treatment (short contact time), then rinse thoroughly
If it still looks cloudy, you may need a glass polishing product or professional restoration. In some cases, replacement is the most cost-effective long-term fix.
How To Stop Limescale Coming Back
A deep clean is helpful, but prevention keeps it looking good.
Squeegee after every shower (30 seconds)
Dry the bottom edge and track where water sits
Microfibre wipe once a week
Avoid harsh abrasive scrubbers on glass
FAQs
Can I Use Viakal Every Day On Shower Glass?
Not ideal. Use it occasionally as a descaler, then maintain with gentler weekly cleaning and daily squeegeeing.
Can I Leave Viakal On For 10–20 Minutes?
It’s safer not to. Longer contact time increases the risk of marks, especially around trims, seals, coatings, or any slightly damaged surfaces.
Can I Use Viakal On Plastic Shower Screens?
Sometimes, but it depends on the plastic type and the specific product. Always patch test first and rinse thoroughly.
What’s Safer Than Viakal For Regular Cleaning?
A mild bathroom cleaner, a microfibre cloth, and a squeegee. Save Viakal for when limescale is visibly building up.
Final Verdict
Yes, you can use Viakal on shower screens, especially plain glass, and it can be very effective on limescale. Just use it carefully. Keep it controlled, keep contact time short, rinse thoroughly, and avoid sensitive nearby surfaces.
