Why it won't come off
You scrub and scrub.
The glass stays cloudy.
Those white marks aren't dirt. They're minerals left behind by hard water, and they bond to the glass. Everyday sprays and wipes just slide over the top.
01
Sprays can't shift it
Bathroom cleaners lift grime, not the mineral layer that's built up on the glass over months and years.
02
DIY hacks take forever
Vinegar and baking soda mean hours of soaking and scrubbing for a small improvement, if any.
03
So it keeps building up
Every shower adds another thin layer, until the glass looks permanently frosted and you think it's ruined.
The cerium oxide difference
It polishes the stain off. Not just the dirt.
Cerium oxide is the go to compound for polishing glass. Paired with citric acid, it breaks down mineral build up and buffs the glass back to clear. Drag the slider to see the difference on real shower glass.

How it works
3 steps. Clear glass in under 30 minutes.
1
2 minutesShake and apply
Shake the bottle for 10 to 20 seconds. Pour a little onto the scourer pad and work it over the glass in circular motions.
2
10 to 20 minutesLet it sit
Leave it to break down the mineral build up. Then go over the glass again with the pad, focusing on the worst spots.
3
2 minutesRinse it off
Rinse with water or wipe clean. Very heavy or years old build up can need a second application.
Always read the label before use. Spot test first. Contains 20% cerium oxide and 5% citric acid, so avoid contact with skin and eyes.

Questions
Before you buy
Will it work on really old, heavy stains?
Yes, that's what it's made for. Most glass clears in one application. Very heavy or years old build up can take a second round, and the Mini Electric Scrubber kit saves a lot of elbow grease on big jobs. And if you're not happy, you're covered by our 60 day money back guarantee.
How does Subscribe & save work?
Choose how often you want it delivered and you get 15% off this order and every delivery after it. You can skip a delivery, change the frequency or cancel at any time from your account. There is no lock in and no cancellation fee.
How long does it take?
A couple of minutes to apply, 10 to 20 minutes to sit, then a second pass and a rinse. Most showers are done in under 30 minutes.
Which size should I get?
250ml is great for trying it on one shower screen. 550ml is our most popular size and suits most homes. 1100ml (2 x 550ml) is the best value per ml if you've got several showers, windows or a pool fence to do. Unopened, a bottle lasts around 2 years.
What surfaces can I use it on?
Glass, including shower screens, doors, windows, pool fences and balustrades, plus ceramic and tile. Not suitable for tinted or coated glass, plastic, acrylic, natural stone, painted surfaces, or polished or delicate metals. Always spot test first.
What are the ingredients?
It contains 20% cerium oxide and 5% citric acid. The full Safety Data Sheet (SDS) is available on request from contact@glassguard.co.nz. Always read the label before use.

Orders dispatch from Auckland within 1 to 2 business days. Delivery is 1 to 3 business days for metro areas, 3 to 6 for regional and 3 to 8 inter island. Shipping is free on orders over $75.
