Why it keeps coming back
You clean it. Two weeks later,
it's back. Sound familiar?
Most mould products are sprays. They run straight off grout and silicone and evaporate before they can reach the mould growing underneath the surface.
01
Sprays run off
Liquid slides down vertical tiles and silicone in seconds, so the contact time is too short to do the job.
02
Scrubbing only hits the surface
You wreck your wrists and your grout, and the mould rooted inside the porous surface stays put.
03
So it grows straight back
Leave the root behind and those black spots are back after a few steamy showers. The cycle repeats.
The gel difference
It stays put. So it keeps working.
The thick, cling on gel sits exactly where you put it for hours, soaking down into grout and silicone to get the mould at the root. Drag the slider to see one application on real grout.

Questions
Before you buy
Will it actually work on old, stubborn mould?
Yes, that's what it's made for. The gel stays in contact for 3 to 5 hours, much longer than a spray. Very old or deep staining can need a second application, and a light pass with an abrasive pad helps on the toughest spots. 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?
About 2 minutes to apply and 2 minutes to wipe off. The gel does its work in between, over 3 to 5 hours. Do not leave it on for longer than 5 hours.
Which size should I get?
300ml handles a typical shower. If you're doing a full bathroom, or bathroom plus laundry and window frames, go 600ml or 900ml. Both save 20% per ml compared with single tubes.
What surfaces can I use it on?
Tile, ceramic, glass, plastic and silicone, including grout, sinks, bathtubs, toilets, window frames, doors, pool areas, solar panels, ovens, benchtops, washing machines, fridges and dishwashers. Not suitable for unsealed wood, fabric, leather, natural stone, painted surfaces, or polished or delicate metals. Always spot test first.
What are the ingredients?
A full ingredient breakdown and the Safety Data Sheet (SDS) are available on request from contact@glassguard.co.nz. Always read the label before use.
How fast is shipping?
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.
