Why it keeps coming back

You clean it. Two weeks later,
it's back. Sound familiar?

Most mold products are sprays. They run straight off grout and silicone and evaporate before they can reach the mold 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 mold 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 mold at the root. Drag the slider to see one application on real grout.

Questions

Before you buy

Will it actually work on old, stubborn mold?

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?

One 10 fl oz tube handles a typical shower. If you're doing a full bathroom, or bathroom plus laundry and window frames, go for 2 or 3 tubes. Both save 20% per tube 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, countertops, 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.com. Always read the label before use.

How fast is shipping?

Orders dispatch from our US warehouse within 1 to 2 business days. Delivery then takes 2 to 7 business days. Shipping is free on orders over $69.

What if it arrives damaged?

Send us a photo at contact@glassguard.com and we'll ship a replacement, or refund you in full if a replacement isn't available.
