The problem with most calcium removers

Most calcium removers rely on diluted acid formulas that evaporate quickly and barely scratch the surface of thick mineral build-up. They may bubble and fizz on contact, but the real problem—layered hard water stains—remains bonded to the glass. Without a gel that clings and penetrates, you’re left scrubbing endlessly for mediocre results.

Engineered in labs—not DIY recipes—our precision formulas target and remove deep mineral films.
Perfected across 35,000+ real bathrooms, not just foam tests—guaranteed commercial-grade performance.
Erases trace molecules at the molecular level—no hidden residue to attract soap scum.
Nano-coating repels water and grime, delivering up to 5 years of lasting protection.
Balanced, biodegradable, and non-toxic recipe—powerful cleaning without harsh chemicals or surface damage.
One easy Kit replaces costly pros and endless scrubbing—restore showroom shine in one treatment.

01

Meet The Founder

Twenty-plus years on the tools taught Brendan one ruthless lesson: most “specialty” cleaners and sealants break down when the job gets real. Tired of re-doing work because off-the-shelf products couldn’t keep up, he built his own. Every formula you see here started life on a commercial site, under Brendan’s watch, solving problems for architects, builders, and facilities managers before it ever reached your shelf. What you’re buying isn’t hype—it’s a tradesman’s reputation in a bottle.

02

Scientific Backing

Brendan partnered with materials chemists and independent test labs for a relentless four-year R&D sprint: 200+ iterations, accelerated-aging chambers, abrasion rigs, and real-world pH abuse on limestone, marble, and tempered glass. Only the blends that hit professional-grade durability and consumer-grade ease made the cut. The result: lab-verified performance, priced so everyday users can get pro-level results without calling in a contractor.

03

From Job-Site Headaches to Home-Use Heroes

The company was born the day Brendan realised “good enough” products were costing tradesmen—and homeowners—time, money, and credibility. He left the sub-par stuff on the shelf, rented after-hours lab time, and built a range that closes the gap between commercial performance and household convenience. Today we’re still obsessively field-testing every batch, still pushing the science, and still driven by the same promise: if it doesn’t outperform everything else you’ve tried, we won’t ship it.

Love this product, my shower screen looks brand new again. Grout has also become white again. Worked wonders in the washing machine.

I couldn’t believe how well this product works

Very good product, easy to apply. I live in a town with very hard water so was desperate to find a product that works. Depending on how "clean" the glass is, depends on how much "elbow grease" is required. I did one of my showers with good results. Took me a couple of hours. Started on my second but need another cleaning disc. So will get a few more of these and continue with the 2nd shower. Also used on the shower wall tiles and they came up good too. So far, happy with results.

I have tried many cleaners before but after using this product I can definitely see an improvement. One pellet was not enough so I have ordered more - (we have a large screen) and after another application I think we might have very good success.

We had given up on getting s clean shower screen. This kit restored it to brand new. Absolutely amazing. Highly recommend

Amazing. The mildew/mould just disappeared!

Amazing product…love love love ❤️

Absolutely loved it, we have really hard bore water, the glass screen has had years of water stain I didn’t take any before or after 😫, I was eager to start, but my mum in law thought I put in new glass for her while she was away, so I’d say it worked pretty well, was only 1 panel and a small 3 panel slide door, I used the whole tablet pretty much you couldn’t see through glass it was that bad, so to bring it back like new, was an epic feat. 5 star ratings from me. Thank you so much 😊

Company assured me this product was safe to use on coloured grout. It isn't. It has left grey grout cloudy in patches were it's stripped the colour from the grout.
Do not use coloured grouts.

This product is excellent

Love it. Dose a fantastic job, very easy to use.

Great squeegee..love it.

WOW….what an amazing product! 10/10. I have tried so much products and hacks and wasted so much money and time.This is a life saver for my cleaning business. A HUGE THANKYOU!!❤️

Have never seen anything work like this before… amazing product!

Absolutely amazing product! The only one that works quickly, effectively and ‘does what it says on the tin!’
Highly recommended

Best glass cleaning product ever. I've tried a bunch of ways to get build up off my shower screens and nothing else works like this. Both the gel and the pellet are awesome.

Amazing better then all the others ive wasted money on

These are great, pop out the old one and in with the new. I've got two very large showers with glass on 3 sides of each so I needed one per shower. Put the effort in with the circular motion and you will get great results.

I bought the Calcium dissolver for a very very built up shower screen. It did take a lot of the marks off and only left very small tear drop outlines from water damage. I decided to use the pellet to clean away the remaining grime. It has taken a few goes but the shower is looking clean and sparkly now.

This has been the best of all the products I have tried but it didn’t remove all the hard water deposits from the shower screen. I will keep trying with the hope that more will be removed over time

Perfect results and saved from more hoursof fruitless cleaning

Awesome product. Best thing I've found for cleaning shower screens.

These are fantastic for cleaning shower screens. They removed more of the calcium buildup than anything else I've ever used. Highly recommended.

Loved that it temoved the mould without the smell of bleach.

This calcium dissolver is brilliant, my shower screens are so clean 👌 it's amazing. I have tried so many different products which didn't get the build up of, but this one did! and with very little effort no scrubbing. Definitely recommended this 👍
