The problem with most mould removers

Typical mould cleaners rely on bleach-heavy sprays that mask stains instead of removing them. They evaporate too fast to be effective, failing to soak into porous grout or silicone where mould thrives. The result? Stains keep coming back, and the smell only hides the problem—not solves it.

6 reasons why we're the best

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.

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.

I honestly didn’t expect this kit to work so well. But seeing that first streak-free, mirror-bright finish as I checked my progress almost brought tears to my eyes. I recommend this to everyone.

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.

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 👍

It worked really well . My daughter was happy with the end product

They work really well

Best squeegee, better than the ones from the hardware stores and supermarkets

Does exactly as it claims to do

Using bore water makes shower door and taps yuky Dissolver works well Thanks

Great mitt does a great job on the glass.

I have now used the Calcium Dissolver on my house windows as the bore water had covered them with a white film. This product is brilliant. I had previously tried all different products e.g: vinegar, scourers, metho, turpentine etc nothing worked until now. Highly recommend the calcium dissolver, just dampen a cloth with it and wipe over no elbow grease required. Thank you Clean Screens.

Well here I was debating with myself for months whether to buy yet ANOTHER cleaning product that supposedly cleans away mould and water stains. This product was absolutely amazing, it cleaned the mould in the silicone of shower screen away right before my eyes, like magic. I couldn't believe it, so there's that, then the water stains on my dark tiles, how awful and problematic they have been to me, but once again the product for that was awesome. I had to do it twice but it came up a treat. So THANK YOU from me for your excellent cleaning products. I will definitely be buying on repeat as needed.

Fantastic

Works well on tiles

Great product

Easy to use and works a treat!

Great product, does exactly what it says!

Seems to work 👍

Its just like what they say in the videos. Most effective product for that calcium.

It did a really job. My shower screen is really old and was caked with calcium and hard water stains. It's not completely gone, but 99%. I was ready to give up before this.

Fantastic products with great results!

Happy with the Mould Remover twin pack.
Will order again in the future

Terrific did the job !!

Will buy again

Just received mine and worked brilliantly. After years of trying to clean calcium buildup off my tiles, finally this actually works. I’m thankful I’ve found this, as I’ve wasted so much money and time,...

No regrets

I was using toilet bowl cleaner until I got my delivery of this stuff... a bit expensive but does a great job.. easy to apply, easy to remove.. good product.
