On a mission to change bathrooms worldwide.
I’ve tried dozens of cleaners with zero luck. This kit erased stubborn stains in one go, and maintenance a breeze thanks to the nano-coating. My bathroom looks brand new!
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.
If you've tried other products (and they didn't work!) just be glad you finally found this. So so happy with how my shower turned out.

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.
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.
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.

Wow I did not think anything would help restore my grout other than replacing it! But I was wrong the Mould & Mildew remover worked wonders. Most mould came away on first application and the rest worked after a second application. Definitely recommend this product and will buy again for any future mould problems.
Did a great job of cleaning the mould from our tiles. A strong bleach-like smell though. Used in conjunction with the deluxe cleaning products. I see some residue on the tiles from the cleaning product but definitely cleaner.
The mould remover is a great product. While it didn't remove the mould from the silicone, it did an excellent job of brightening the grout and made it look much cleaner.
Absolutely amazing n I have tried so many that claim they work n this one does. I would highly recommend. Would not use anything else. Well priced too. Thanku Clean Screens.
Great stuff, actually a product that works and simple and easy to use with no offensive smell.
I received my package damaged it appears it’s leaked during transport
Great, easy product to use.
Very impressed. It certainly does the job
A product that actually works! Amazing
After trying many bathroom and shower products, it's great to finally find ones that actually work and don't leave an overpowering smell. Easy to order, easy to use and customer service has been fantastic. Have already made my second purchase and will be definitely making more.
It worked as stated in the description, glass came up really clean.
Very impressive. Great product.
It really does get rid of the mould
I love this product. It works exactly how it states it does. Will definitely order this again.
This was the first product I have tried that has actually worked on long-term mould in grout. Some areas required two applications but it has certainly made a difference. I have now used the grout sealer to hopefully make sure I don't have to treat the mould again for a while!
Expensive for the size of the bottle but it does work
Fantastic
such an amazing product, it really works, small odour but well worth it.
Fantastic product and highly recommended
Moved into a new place grout needed a clean up very impressed removed everything from the grout
Highly recommend
This product is amazing. I really could'nt believe how quickly and efficiently it worked.
I am very happy with the mould, grout and mitt kit that I bought from Clean Screens. Most of the mould in our showers were removed on the first go. I just have a few tough spots of mould left and I will tackle those next weekend before using the grout spray. I will definitely buy more products in the future from Clean Screens.
Works as described n very impressive as it moved a lit of mould in our silicone in shower.
Does remove the mould
Loved this product
Was amazing grout is all white now
Exceptional product
I have been using this for over a year now and I get great results.
What’s also great is the service. Never had an issue ordering or having to chase delivery.
Very important to deal with a service minded company.
This is great. Love the nozzle that allows you to drag along the grout to minimize waste
Easy to use and clean well without the scrubbing
I have only used once at this stage, yes it worked well on areas i had concerns with.
My shower seems plagued by pink biofilm, and even after scrubbing, the grout stains very yellow. This did a great job of whitening it back to looking new! It was runnier than I was expecting, so it was a bit tricky to get into the recessed grout. I was worried that it would slide down the tiles, and it did a little bit, but still got the job done. It doesn’t smell as strongly as bleach, but as someone who is sensitive to smells it still smelled strong to me, even with plenty of ventilation. Make sure you wear gloves when washing it off, otherwise the smell clings to skin despite frequent handwashing.
