Bio Clean Hard Water Stain Remover

Brilliant works really well our shower doors now look brand new A+++

The only reason it’s not a 5 star is the fact it’s a paste and not a spray. Apart from that it worked amazing, I had tried EVERYTHING on my shower door, and the hard water stains were not moving. This worked first time within 10 minutes it was literally all gone! I would suggest applying with a cloth first, rub this in, then use a scourer or a tough sponge to spread it around and saves some product. Smells great also. Not great value for money because of it being in paste form, but overall works a charm.

This is good stuff and dose work. Needs hard work put in for those tough water marks

Did not work at all. Tried it four times and still no results. Would not recommend.

It works. I’ve tried many other brands without luck. I then tried this with a non scratch sponge and it wasn’t sufficient but this with a drill and brush attachment did the job. Without the this product, the brush attachment was insufficient on its own

I bought this product as it seems some people are really into it, especially cleaners in the USA. So after searching for it, I did come across it. When I saw the price, it took me a whole week to decide to buy it. I already knew it would be a paste, but it takes so much product to achieve results, if you even get any. I have been a cleaner for years, and I use spray cleaner limescale remover (bio), which is brilliant, but no harm in trying something new or even better. I would never repurchase it. You can find a cheap one that does the same work. The product to clean the shower glass can take far too long, especially at clients' homes and when neglected too long, they expect a miracle. This is a no for me.

Works well on glass

Quite disappointing for the price. It does bless hard water stains but definitely expected complete removal for this price
