This product has a great smell and is very effective at keeping the toilet looking clean and smelling fresh, I would definitely recommend to my friends

Great for keeping your toilet clean and fresh. I do find that they don’t always completely dissolve which is a bit annoying. Apart from that they are great.

The blue stain is very obvious in your toilet water with this product. But does that really mean it’s also cleaning? I’m not so sure as I still feel I need to scrub my loo regularly

I like this as you can clearly see when it has run out by when the blue stops coming through. It smells nice and fresh too

Duck Blue refill toilet cleaner is a very good cleaner that is just so easy and it does an amazing job of keeping our toilet clean.

I really like Duck’s blue toilet cleaner under the rim refill block because it lasts and lasts and always keeps the toilet looking clean and smelling fresh.
