Parozone In Cistern Strongest Bleach for Toilet Block, Twin Pack, 2 Count (Pack of 10)

I find these to be the best in cistern toilet blocks. I don't like coloured water ones, because it is difficult to see if the bowl is clean or not. These don't colour the water and the smell is ok. The only problem is that they seem to be difficult to get because they are often out of stock. They seem very popular in the other reviews. and I highly recommend them.

I used PARAZONE BLEACH BLOCKS for many years until stores stopped selling them. I dislike BLUE water in my loo's .... I prefer it to be pristine and clear. I used ONE blue block 2 weeks ago and it just disintegrated in a couple of days with blue blobs in the pan, blue water really looks grubby too.A BIG THANK YOU to those who answered my question about the water colour of these. The older Parazone were white blocks so I was unsure about these.AT LAST I found the BEST bleach blocks on the market. I have read they don't last as long as some others BUT, I want the BEST QUALITY and PARAZONE is THE ONE, they keep everything very clean.They are brilliant and I highly recommend them.

Easy to use. Just pop one in your toilet cistern. Each one only lasts about a week in our house so a pack of 10 won't last that long. However being in a very hard water area and since using these we have had no limescale or pink marks in the toilet bowl and keeps the cistern clean. No colour and didn't notice any bleach type smell, just bubbles after flushing.

I bought these instead of our regular ones and they are a lot better than the regular ones so I will be buying them again

Good

Really good at cleaning toilet and noticed significant reduction in lime scale build up. But only lasts for five to six days before total dissolve, hence the 3 star rating. Package claims replace every 4 weeks or when foam fades (5-6 days for me in a hard water area). No way this product lasts four weeks but good for 5-6 days, so I’d give it a five star rating if the price was dropped by 75%.

Can't get these anywhere got a good deal so brilliant 👏

Good value
