– New Bloo Toilet Blocks, Pack of 4, Toilet Limescale Remover Cistern Block, Toilet Cleaner Block with Cleaning and Foaming Action, Toilet Fresheners – Lemon

Great blocks for placing in toilet cistern. Last for ages and give a clean fresh smell to your toilet with every flush. Easy to use - just pop one block in the cistern. Very effective and convenient.

Very effective at clearing the limescale,and any other residue. Best used with a brush,first time,if you have a settled residue problem. The water remains clear as they are free of colored dye. The price is more than reasonable as the blocks are each active,for about a week,depending on usage of the Turdis.

Nicer than the blue version, but it takes a few days to kick in. The scent is nice. These are replacements as I've run out. I'm not too sure how effective they are at removing limescale, but since I live in a hard water area, anything that keeps it to a minimum is fine by me.

Fine but pricey.

Good price, Nice smell, cleans the toilet, however it messes with the flushing system as the grit from this clogs it up & system will just keep running water, so much water!!! Such a shame I won't be buying this anymore, I'm looking for something else it isn't gritty!

Easy to use smellies great and good for cleaning the toilet bowl

Very good item, last well,Keep loo clean and fresh

Does the job
