I love using these toilet blocks in the tank of my toilet, I like seeing the blue water when I flush and the added bonus is it’s cleaning my toilet everytime. Would recommend

Duck blue toilet cleaner is a great way to clean my toilet that is very easy and quick with great results.This brand always delivers very good products .

I like to use these for the toilet bowls. they keep the toilets clean with every wash and it takes about 2 weeks to go there with harpic.

I love using these in my toilets at home. They freshen up the loo but also make them smell nice and keep them looking clean

We love our duck toilet cleaner because unlike the cheaper blue circle ones the ducks ones tend to foam up and clean the whole inside of the toilet with each and every flush, they also last just under 1 weeks.

I find these a much better option than an under rim option, both because it is a simple drop in the cistern process and because it takes away the visual temptation for a toddler to play with, which is a problem I have with the under rim ones
