Toilet Cistern Blocks FAQ
Q: How often should I use one of the blocks?
A: As often as necessary. As soon as the water stops turning blue after the first use, then another block should be used. This ensures continuous cleanliness of the toilet.
Q: I accidentally dropped the block into the bowl, is this a problem and will it continue to work in the bowl?A: Recover the block and do not flush, then place in the cistern. Flushing could potentially make the toilet block wedge into the piping and block the toilet. The effectiveness of the product will not be seen in the bowl.
