A complete waste of money
I have a brand new cassette toilet which I used for the first time at the beginning of 2017. I used green sachets for the bottom tank and pink rinse for the top. I used the toilet for urine only, emptying it weekly for 12 weeks. Washing it out thoroughly with fresh water after each emptying. I purchased the tank cleaner as a simple routine clean before another winter trip away. There was quite a build up of what I take to be calcium. The tank cleaner failed to remove the scale following the instructions carefully. I subsequently attempted to use the cleaner undiluted. That has failed too. My brand new cassette toilet is now caked with calcium and I have no idea how to remove it. This product did not work at all.
