Rated 5 out of 5 by from Heavy limescale remover. Used for limescale removal on a toilet. The limescale was very heavy, thick and caked on. Having tried other cleaners which did not touch it this cleaned it off like new in minutes. Wish i had used this first.

Rated 4 out of 5 by from Good for the money As the title says, its good for the money, works well and cheap enough. It is an acid so be careful with the use of it and wear PPE. It has a good child proof top on it which I think is wise. Read the instructions!!!!
