Miracle’ Stainless Discs permanently banish toilet odour. Extraordinary though it seems, these discs really do work! Made from a special alloy of high-grade stainless steel, they neutralise odours as soon as they come into contact with air and water by catalyticaction, keeping the air fresh and clean. They contain no chemicals or fragrances to cover odours, but literally remove smells – and best of all, they last a lifetime. Hang one in the cutlery basket of your dishwasher or on the inside of the toilet bowl so that it makes contact with water every time you flush. Discmeasures 2 1⁄2” diameter.
