“Quite simply this very expensive product does not work. Waste of money which hurts! I purchased this product on the reviews with high hopes but no difference to the shower area, no matter how long it is on and how I scrub it. It is a relatively new shower so not a lot of mould but mould none the less. The smell is TOTALLY over powering that lingers for hours and has to be rinsed of again and again. Not happy.”
