No Nonsense Grout Cleaner 1Ltr

I bought this for really bad mould, basically black mould on grout. It didn't work. There is a chance that literally nothing would, so I've given it 2 stars instead of 1 because I'm just not sure if the task I set it, was possible. Maybe I'll come back and change the review if I find a solution.

I wasn't expecting miracles but I hoped for an improvement. Very disappointed. My husband had several goes with the product in the kitchen and I did the same in the bathroom. Thin and watery and even left on for twice the recommended time, it had marginal effect. Sadly, money down the drain, literally.

I bought this cleaner with high hopes, it is watery and works the same as the same kind of cleaner costing one pound. it has less than 5% ionic surfactants- whatever that is and seems to be suggesting by its name its really good- I found the opposite
