Hello! I have recently cleaned my bathroom with cleaning vinegar and baking soda paste and I have noticed that there are now white stuff in the between the bathroom tiles. I tried cleaning it with a mixture of parts water and vinegar then scrubbing it with a brush and a baking soda but, unfortunately, it didn’t work. I also tried using Selley’s Mould Remover but didn’t work. Do you have any recommendations? Especially on how to prevent this from happening? Thanks!
