Disadvantage: The bathroom smelled strongly of chlorine for 2 days - as in the indoor pool. Fortunately, we have a bathroom window and were able to ventilate continuously. Meanwhile the smell is gone and the bathroom shines like new.
IMPORTANT: chlorine bleaches the silicone. This means that points are brighter. When plotting the liquid unevenly (because eg. Droplets form) will be there, of course, more bleached.
For me no problem, because my bathroom is 100% white. Therefore, it was a good purchase for me.
If necessary, I will use the product again.
