If you want your bathroom faience to shine extra, you should clean faiences frequently with the Macromax Life&Brush cleaning brush. Before cleaning faience and ceramics in your bathroom, turn the faucet toward hot water and let the bathroom fill with steam for a while. The steam will make your job easier as it will soften the dirt.
Scrub the windows of your shower cabin with Macromax Clean&Window glass cloth and lemon oil twice a month. You will see that your windows do not retain water.
