Pour 650 ml of warm water (35-40°C) into the bottle and add the toilet cleaner powder. Now close the bottle tightly and shake it vigorously for approx. 10 seconds. In the next 10 minutes, the powder should have dissolved and turned into gel.
Be careful before use: Some pressure may build up in the bottle as it dissolves. Therefore, open the bottle carefully and hold the opening away from you.
Another little tip from us: It can take a while for everything to dissolve completely. Individual particles may take a little longer. However, you can already use your toilet cleaner now without any problems. Everything should have completely dissolved by the next morning at the latest.
We recommend using the gel within 3 months after it has dissolved.
