If the foam doesn’t foam as expected, it could be due to water that’s too cool or too little water. Make sure to use at least 1 liter of very hot water (at least 80°C).
Important: Shake the bag well before opening or loosen the powder with your fingers. Then, cut the bag completely at the top so you can easily pour out the entire content. Pour the powder into the toilet as close to the water surface as possible immediately after adding the hot water – this will start the reaction optimally, and the foam can unfold properly.
If there are still residues visible after use, it’s often due to older, stubborn deposits like limescale or urine stains. In this case, it helps to extend the soaking time up to 30 minutes and then clean with the brush. If needed, you can also perform a second application.
