Sterilizer Baby brezza: removal of white/brown plaque
White/brown scale is scale. It accumulates in devices and is the remains of minerals contained in water that do not evaporate when the water is heated. The higher the hardness of the water, the faster scale is formed. Scale is harmless, but looks unpleasant, is difficult to remove and can damage appliances or their components in case of excessive accumulation. It is recommended to descale the sterilizer at least once every 2 weeks to ensure its efficient operation. Follow the instructions below to properly descale your appliance.
100 ml of water + 10-20 ml of vinegar OR 100 ml of water + 1 teaspoon of citric acid
