Idisan Hygienic Spray. It is useful for eliminating bacteria, viruses and impurities from the skin and surfaces. The spray formulation makes it very convenient to clean the mask after use. Idisan spray has an alcohol concentration higher than 70% and therefore also has activity against viruses and bacteria. It is enough to do some spraying on the mask, especially from the outside. While spraying the product, we recommend holding the mask by the straps to avoid contaminating it with your hands. After spraying with Idisan, it is advisable to leave the mask in the air for at least 30 minutes before using it to allow the product to exert its cleansing effect and evaporate.
