Do not forget that many cases of mold occurancs within the premises and are not always visible. Therefore, it is important to pay attention to smells of mold in your home. Depending on the porosity of the material, the mold can be installed more or less superficially. The less porous the material, the easier it is for cleaning (plastic surfaces are easier to clean than walls). Before cleaning, if the area is large, prefer to hire a specialized company in cleaning mold and cleaning mildew.
