When tight Canadian homes meet cold Canadian winters, condensation, mould and mildew growth can develop. It’s actually quite common, and this is why spring is prime time for killing mould and eliminating mould staining that developed over winter.
The most likely locations for condensation-induced mould growth include window frames, bathroom ceilings and interior walls behind furniture, but remember two things. First, it’s important not to use bleach for killing this kind of mould. Even the EPA recommends against using a bleach solution to kill mould because it’s too harsh on people and because it can’t reliably kill mould spores that have penetrated porous surfaces such as wood or drywall. What you want are bleach-free products that have been tested and registered as safe and effective fungicides. For example, Activox Deck & Patio Cleaner is a two-part, oxygen-based, mould, algae and mildew remover. It's ideal for decks, patios, wood, concrete and other surfaces, and revitalises outdoor surfaces to their original appearance.
