Homemade mold killer

Updated February 21, 2017

Mould can easily develop in homes where there tends to be a lot of moisture and a lack of sunlight. While a variety of retail products kill mould and mildew, these items can be costly, and many times priced out of your budget range. Instead, create your own homemade solution using inexpensive ingredients that are most likely already in the home.

Mould killer for cement and concrete surfaces

Bleach is a disinfectant that kills mould and mildew. In a spray bottle, mix a diluted solution of 711 ml (3 cups) water and 237 ml (1 cup) bleach. Spray onto the mould and mildew once daily until all mould has been killed and diminished. Repeat as necessary to keep mould and mildew development at a minimum. Do not let bleach come into contact with skin, as it can irritate and sometimes burn skin (wear protective gloves). Also provide proper ventilation by opening a window when using bleach, as fumes should not be inhaled. Ammonia is another effective mould removal cleaner that will kill mould on contact. In a spray bottle, mix equal parts of water and non-sudsing ammonia (available at any supermarket near cleaning products). Spray the solution directly onto the mould, and it will quickly begin breaking apart and dissolving. Spray the solution onto the mould once daily until all signs of mould and mildew are gone, and repeat when necessary if mould redevelops. As with bleach, provide proper ventilation when using this item, as fumes should not be inhaled.

Mould killer for showers

Mould can also develop in showers, where moisture and steam can cause mould to grow at a rapid pace. Simply mix a solution of 474 ml (2 cups) water and two squirts of washing up liquid, and spray onto the mould as it begins to develop. If this does not completely dissolve the mould, follow up with the ammonia solution mentioned above.

All-purpose mould killer

Vinegar is a mild, inexpensive cleaning agent that is safe for nearly all surfaces and breaks up mould and mildew quickly. From house siding to granite countertops, you can use a simple combination of 474 ml (2 cups) water and 237 ml (1 cup) distilled white vinegar in a spray bottle. Spray directly onto mould and mildew as it develops, and add an additional 20 drops of tea tree oil or lemon essential oil for a scented cleaning product.
