Does Ammonia Kill Mold?

Ammonia is a common household cleaner that has been used for years to clean many areas of a home including bathrooms and kitchens. But can Ammonia kill mold?

Ammonia can be used to kill mold in the home. However, it’s only effective at killing mold on nonporous surfaces as it can damage porous materials like wood or drywall. If you’re killing mold on a porous surface, it’s best to use a product with Sodium hypochlorite.

Tips for preventing mold growth

There are certain things you can do to prevent mold growth. These include:

  • Keep a clean home and dry the air regularly. Mold spores are easily spread by dust and debris. You should also keep your home as dry as possible to prevent moisture from accumulating in the air and causing mold growth.
  • Make sure that you have enough ventilation and air circulation in your house. If there is too much moisture in the air, it’s much easier for mold to grow.
  • Do not dry clothes on doors or near windows, as this can lead to mold growth in your home.
    • If you find mold growing on objects such as your walls or under your carpets, it’s best to remove it immediately before more damage can be done by leaving it behind for longer periods of time.
  • Check for leaks in your home’s plumbing system and fix them as necessary to prevent mold growth.
  • Make sure windows are properly maintained, especially during the hot summer months when it may be easier for the rain to seep into your home through cracks or holes in the window frames or casings (especially if you have older windows).
