Is Vinegar or Bleach Better for Killing Mould?

The team at I-sells recognise the discomfort, destruction and danger that can be caused by inadequate ventilation, along with environments that are not properly maintained, that can become susceptible to mould.

Mould can and will spread if left unattended, but it can be dealt with in a variety of ways, in this blog, we will be discussing “‘is vinegar or bleach better for killing mould?”

But first, let us explain how mould forms.

How does mould form?

Mould in your home generally occurs as a result of condensation.

Condensation occurs when heat and moisture in the air are confined to a certain area, as this heat tries and fails to escape, droplets of water are created on cold surfaces. A good way to think about this is having a hot shower on a cold day and not opening your window.

The reason condensation creates mould is that a damp and humid environment is the optimum condition for mould to grow. In regards to windows, it is a big problem if there is mould on your windows (it can usually be found in the corners of the windowpane or the walls connected to the window).

The true danger of mould is that its particles can travel through the air without us seeing it, incidentally, this means opening a window with mould on it runs the risk of that mould being blown inside your room alongside the fresh air.

That being said, condensation is not the only cause of mould, it can occur from leaks in the structure of a building too. Aside from this, mould can develop from out of date food, which spreads to other food that is left near it.

Mould Exposure

moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances.

Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Moulds can also cause asthma attacks. if you have damp and mould in your home you’re more likely to have respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system.

On some occasions, you may not have to break the bank in order to remove mould, it could just be a case of treating it. And luckily there are two household items that can effectively combat mould, and are worthwhile options to try before investing in mould treatment solutions. These household items are vinegar & bleach.

Realistically, both options are viable when it comes to killing mould. However, vinegar holds the edge, although bleach will kill mould on the surface level, it is unable to penetrate into pourus surfaces like wood due to its thick consistency.

Although surface level removal is a good enough temporary measure, the mould will return as it can grow beneath pourus surfaces. However, vinegar is able to penetrate pourus surfaces and can therefore destroy mould from its ‘roots’, making it a viable option to try.

Is bleach better than vinegar?

In some situations this may be the case, though with bleach, there are definitely more safety precautions to be taken, this is because bleach can react with other chemicals that can create harmful gasses that can cause mild irritation all the way to conditions that require hospital treatment.

Even if bleach is diluted, you must still wear gloves & preferably a mask and goggles when handling. Vinegar is still slightly acidic to the skin so it is recommended to wear safety equipment, however the potential hazard of noxious gasses isn’t as prevelant with vinegar.

Using Vinegar to destroy mould

What you will need:

  • White vinegar
  • An Empty spray bottle x2
  • Baking Soda
  • Scrub pad or brush
  • Mask, gloves, goggles.
  1. Apply your safety equipment before commencing
  2. Pour the vinegar into the empty spray bottle, then use the spray bottle on the moulded area, be sure to spray directly onto the mould. After spraying, leave it for an hour minimum.
  3. Add a teaspoon of baking soda and two cups of water in your spare spray bottle, shake thoroughly. This is your baking soda scrub.
  4. Spray the scrub directly onto the mould just as you did with the vinegar, then scrub the area, the baking soda helps to remove any stains caused by the mould. Rinse the area with warm water after the scrub.
  5. Spray the area once more with your vinegar or baking soda solution, (either is fine) then leave the area to air-dry.
