Yes, vinegar kills mould.
White vinegar, in particular, is often used as a DIY mould removal method due to its effectiveness and non-toxic nature.
What is Vinegar?
Vinegar is a liquid consisting primarily of acetic acid and water. It is produced through the fermentation of ethanol by acetic acid bacteria. This process converts alcohol into acetic acid, giving vinegar its characteristic tangy and sour taste.
Why Does Vinegar Kill Mould?
White vinegar has an acetic acid concentration of 5–8%, making it strong enough to kill mould. It is an ideal solution for DIY mould removal because it is non-toxic and highly effective at killing mould on contact.
Does Vinegar Prevent Mould Growth?
While vinegar is good at killing mould, it does not provide ongoing protection against mould growth. Its effectiveness is limited to the time it remains wet. Once it evaporates, surfaces are left vulnerable to new mould growth. To ensure long-term mould prevention, engaging specialists like Mould & Hygiene Solutions is the best approach as they use advanced techniques to prevent mould from returning.
How to Use White Vinegar for Mould Removal
- Pour undiluted white vinegar into a spray bottle.
- Spray it directly onto the mouldy area.
- Let it sit for at least 1 hour to allow the acid to break down and kill the mould.
- Scrub the area with a brush or sponge and rinse with warm water.
- Allow the surface to dry completely.
- Repeat steps 2–4 if necessary.
Can I Use Vinegar on All Surfaces?
While vinegar is a powerful and natural mould remover, its high concentration of acetic acid can damage certain surfaces. Avoid using vinegar on:
- Natural Stone Surfaces: Such as marble or granite, as vinegar can etch the stone.
- Wooden Surfaces with a Wax Finish: It can strip the wax and cause discolouration.
- Cast Iron and Aluminium: Vinegar can cause corrosion on these metals.
- Stainless Steel: Prolonged exposure can lead to damage or dullness.
Summary – Does Vinegar Kill Mould?
Yes, vinegar does kill mould. However, for serious mould problems, it is always best to engage a professional that not only has the capacity to kill mould but also provides ongoing protection against mould growth, such as Mould & Hygiene Solutions. Using vinegar is a viable option for small, surface-level mould problems, but it often falls short when tackling significant mould issues.
