So, does alcohol really kill mold?

In truth, it does, but with limited effectiveness – which is why it should only be used as a last resort. Another major downside is that it does not kill mold spores. In other words, there are far better mold removal options available.

On the plus side, alcohol excels at removing most types of mold from leather goods, books, and fabrics. It also doesn’t leave surface areas wet because it dries quickly and leaves no odors behind.


Which types of alcohol can be used?

Generally, any type can be used, but for best results, stick to low-grade vodka or isopropyl alcohol (rubbing alcohol).

Why low-grade vodka?

When it comes to vodka, the bottom-shelf variety will give you the best results because it’s less distilled and therefore has higher amounts of acetaldehyde, which is toxic to mold and other types of fungi.

Why isopropyl alcohol (rubbing alcohol)?

Isopropyl alcohol is commonly used as a disinfectant and antiseptic. Should you choose to use this alcohol for mold removal, then pay careful attention to the purity levels.

Purity levels generally range from 60% to 90%. One would think, the higher the alcohol concentration, the more effective it will be at killing mold, but that simply isn’t true.

Use 70% for best results. Anything less won’t be strong enough to get the job done and anything higher will cause the alcohol to evaporate too quickly before it gets to kill the mold.


How to kill mold with vodka

Materials needed: What we’ll need is a pair of gloves, a bottle of cheap vodka, a spray bottle, a dish towel, and a hard-bristle hand brush.

1: Pour the vodka into the spray bottle. There is no need to dilute with water.

2: Spray the vodka solution onto the mold area and leave it on for about 10 minutes.

3: Spray some more vodka onto the mold and gently brush the mold off with the hand brush.

4: Spray a bit more vodka and wipe it dry with a dishtowel.


How to kill mold with isopropyl alcohol (rubbing alcohol)

Materials needed: What we’ll need is a pair of gloves, a bottle of 70% rubbing alcohol, a spray bottle, a dish towel, and a hard-bristle hand brush.

1: Pour some of the 70% rubbing alcohol into the spray bottle. You must use no less than 70% because anything under and it might not be strong enough to kill the mold. If you have rubbing alcohol higher than 70%, then dilute it a little bit with distilled water.

2: Spray the solution onto the mold area and leave it on for 10 minutes or so.

3: Spray more onto the mold and gently brush it off with the hand brush.

4: Spray a bit more and wipe it dry with a dishtowel.
