The Best Mould Remover: Our Choices

Guide: Questions you should ask yourself before buying a Mould Remover

What is mould and how does it grow?

Mould is part of our environment. They can appear anywhere and can therefore also be found in flats, houses and gardens. You are probably also familiar with mould on food if you leave it for too long or store it incorrectly.

For mould to grow, it needs moisture. For example, mould in the home is often caused by condensation on walls or ceilings. The garden can also be infested with mould. For example, if you water excessively, mould can develop in the soil due to the waterlogging.

What types of mould are there?

There are a total of about 250,000 different types of mould on our planet, of which only 100,000 have been identified. In most homes, however, you will find five types of mould:

  • Green mould
  • Black mould
  • White mould
  • Red mould
  • Yellow mould

We have summarised how you can recognise each type of mould and more detailed information for you in a table:

Mould species identification characteristics and information
Green mould Green mould is the most common. This can vary in consistency and usually has a fluffy appearing coating on the surface. The toxin of this mould, gliotoxin, is not too dangerous, but can weaken the immune system
Black mould This type of mould is most commonly found in homes and is much feared as it is made up of different fungi and indicates a damp problem. Black mould can be dry and dusty as well as slimy and grey. In addition, this species is considered extremely toxic.
White mould Due to its colour, white mould is often undetected for a long time and can therefore spread unhindered. Identification features of this type of mould are a musty smell and the appearance of crawling animals such as woodlice. White mould irritates the mucous membranes of humans and thus leads to illnesses and health complaints.
Red mould Since red mould needs cellulose to grow, this type is mainly found on paper wallpaper. Bathrooms and toilets are also usually infested with red mould. The texture of this mould is usually dry, but can also be slimy. Red mould can contribute to lung damage.
Yellow mould Yellow mould is also often detected too late. In flats, yellow mould tends to be brownish, but is very rare in Germany due to the high hygiene standards. Yellow mould, like black mould, is extremely dangerous because it releases the toxin aflatoxin, which can lead to heart failure and liver cancer.

How do mould removers work?

Mould removers contain ingredients, such as chlorine, which ensure that the mould is destroyed.

There are mould removers that use other ingredients to avoid having to spray chlorine in sleeping areas or children's rooms. Basically, mould removers are disinfecting ingredients that specifically get to the bottom of mould.

How much does a mould remover cost?

The price range of mould removers is approximately between 2 and 25 EUR. So you should not expect to pay too much. Please note that the prices are per litre. If you need more, the costs will increase accordingly.

We advise you to hire a professional if you have large areas of mould infestation, as mould in living spaces can be very dangerous.

What alternatives are there to mould remover?

There are, of course, alternative home remedies to the mould removers on the market. Vinegar or vinegar cleaner is particularly popular. However, you cannot use this household remedy in every situation or on every surface.

The effect of destroying mould spores is also not quite as effective as with other mould removers.

What Types of Mould Removers are there and which is the right one for you?

Buying Criteria: These are the Factors you can use to compare and evaluate Mould Removers

To make it easier for you to compare the different mould removers, we have listed the following buying criteria that you should pay attention to when making your final decision.

You will find a short description of the criteria:

Ingredients

As already mentioned, mould removers can be distinguished from each other by the different ingredients. In the end, it depends on your personal preference.

Chlorine is not suitable for rooms where children play or you sleep. Therefore, you should carefully consider which agent is best suited for your situation.

Price

Since mould removers are produced by a large number of manufacturers, the price is also given in a narrower range.

Since mould removers are not overpriced, you can test for yourself whether the discounter is sufficient for you or whether it should rather be the brand manufacturer.

Contact time

The exposure time is an important criterion for comparing mould removers. The different types of mould removers can have an exposure time ranging from a few minutes to 1-2 days.

Ideally, the exposure time should be adhered to exactly in order to achieve the best possible result.

It is best to find out from the manufacturer how long the contact time is for their products.

Duration of effect

The duration of effect is another important criterion in your decision. Depending on the type of mould remover, reworking may be necessary, as is the case with alcohol, for example. Other mould removers only require a single application to the affected area.

Facts worth knowing about mould remover

How do I prevent mould?

Since mould occurs in damp and unhygienic conditions, you should always keep your living space clean and get to the bottom of dampness.

Prevention measure Description
Reduce moisture By airing your home daily or wiping the bathroom and shower dry after use, you can effectively reduce the moisture in your home and prevent mould.
Preventing water leaks If you have a leak in one of your pipes, it is advisable to call a plumber immediately and have the leak repaired. This way you will not be in danger of having an additional mould infestation in your house.
Avoid condensation When warm air meets cold surfaces, it condenses. This creates moisture, which is the perfect condition for mould. To prevent this, you should, for example, only ventilate in the mornings or evenings in summer so as not to let warm air into your home, or switch on the steam extractor when cooking. This prevents condensation and mould.

In the fight against mould, you should always eliminate the cause to prevent a new outbreak.

Can mould break out again?

Yes, mould can recur. If you remove the mould itself, but do not eliminate the causes of the problem, mould can recur. If the mould is in places you can't reach, your problem will get worse over time.

Is it advisable to hire a professional?

Basically, you should only fight mould yourself if you are dealing with smaller areas. If the infestation is so large that it exceeds one square metre or even affects entire walls, you should definitely call in a professional.

Mould removers are only suitable for smaller infested areas. If the infestation exceeds 1 square metre, you should seek professional help.
