Advice: Questions to Consider Before Buying a Toilet Cleaner

When is a toilet cleaner necessary?

A toilet cleaner or toilet cleaner is used to thoroughly clean the toilet.

In contrast to an all-purpose cleaner or often used bathroom cleaner, with which you clean the outside toilet, the inside of the toilet is cleaned with a toilet cleaner.

You let a toilet cleaner work for about 10 minutes and then wipe it away. You can use it to remove germs, urine scale, limescale deposits and other dirt. They consist of acids or chlorine, surfactants and fragrances.

A toilet cleaner normally has a pH value of 1. The chemical ingredients in a toilet cleaner can cause irritation and chemical burns.

How often should I use toilet cleaner?

Urine stone or limescale deposits do not always form during everyday use. With the usual cleaning of the bathroom and toilet, the inside of the toilet should still be cleaned so that you have a hygienic and clean toilet.

This makes it beautiful, clean and has a pleasant smell.

The more you clean, the less stubborn dirt can occur.

If your toilet is not used excessively, it is usually sufficient to clean it once a week. However, some also advise cleaning the toilet daily.


What does a toilet cleaner cost?

The price range between the different toilet cleaners is not that great. Depending on the quality and the amount contained, the cost point is different.

There are relatively inexpensive toilet cleaner gels, as well as large canisters that last longer and cost more. The range can range from around 5 to 20 euros.

Because you use the toilet cleaner frequently and can clean it thoroughly with it, the prices for toilet cleaners appear reasonable to us.

Where can I buy toilet cleaners?

Toilet cleaners are available in supermarkets, drugstores and building houses, as well as in many online shops. You can usually find them in the detergents section.

According to our research, most of the iron pans are sold in these stores:

  • Aldi
  • Lidl
  • Rosmann
  • Edeka
  • Rewe
  • Aldi
  • real
  • Kaufland
  • OBI
  • DM

You can also buy toilet cleaners online from Amazon or Netto.

What alternatives are there to buying a toilet cleaner?

As an alternative to the weekly toilet cleaner, you can also hang a sink in the toilet. This cleans the toilet with every flush and leaves a pleasant smell permanently.

There are also several home remedies that can be used to replace a purchased toilet cleaner:

The effects of these alternative home remedies are described below:

Home remedies effect
vinegar Table vinegar or vinegar essence has a limescale-removing and disinfecting effect.
Baking powder or baking soda You can remove urine scale with baking soda or baking soda.
citric acid Citric acid cleans your toilet thoroughly and prevents dirt from building up in the first place.
Curd soap If you mix curd soap in your homemade toilet cleaner, it can replace the surfactants in the toilet cleaners you buy.
cola Cola contains acid and can therefore dissolve limescale and other dirt.

Here is a video on how to use the home remedies:

Each of the alternatives has certain advantages that are not to be despised. Nevertheless, a toilet cleaner seems to be superior to the other alternatives in many ways.

Decision: What types of toilet cleaners are there and which one is right for you?

If you want to get yourself a toilet cleaner, there are four variants you can choose between:

  • Toilet cleaner gel
  • Toilet cleaner foam
  • Toilet cleaner tabs

The handling and use of the four different variants of toilet cleaners each have advantages and disadvantages.

Depending on what you prefer and what you want to use the toilet cleaner for, another type is suitable for you. With the following section we would like to make your decision easier.

What distinguishes toilet cleaner gel and what are the advantages and disadvantages?

Toilet cleaner gels are distributed in the toilet with the bottle. The toilet cleaners are available in many different designs.

You have the choice between different amounts and ingredients as well as scents, from the typical lemon scent to tropical to flowers.

So there is something for everyone. Even the more environmentally conscious toilet cleaners often come in the form of gel. The gel toilet cleaners are usually very affordable with 2-5 euros per liter.

  • Different fragrances
  • Choice of quantity
  • Many variants
  • price
  • Must also be distributed
  • Contact with the toilet
  • Unhygienic

When using it, however, you have to distribute the gel extra with the toilet brush, otherwise it will not cover all areas. You will also have to run the bottle under the rim to distribute the gel there too, which makes the bottle unsanitary.

What distinguishes toilet cleaner foam and what are the advantages and disadvantages?

Toilet cleaners that turn into foam only come in powder form. The powder comes in relatively large quantities, which then last a long time.

A small amount of the powder is placed in the toilet for use. When it comes into contact with the water, a foam is created that rises and should reach all parts of the toilet. So there is no manual distribution necessary.

Here we found a video that illustrates the application:

But the foam is a little more expensive than the gel. A bucket with 1kg of powder costs around 15 euros. In addition, there is less choice of scents and modes of action for the foam.

  • Small amount, big effect
  • Foam distributes itself automatically
  • Once bought, you can get by with it for a long time
  • Price point
  • less choice

What distinguishes toilet cleaner tabs and what are the advantages and disadvantages?

With toilet cleaner in the form of tabs, you don't have to worry about the dosage at all. The tabs are individually packaged and intended for a single use.

There is also a small selection of tabs. Depending on what kind of dirt you want to remove, there are specific tabs for this.

  • Light dosage
  • and application
  • Less choice
  • Price point
  • Must dissolve first
  • then be distributed

However, here too the selection is smaller than with the gels. There isn't that much choice of fragrances. In addition, based on the number of applications, the tabs cost a little more than the cheap gels.

The tabs are also a bit more complex in use. They work very well underwater, where they dissolve, but must be spread with the toilet brush so that they also clean the rest of the toilet.

Purchase criteria: You can use these factors to compare and rate toilet cleaners

In the following we will show you which aspects you can use to decide between the multitude of possible toilet cleaners.

The criteria that you can use to compare toilet cleaners include:

  • odor
  • ingredients
  • Exposure time
  • effectiveness

In the following paragraphs we will explain to you what is important when it comes to the individual criteria.


So that your toilet is not only clean and hygienic but also smells great, many toilet cleaners have a fresh scent that they leave in the toilet.

You have the choice between fragrances such as lemon, ocean, lavender and many more. Of course, it all depends on your personal taste.

For very sensitive noses and allergy sufferers, there are of course also fragrance-free toilet cleaners available.



The toilet cleaners use different ingredients to counteract the dirt. There are agents such as lactic acid, chlorine, bleach, hydrochloric acid, and oxygen.

Under no circumstances should you mix such toilet cleaners with each other, as the combination of acid and chlorine creates toxic fumes.

ingredients purpose
Citric acid, lactic acid, hydrochloric acid The acid is mostly used to remove limescale and urine scale.
chlorine Agents containing chlorine, on the other hand, disinfect and bleach particularly well.
oxygen Oxygen bleach cleans, bleaches and disinfects. It breaks down into harmless components and is therefore harmless to the environment.

If you want to protect the environment, make sure to use a toilet cleaner with oxygen, citric acid or lactic acid. These replace the other chemical acids in the product.

There are also toilet cleaners without palm oil, animal testing, completely without chemicals and also without plastic. Particularly environmentally friendly products have the “Euroblower” eco-label.

Exposure time

The specified exposure time is different for each toilet cleaner and it is best to stick to the given time.

In the case of particularly stubborn dirt, it also helps to let the toilet cleaner work longer than the specified time or even overnight.

For example, some tabs have to be left on for several hours, while other cleaners only need to work for 10 minutes. Of course, it depends on what kind of dirt you have to get rid of.

You should therefore pay attention to the different exposure times when buying. If you only have one toilet, you may not be able to wait several hours to use it for the exposure time.


The different cleaners promise different results. Those that contain acid are very good against urine scale or lime scale, while those that contain chlorine are more concerned with bacteria and germs.

Under no circumstances should you mix these together or use them one after the other, as this would create harmful fumes.


If you're buying a biological cleaner with a mild acid and want to remove really thick urine stone, this may not make much sense. But if you only want to maintain a normally used toilet, you can certainly choose the more environmentally friendly option.

Depending on what your use is, you should buy a toilet cleaner that is effective for your case.

Trivia: Facts worth knowing about the subject of toilet cleaners

Can you also use toilet cleaner on metal or marble?

Metal toilets can easily be cleaned with a normal toilet cleaner. However, care should be taken with marble as it is attacked by acids.

Can a toilet cleaner also be used as a weed killer?

Not everyone wants to use chemical weed killers. Maybe you don't have one on hand at the moment. It is best to buy a biological remedy that is effective against weeds and is kind to the environment.

Using home remedies such as vinegar and salt for weeds is prohibited by law. Because the concentration of these agents in the soil becomes very high and can only be broken down poorly. That pollutes the environment too much.

The effect is similar with toilet cleaners. You have certain substances inside that shouldn't get into the ground. Therefore, it is better to buy a suitable remedy or to weed the weeds by hand.

Does toilet cleaner also help against rust?

The following tips for removing rust are sure to sound familiar again. Good home remedies to use for rust are citric acid, vinegar, and cola.

A paste made of baking soda or baking powder mixed with water can also help against rust.

Since these home remedies are very similar to the alternatives to toilet cleaners listed above, you can, conversely, assume that a toilet cleaner can remove rust. If this contains acid, it can kill the rust.

There are also extra rust stain removers to buy in the drugstore.

Are toilet cleaners harmful to the environment?

There are toilet cleaners that claim to be environmentally friendly. But does that mean that all other toilet cleaners are harmful to the environment? And what exactly makes it so bad for the environment?

Toilet cleaners pollute wastewater. They contain chemicals that are not biodegradable. They should therefore not be used excessively and washed down.

Therefore, alternatives to gentler home remedies, as we have already shown you above, or cleaners without chemicals are more environmentally friendly. There is now an ever-increasing range of biological cleaning agents, as the demand is growing steadily.

Unfortunately, a more sustainable variant that does not generate waste, i.e. based on the zero waste principle, is not yet available. The more biological cleaners also come in plastic packaging.
