Decision: What types of green soap are there and which one is right for you?

Basically, a distinction is made between two types of green soap:

  • green soap for indoors
  • green soap for outdoor use

These different variants have special properties, which come with individual advantages and disadvantages.

For certain circumstances, different types of green soap are better suited. The following sections will help you find the right one.

For this purpose, we will introduce you to the types just mentioned and describe their advantages and disadvantages.

What are the characteristics of indoor green soap and what are its advantages and disadvantages?

For indoor use, green soap is a real all-rounder. It can dissolve and absorb dirt and oily stains. You can use it especially for furniture, laundry, dishes, windows, floors or even carpets.

  • Very versatile
  • Environmentally friendly and biodegradable
  • Cares for wooden floors
  • Not suitable for laminate and linoleum floors
  • Cleaning with solid soap more difficult

For indoor use, it is also recommended to add some liquid green soap to a bucket of water. This is an excellent way to clean parquet and wooden floors, which are also cared for by the regreasing effect.

However, you must use a different cleaning agent for laminate and linoleum floors, as green soap can damage them.

What are the characteristics of green soap for outdoor use and what are its advantages and disadvantages?

You can use green soap in many different ways outdoors. Above all, green soap is suitable for loosening and removing dirt from furniture and green coverings on the terrace.

  • Very versatile
  • Environmentally friendly and biodegradable
  • Fights aphids
  • Not suitable for all coverings
  • Must first be dissolved

You can also use it to clean wooden and stone floors. These can be made shiny by cleaning with the green soap.

If you have an infestation of aphids, you can also use the green soap to combat them.

Buying criteria: You can compare and evaluate green soap based on these factors

In the following, we will show you which factors you should pay attention to and help you decide between the different green soaps.

The criteria you can use to compare green soap include:

  • Ingredients
  • Area of application
  • Packaging
  • Processing quality
  • Solid or liquid

In the following sections, we will explain in more detail what is important in each factor.


In general, the ingredients of green soaps are very similar. They are all based on a potash lye with various oils. These are mostly vegetable fats such as hemp, linseed or rapeseed oil.

In addition, these soaps are mostly all-natural and contain no fragrances. Nevertheless, you should keep an eye on them, as some products do contain fragrances. They also have a neutral pH value of 8.5 - 9.5, which makes them particularly suitable for allergy sufferers.

Area of application

Before buying green soap, you should think about what you want to use it for. Do you only need it for smaller areas, such as dishes, or do you want to use it to clean larger areas and floors.

You can then measure how much green soap you need accordingly.

Liquid green soap is also better for larger areas, as you can simply mix it into a bucket of water and use it to clean dirt. Also, larger quantities of green soap are usually cheaper.


Green soap is an all-natural product that is biodegradable and therefore very environmentally friendly. In addition, since there are no additives, this soap is also suitable for allergy sufferers.

To promote this sustainability and purity, it is important to pay attention to the packaging. With liquid green soap, this is a little more difficult, as most manufacturers sell it in plastic packaging.

However, especially with solid soap, you can make sure that it is packaged in paper and not plastic.

Processing quality

The quality of workmanship is also an important criterion when buying green soap. The most important thing is that the ingredients are of high quality and well processed.

If this is the case, it can prolong the shelf life of the soap because it is more stable. However, high-quality products are of course somewhat more expensive.

Solid or liquid

The decision between solid or liquid soap is entirely up to you, depending on what you like better. Both variants have the same intensive cleansing effect.

However, solid soap does not dissolve as quickly in water. If you use warm water, this is also a little easier. Liquid green soap, on the other hand, dissolves very quickly in water.

Facts about green soap

How do I dispose of green soap?

Basically, disposing of green soap is very easy because it is biodegradable. Biodegradable means that substances can be broken down into their elementary components by microorganisms. These are substances such as oxygen, carbon dioxide, hydrogen and other minerals.

This means that you can safely pour the cleaning water with the soap into the lawn in the garden, for example, to dispose of it.

In addition, with solid soap you can easily combine old residues and new products. All you have to do is wet the bars of soap, press them together and they will dry firmly together.

Can I make green soap myself?

In general, you can make your own green soap. However, this is a rather difficult and quite dangerous process. Therefore, you should make sure that there are no children or animals around during the production and that you carry out each step carefully.

To make your own green soap, you need a potash lye, fats and oils. The lye is very corrosive, so you have to be very careful with it. To make green soap, you now need:

  • Melt the selected fats or oils in a pot. Then you have to make the potash lye and let it cool down.
  • Pour these two products together and mix them with a mixing rod to make a soap glue.
  • Finally, put the soap glue into a container and let it rest for 24 hours. After that you have to let the soap rest for another 3-4 weeks.

It is also important to always wear protective goggles and rubber gloves.

How do I clean with green soap?

Basically, you use green soap just like other soaps. You just mix the soap with a little water. Liquid green soap dissolves by itself, whereas you have to help a little with solid soap.

With this mixture, you can simply wipe and clean the desired area. Another advantage is that no wiping is necessary, as this soap does not leave streaks. However, when treating green coatings, it is recommended to spray the terrace with water to loosen these coatings somewhat.

In case of heavy soiling, you can also use the green soap pure.
