About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

The first impression

The packaging and labelling

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. Of course, adequate protection of the product must also be ensured.

Contents of the shipping carton

The upholstery cleaner from TREUEFIX was delivered in a typical shipping box. The shipping box was compact and the product had little room to move. Therefore, the remaining space in the shipping box was filled with recycled paper filling material. The product packaging was undamaged and in perfect condition. Both the shipping carton and the product packaging were easy to open without tools. The bottle cap is also wrapped in a foam film. This prevents leakage and protects the cap. The packaging of the upholstery cleaner is recyclable apart from the film. Overall, the cleaner makes a good impression.

After unpacking

Package contents and instructions

ℹ️ Most people’s first impression after unpacking is immediately memorable. Are the contents of the pack complete and does the manufacturer make it as easy as possible for me to use the product straight away?

Tapered opening

The upholstery cleaner is supplied in a transparent 1-litre bottle. This is particularly advantageous as the level of the cleaner can be easily read. The opening of the cap is tapered so that more precise dosing is possible. The cleaner itself has a white-transparent colour and smells pleasantly fresh. The clean finish and the cap make a very good impression. The upholstery cleaner from TREUEFIX is free from microplastics and is produced without animal testing. The concentrate is compatible with all commercially available washing vacuum cleaners and wet vacuum cleaners and can also be used by hand with a sponge/brush. The hazard warning “Keep out of the reach of children” is attached. The cleaning agent must be kept out of the reach of children.

This is what our practical test showed

After mixing the concentrate with water in the specified ratio, cleaning can begin immediately . It is important to observe the prescribed dosage. We discovered a stubborn stain on our carpet and carried out the test on it. The mixture was applied to the area to be cleaned and worked in with circular movements. After just a short scrubbing, the stain was easily removed. Finally, the cleaned area was rubbed with cold water. The stain was easily removed thanks to the cleaner. The cleaning concentrate is also suitable for cleaning with a wet or washing vacuum cleaner.
Simply repeat the process for heavy soiling. The cleaner also exudes a wonderfully fresh fragrance.
The carpet feels pleasantly fresh and looks like new.
Before use, the cleaning concentrate should be tested for compatibility in an inconspicuous area.
The concentrate can be stored at a temperature between 5° and 25°C.
