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.

Aurum-Performance®
Microfibre cloth (400GSM)

The microfiber cloths from Aurum-Performance® have been specially developed for professional vehicle care. With a size of 40 × 40 cm and a thickness of 400 GSM, they offer optimum cleaning performance. The lint-free microfiber is velvety, soft and particularly gentle on the paintwork, so that nothing stands in the way of the perfect car wash.

The high-quality polishing cloth is a true all-round wonder and ideal for all surfaces and applications : Car paint, motorcycle, glossy surfaces, cockpit, interior, chrome, piano lacquer and much more. Furthermore, the cloth is very handy with a size of 40 × 40 cm.

The first impression

Packaging and contents

ℹ️ Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The first impression of the microfiber cloths is very good. They are delivered in a classic shipping box that protects the product well. The wipes themselves are packed in a resealable ziplock bag, which makes them easy to store. In addition, shipping paper has been inserted to protect the product so that product protection is fully guaranteed. The outer packaging is made of recyclable paper/cardboard and is therefore sustainable. The package contents are complete and in perfect condition. Six microfiber cloths measuring 40 cm x 40 cm are supplied. The instructions for use are clearly written in German and contain care instructions and information on the material composition.

As part of the practical test, the microfiber cloths from Aurum-Performance® were tested for their performance and quality. The results show that the cloths fully live up to the manufacturer’s advertising promises.
The microfiber cloths proved to be extremely effective in removing dirt, dust, fingerprints and other contaminants from various surfaces such as car paint, motorcycle, glossy surfaces, cockpit, interior and household. Both interior and exterior mirrors could be optimally cleaned without leaving streaks or smears.
The scratch-resistant properties of the cloths, which effectively prevent damage to the cleaned surfaces, are particularly positive. Even after repeated washing in the washing machine at up to 40 °C, Aurum-Performance® microfiber cloths retain their quality and cleaning performance.
Overall, the microfiber cloths are an excellent choice for cleaning various surfaces. They offer outstanding cleaning performance, leave no streaks or smears and can therefore be recommended without reservation for the care of car paintwork, motorcycles, glossy surfaces, cockpits, interiors and in the home.
In conclusion, Aurum-Performance® microfiber cloths are convincing in terms of effectiveness, quality and user-friendliness, making them a worthwhile investment for all cleaning needs.

Price/performance ratio

and ratings from consumers

ℹ️ Finally, we examine how the product compares to the competition. Can it keep up with the competition in terms of price and quality? Would we generally recommend buying it? We also look at the consumer reviews and check whether the critical and positive reviews are actually justified.

CriterionRemarkScore achieved*
Price / performance ratioVery good performance in the mid-price segment90 points
Rating cut4.8 out of 5.0 on Amazon90 points
Total90 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.8 stars. Positive customer reviews particularly praise the streak-free cleaning and the high suction power of the cloths. However, individual cases complain that the product is not absorbent enough. In our practical test, we were able to confirm that the cleaning performance of the cloths is very good. We found the wipes’ suction power to be very high.

Prices of up to €35 are charged on the Internet for equivalent products. Very inexpensive products are available for as little as € 8 . The microfiber cloths from Aurum-Performance® are therefore currently in the middle price segment with a price of € 17.95 for six pieces. For the quality and performance received, the price-performance ratio is very good.
