General information

We took a close look at and tested the product in a practical test. In the following, we take a closer look at the features and impressions. From the packaging, materials and quality to the range of functions and handling, the product is subjected to our test procedure.
To give you a quick overview, we work with a points system. The maximum achievable score per area is 100 points. The final overall score is calculated from the average of all tested features, taking into account the respective weighting.

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 product was delivered in a typical shipping carton, which was undamaged on arrival and could be opened without any problems. The carton contained a 1 liter plastic bottle and a 500 ml plastic bottle. The carton as product protection proved to be stable and adequately protected the product during transportation. However, no original packaging was available at the time of testing, so no statement can be made in this regard. Instructions for use, information and ingredients are noted on the bottle label, but no additional instructions for use are enclosed.

The upholstery cleaner before the test

The KLARBERG upholstery cleaner concentrate is visually in very good condition. No damage, corners or edges were found during processing. The two plastic bottles containing 1 liter and 500 ml are stable and practical. With regard to the sustainability of the product, it should be mentioned that it is a highly concentrated concentrate that contains less than 15% phosphates.

This is what our practical test showed

Does the manufacturer keep its advertising promises?

ℹ️ Our practical test has the highest relevance and therefore weighting. Here, the product has to undergo a wide range of criteria and tests. We check the functions and product promises of the test article.

*The maximum score is 100 points

Our practical test has shown that the cleaning effect of KLARBERG Upholstery Cleaner is very good and that it is easy to use. The cleaner can also be used undiluted for heavy soiling. However, it is advisable to test the material compatibility on a non-visible area beforehand. It can be used with a spray bottle, which must be purchased separately, or with a bucket of warm water and absorbent cloths, pads or sponges.
In our own practical test, we were able to confirm the positive aspects of the KLARBERG upholstery cleaner. It proved to be very effective for cleaning various textile surfaces in the home and car. The cleaning power of the product was satisfactory overall and largely fulfilled the properties promised by the manufacturer.
The product is a good option for those who want to thoroughly clean their textiles.

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 ratioAppropriate80 points
Rating cut4.3 out of 5.0 on Amazon65 points
Total73 points
Weighting: 15%
*The maximum score is 100 points

The KLARBERG upholstery cleaner has received an average rating of 4.3 stars on the Amazon platform. Customers particularly praise the cleaning agent’s economical and easy-to-measure formula. It was positively emphasized that the product removes dirt and stains effortlessly and leaves a pleasant scent. The gentle yet thorough cleaning is also mentioned positively, as stains on upholstery, couches and chairs were effectively removed.
However, some customers mention that they needed a considerable amount of the detergent to clean larger areas and therefore had to purchase additional quantities. In addition, when using a low mixing ratio on long-pile carpets, an unpleasant greasy film was criticized, which made subsequent cleaning necessary.
In our own practical test, we were able to confirm the positive aspects of the upholstery cleaning agent.

Prices of up to €35.80/l are charged on the Internet for equivalent products. Very inexpensive products are available from as little as €11.90/l. The KLARBERG upholstery cleaner is therefore currently in the middle price segment with a price of 17.99 €/l. For the quality and performance received, the price-performance ratio is reasonable.
