This time, we were busy cleaning! We received TiefenRein brand dirt erasers to test. The six sponges arrived in plastic packaging, which was inside a shipping bag. The packaging is easy to open or unfold, so that the remaining sponges don’t have to fly around in a half-torn and awkwardly folded plastic package.
There is also an email address on the lid that redirects to support. However, there is no telephone number printed on it.

First impression of the product after opening the packaging
After opening the packaging and evaluating it, we take a closer look at the product’s workmanship. How high-quality are the materials used, and how do the feel and appearance rate?

The TiefenRein dirt erasers arrived fully packaged in a plastic bag supported by an inlay cover providing information about the manufacturer and the product. The back of the cover also contains instructions for using the sponges and safety information. There is also a QR code for subscribing to the newsletter and a reference to the Instagram account.
No odour was noticeable when unpacking; the erasers themselves have a slightly fresh smell.
Visually, the six erasers make a clean impression. They are cut into six uniform cuboids and are bright white. They feel pleasantly soft yet compact, suggesting a high density.
The practical test
The practical test carries the greatest weight. Here, the product must undergo a variety of criteria and examinations by our independent testers. We test the functions promised by the manufacturer of the item under review.

Total | 99,0 |
The product arrived as expected – no nasty surprises. The colour matched the actual product.
The sponges cleaned effectively and thoroughly. As this is a dirt eraser, some material flakes off during cleaning – but this is also described by the manufacturer. However, a larger chunk broke off during cleaning.
We also tested what happens to TiefenRein dirt erasers when we ‘forget’ them in water for a long time. But even after lying in water for 24 hours, the eraser still looks good and can be squeezed out easily. Nothing stands in the way of reuse. Or does it? What does the eraser look like after cleaning? We can reassure you: the sponge can be rinsed off perfectly with water and can be reused immediately afterwards.
