STARKL
Carbon microfibre cloth

Starkl microfiber cloths have been specially developed for cleaning car windscreens, windows, mirrors and displays. With a size of 40 x 40 cm and a thickness of 400 GSM, they offer optimum cleaning performance. The special feature of these cloths is the woven-in carbon fiber, which ensures deep nano-cleaning and effortlessly removes even stubborn dirt. They are also 100% lint-free and can be cleaned in the washing machine at up to 95°C. The absorbency of the cloths and the streak-free result should also be emphasized.

Advantages

✅ Outstanding cleaning performance
✅ Streak and smear-free result

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?

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. Four 40cm x 40cm microfiber cloths and a laundry net are supplied. The instructions for use are clearly written in German and contain care instructions and information on the material composition.

The practical test has shown that Starkl’s microfiber cloths keep their advertising promises . They are extremely effective at removing dirt, dust, fingerprints and other soiling from car windows. The interior and exterior mirrors were also cleaned perfectly . The wipes leave no streaks or smears on the car windows after cleaning and are scratch-resistant, preventing damage to the window surface. Cleaning the cloths is very easy, they can be washed in the washing machine at up to 95°C and dried in the dryer at 1000 revolutions per minute. The cloths retain their quality even after repeated washing. Starkl microfiber cloths are a good choice for cleaning car windscreens, windows, mirrors and displays. They offer excellent cleaning performance, leave no streaks or smears and are therefore recommended.

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 good100 points
Rating cut4.5 out of 5.0 on Amazon75 points
Total88 points
Weighting: 15%
*The maximum score is 100 points

On the Amazon platform, consumers rate the product with an average of 4.5 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 does not clean streak-free. In our practical test, we were able to confirm that the cleaning performance of the cloths is very good. We cannot confirm the streaks left behind.

Prices of up to €25.99 for four pieces are charged on the Internet for equivalent products. Very inexpensive products are available for as little as €12.98 for four pieces. The STARKL microfiber cloths are therefore currently in the lower price segment with a price of € 12.99 for four pieces. For the quality and performance received, the price-performance ratio is very good.
