The best car cleaner I have bought so far. I have tried several products from top detailing brands, but this one is a Swiss army knife. Work it with a brush to create a good foam and wipe after a while with a clean cloth. The result is excellent. Note that this is the 3rd bottle I have purchased...

It really does an excellent job. I used it as a home detailing solution for a car with a leather, light-colored interior that had cigarette smoke residue. For better results, I applied it with an appropriate brush. The interior returned to its original color, as if after a professional biological cleaning. In some areas, additional applications were needed for a perfect result, so a little patience is required – for this reason, even though it says it doesn't need rinsing, I was a bit cautious and wiped it with a wet cloth and leather conditioner after it dried. If you wipe with a clean cloth and repeat, the result is faster. With one bottle I fully cleaned a large SUV – interior, plastic parts, seatbelts (without dilution). It is not completely odorless, it has a slight smell reminiscent of antiseptic, but nothing bothersome. It's a pity I didn't keep photos of the front seats, where the difference was impressive.

Guys, the smell, like other things, is subjective perceptions. Everyone smells it differently. I didn't like it at all. Very bad. It doesn't smell new at all!! It smells more like low-quality plastic than the smell of a new vehicle. What can I say... just a waste of money! It's better to clean your car often or even better to take it for a biological cleaning, instead of this disgust!

Honestly, I didn't expect such results from a product, especially with so little effort! You spray it, work it in a bit with a detailing brush, and simply wipe it off with a microfiber cloth. Unfortunately, I don't have a before/after picture, but in general, in the photo, it seems like I'm obsessed with the detail, especially on the interior of the car. Not only would I buy it again, but I'm also considering getting more to have in stock.

The product can be diluted 1:10 and become very economical! I use it as is and it easily removes stains from the interior! Spray it on a brush, scrub, and then wipe with a soft cloth! It has no scent, it is colorless, and it does not damage leather surfaces! It is considered and is one of the best! Buy it with closed eyes!

I bought the product with the intention of using it on chairs and sofas with faux leather fabric. I thought that the material would match the materials inside the car. Until now, I had never cleaned/maintained them (I have had them for over 10 years with good use). Also, I have no experience with specialized car products.
I cleaned with Chemical Guys Nonsense in a ratio of 5:1 and with a very soft brush on both the seams and the large surfaces. It created a little foam and dried relatively quickly, even though it was winter and I was indoors. For this reason, I used it in sections. It seemed to remove shine and dust and leave a uniform matte result. I dried it with a clean microfiber cloth without rinsing and continued with Chemical Guys VRP. Overall, I was satisfied and I consider it economical due to its dilution capability.

It removes all the dirt and it is also economical since it is 1/20, meaning you have approximately 10 liters of product. I approve it for both pro detailers and anyone who wants to have a clean car. However, I would recommend it especially to professionals of Koch Chemie GS
