The product is Greek and of excellent quality. It has a rich quantity of wax. You caress the car's hood and enjoy it. I have been using it for 3 years and it cannot be compared even with much more expensive shampoos. Its price is amazing and the result is even better. I wash it by hand and sometimes with a pressure washer.

Although it is a cheap product, it does its job well. It can be used with a sprayer, but I use it directly on the car body as a pre-wash to remove the "thick" dirt, and then I spray it again and continue with a bucket and sponge.
Certainly, you can't compare it to more expensive brands because it requires quite a few hands, but for €15, it does the job just fine!
Note that if the car is in the sun, it is good to rinse it quickly as it leaves marks. It doesn't show as much on mine because it is white.

I bought it hesitantly because there are many well-known brands in the market and I didn't know if I could trust this particular "local" solution. It turned out to be a decent shampoo that cleans quite well.
It contains a lot of wax, which means you need to be careful with the dosage when washing your car. Let me explain: my Civic EJ6 (coupe) has dimensions of 4.50x1.70x1.37, and I made the mistake of washing it twice in a row (2 buckets = 2 caps of liquid), just because I wasn't sure about the result afterwards. It resulted in a terrible residue, as shortly after drying, I noticed a haze from the wax on the hood and the sky, and I had to lightly buff it with a microfiber cloth. Also, due to this mistake, the windows became hazy from the wax (I noticed it the next day when the car was in the sun), and I had to struggle to clean them with Ajax.
So, anyone planning to buy it and if their vehicle is the same size as mine, should calculate that 1 cap in a full bucket does a good job, but they should remember not to clean the windows with it, or if they do, clean the windows with glass cleaner and paper after drying to prevent them from fogging up later.
