Very good, it needs a good scrubbing for about 5 minutes and use a generous amount for it to work!!!
It also works on salt from the beach!!

I wasn't thrilled with its application and how much it cleans the upholstery. The cleaning is purely superficial and it also leaves a stain around the area of application

Very effective. I cleaned the seats in a car we bought used and it had stains from dirt, as well as the fabric on the side of the door. For its very low price, it's worth it with closed eyes. I will definitely buy it again.

It's worth its money, it's honest. It cleaned the car seats of the work oil and dirt they had on them.

I bought it because I trust K2 products and I consider them reliable. However, this particular one disappointed me. I used it to clean the car's carpet, which was very dirty, and personally I felt that it got worse. I spread it first and then rubbed it with a soft brush, but unfortunately the result was disappointing!

I cleaned the carpet where coffee had spilled. It cleaned perfectly, without leaving any marks or discoloration. I used a brush on a drill. Overkill for such a stain. With a hard brush, it's perfect. Economical and in sufficient quantity.

Simply perfect, it had a stain for 2 years and it easily came off the second time. From the first time, it had removed 80 percent

Very good upholstery cleaner, I made my car organic vacuum cleaner bissel and cleaned all the upholstery, the smell I saw in the water tank was unbelievable, I didn't expect it to do such a good job! And at an excellent price!

It is quite good at removing simple stains. For difficult cases, it does not work or will require a lot of product and effort. However, it is particularly cheap, so you cannot have excessive expectations. In fact, it does not fall behind compared to some more expensive products from major companies in the industry.

The product does what it promises with relative ease (personally, I spray it on a microfiber cloth and then clean the surface I want) it leaves no residue on surfaces and I would say it is odorless.

It is ideal to avoid cleaning surfaces that are exposed to the sun for a long time.

It is recommended for purchase due to its cleaning power and obviously its price.

The foam of the K2 is mediocre, but it is significantly better and it also gives you a hard time until the seat is completely filled with foam, making it soapy and difficult to clean easily

For the money, it does a good job. I cleaned the back seats and used half a bottle. I vacuumed, sprayed, and scrubbed with a brush

I have been using it for a long time in rental cars. Simple to use, it cleans the fabrics on the seats quite well. It is not for professional use, but it is good enough and honest.

I thought with these reviews it would be excellent, but it's not. The Lindl one I have tried did a better job and had a pleasant scent as well. You can see enough of it, but it doesn't spray well and it takes a lot to achieve good coverage. The brush of the K2 that I use is excellent.

The main advantage is its very low price, while at the same time it does a very good job. It easily and quickly removes stains and dust from the seats with a little rubbing and then wiping with a dry microfiber cloth. The bottle is very convenient with various spraying methods that help you not waste too much material for a simple refreshment of the seats. I would definitely buy it again.

Very good product, just like everything else I have purchased from K2, which has created amazing products at very good value for money prices! Excellent. I highly recommend it.

Very good, it easily removes typical stains. It also has a wonderful scent. I doubt its effectiveness on tougher stains like oil stains. But for this price, it seems very good to me.

Maybe it is more effective than the equivalent Auto-glym that I have tried. Very satisfied.

It is one of the best cleaners. It had some stains on the seats from the cat... It didn't come out with any method, but with a little scrubbing they became spotless

It was tested on light stains on the seats, it removed them all with a brush and it smells pleasant. It has not been tested on tough stains yet!! For now, it seems like a good and honest choice in terms of price and performance!!
