It did what it promises, right away.
It cleaned surfaces on doors that were in a terrible state, blackened. So what do you do? Simply spray the foam, scrub with the brush from the lid, and finish with a microfiber cloth soaked in warm water! All this for under 5€!! I highly recommend it.

In beige fabric car upholstery, moderately dirty from the weather, it was as if I didn't use almost any cleaning product, despite following the instructions to the letter.

I bought it based on the reviews here, I didn't try any other to compare. It's a children's seat, very dirty, so much so that I thought the fabric had faded from the sun and burned. I followed the instructions and it looked like new, exactly in the original color. Impressive. Now, as for the chemicals, I didn't pay attention to the point where the dirt had reached...

Value for money!!! It does what it promises!!! It cleaned the car seats from stains caused by sea salt and sweat.

Guys, flawless!!! Look at it before and after! I think the photos speak for themselves. I cleaned it with a soft microfiber cloth, so as not to "injure" the surface of the fabric seats.
Awesome!

Excellent and easy to apply! It requires attention to make sure the foam goes everywhere because the difference is noticeable where it hasn't reached. After brushing, I immediately use a towel to make sure it reaches even the most difficult areas.
