The application of the foam was carried out as expected, simple, allow to act briefly, and then with a brush and then damp cloth wiped out the dirt. I did not expect to get back the pads totally clean, but it worked. Color changes on the cushion I could not observe, as there were no stains on active foam to the edges, where I applied no cleaner.
The smell of the foam is not intrusive and after a few hours airing smell the upholstery cleaned pleasant.
Unfortunately, the can is almost empty after interior cleaning, but face the very good cleaning performance I rate not the negative. For me the product is very good.
