I've used this brush on Alcantara interiors, works just great. In addition, its shape makes it easier to reach hard-to-reach curved corners. I only gave it 4 stars because the bristles could have been a bit softer and shorter to allow for better and gentler cleaning, I feel like I could get the same. Foam block result, but I think a brush will do a better job of removing debris from seams and seams. I used Sonax upholstery and Alcantara foam cleaner. Great stuff too.
