Another amazing Sonax product... This upholstery cleaner works just as advertised. It softens the soiled spots on the carpet and then wipes up effortlessly. I used 2 black all purpose towels for use. 1 slightly dampened and 1 dry towel. The thing I noticed right away was how concentrated the product is. It took 3 sprays to remove a dried syrup like stain on the carpet. Like I stated, it softened up the dried product and lifted it up and removed it. with very little agitation. The product also is stated to be an odor eliminator. And I found this to be true. It leaves an amazing citrus like scent that IMO is amazing. For comparison purposes the products I use on carpet are 303 carpet spot remover, Ultima interior shampoo and Blackfire interior cleaner. Those product have worked well for me. BUT this Sonax product is easily more effective. It works a LOT faster (basically no dwell time), with less product (more concentrated), cleans up easier and to top it off is an odor eliminator that smells better than those other 2 products listed. I was so impressed with this product that I just ran into the house to write this review before I forgot the specific details of what I though about it. All while in the middle of a detail. I am that impressed. I would highly suggest that everyone who see's this review gives it a try. If you use the products that I have listed I am very confident that you will feel similar how I do about this.
