I am an interior designer and recommend that my clients protect all their new furniture upon delivery. After using Fiber seal, Guardian Seal, and scotchgard for over 20 years, I was really enthusiastic when I heard about the first "green" fabric and carpet protectant without the harmful chemicals. Using the recommended dilution, I experienced water mark stains on a synthetic blend/linen fabric. I had good results when used on 100% linen placemats. I had uneven drying on a napped chenille fabric which required lots of brushing and drying with a hair dryer to raise the nap again. I am going to experiment using part alcohol instead of all water and see if that works better to avoid water marks caused by uneven drying. Since there are no detailed user instructions for various textiles, I will continue experimenting and hopefully can increase my review to 5 stars when I figure out the best way to apply and perhaps customize the ratio of dilution.
