Review on Nikwax Softshell Cleaning and Waterproofing Duo-Pack, 20 oz. / 600ml by Mike Hernandez

Used both and followed directions, only difference was I packed 1 Columbia soft shell winter jacket and 1 Columbia wind/rain jacket as one load and filled them to a medium water level as the jacket was thick and absorbed most of the water. I then used half a bottle of Tech Wash on Load and then a load of Softshell after the Tech Wash was complete. While both jackets were in and the washing machine was filling up a second time, I also made sure to rinse the softshell material to fully mix it with the water (and this was starting to make my hand water-repellent, so next time grab a broomstick). or something like that, the hand wash afterword was a nightmare as the thing wouldn't wash with normal soap but at least I knew it would work!) In short both jackets looked and smelled like new and beaded. tighten, don't soak. I will buy again. The only caveat is that half a bottle of Tech Wash and a full bottle of Softshell were used on these two jackets. They were both 2x waist length so plan accordingly. A bottle won't get you far. I definitely couldn't stuff into the third point.
