I have tried many other products and none have been as good as this one at eliminating the chlorine smell in my suit.
I've tried all the suit rinses there are, as well as just rinsing in water, and I've found that the Malibu C Crystals are really the best. It's best to use them right away, as in the place where you swim, rather than waiting until you get home and your suit is half dry. If you use it religiously it will definitely extend the life of your suit.
I have been using this product for over a year now and it is fantastic. I teach aquatics classes and am in the water daily. I use it for both my swimsuits and wet suit jacket and have found it to prolong the life of both. I would highly recommend it.
