Did you know that most surface cleaners are a mix of 5% solution and a whopping 95% water? That's a whole lot of bottle you're buying every time for such a small amount of concentrate. Replenish recognizes that ratio can be made the most of with their new bottle design. The large, top half is designed to be reused; The bottom portion carries enough cleanser for four h20-from-the-tap refills, and buying a replacement requires a quick trip to the online store (with free shipping, no less!). We have it on excellent authority from a decidedly tidy and ever-clean colleague that the stuff works wonders.
