I was only able to use this cleanser once. I tightly capped it but a couple days later, it was hardened like concrete! I tried swishing some hot water around in it, but the crystals wouldn't soften up. I could only use it a second time if I used a butter knife to chip and chisel some pieces out, and these didn't break down and lather at all. So many nice reviews of this product, maybe mine is part of a bad batch?
