I just bought a k-2006c from Amazon. When I opened it one of the vials of DPD powder had opened and exploded all over the inside. When I processed my replacement they told me it was back ordered for 8 weeks. I am willing to lose the cost of the powder, but is there any risk in cleaning off the powder and using the kit, or can it taint results and such? Does the powder itself pose a risk, the msds didn't seem like it was all that bad.
