After trimming my dogs' nails, I accidentally left the jar of styptic powder open overnight. During that time, it absorbed some water from the atmosphere so that the top layer is slightly damp and clumps together. I'm concerned that having some water in the styptic would allow bacteria to grow.
Is this slightly damp layer still safe to use on my dogs? If not, what about the powder that was underneath the surface layer that is still dry? Can I do anything to dry it out, like heating it gently for a time?
