If it fizzes, peroxide is good, even if degraded a bit. It eventually turns into water.
Thanks jjotto
I just looked in the linen closet and we have 5 big bottles of it. I remember now we used it as part of the bath when my Yorkie got too close to a skunk. That was at the other house, looks like he is behaving himself better here. Or we don’t have those little critters
One Summer he entangled with skunks so often that the hydrogen peroxide was turning his fur red. His vet said that she never saw her like that on a Yorkie before. So we had to admit what he had been up to.
