The usual: Painless antiseptic for small cuts, blisters, abrasions
The unusual: A cheap teeth whitener. Swish the 3 percent solution without dilution for a minute or so before you brush. Think of it as a pre-rinse. Another unexpected use: If your dog is like mine and eats things he shouldn't, keep it on hand to induce pet vomiting (but talk to your vet first).
