If you feel comfortable doing so, you can prepare a disinfecting solution yourself. First, purchase antiseptic iodine at the pharmacy. Then, mix some fresh lukewarm water with a bit of salt, and add iodine. Depending upon the concentration of the iodine, mix appx. 2 teaspoons of iodine with 4 ounces (100ml) of water. The best way to apply the solution to the affected skin is by using a small sponge. Commercially available products are also available.
