Aluspray Aerosol Bandage aids in protecting wounds against bacterial contamination. Aluspray does not contain sulfa or antibiotics. Aluspray contains a proprietary carrier that aids the active wound protective formula to adhere to the skin and cannot be washed off with hot or cold water. Aluspray can be washed off with soapy water to inspect wound. The spray allows the wound to oxygenate (breathe) to aid in wound healing. Can be applied without disturbing sensitive wound tissue, or may also be applied over ointments used to aid in wound healing. Brand Varies.
