Ultra-Magnum Is a non corrosive heavy duty alkaline cleaner with built in buffers for additional safety. Formulated to rapidly dissolve carbon, bugs, and oil from the exteriors of aircraft. Ultra-Magnum has been engineered to clean planes that have seen better days cosmetically. Such aircraft typically have dead paint that absorbs carbon, bugs, and oil, staining the paint. This requires an aggressive cleaner to deep clean weathered aircraft surfaces. Recommended dilutions 5 to 1 or 10 to 1.
