@livelifefull18: Here is how we use super 10 on car engines. Use Super 10 (1:3 mixture) Spray on while engine is warm and allow to stand for 15 minutes , then spray Super 10 mixture again. Agitate with brush. Rinse with a garden hose. Repeat of necessary. https://shopneolife.com/RAEDAAB #neolifestories #proudNeolifer #CarMaintenance #cleanengine #super10
