Inspection After Removal

WARNING: To avoid the risk of injury to eyes and skin, when using caustic solutions solvents, acids, or alkaline materials, follow the manufacturer's recommendations for use and wear appropriate eye protection and protective clothing. Some of these materials are also flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Avoid spilling onto a hot exhaust manifold which can cause a fire.
