Methods of uniformly removing coatings from metallic substrates, such as tools and dies, without damaging the surface of the underlying substrate are provided. The processes are optimized for steel substrates with metallic carbide or nitride coatings. The methods encompass aqueous electrochemical removal using stirred, low temperature, basic electrolytes. Following removal of an old coating, a new coating may be applied, allowing recycle and reuse of the underlying metal substrate. The ability to recoat and reuse tools represents a significant cost savings.
