The stripping of forming and support systems is the direct opposite of how it was placed together.  Keep in mind that fresh concrete is still quite fragile and care should be exercised in disassembly.  In many instances, the materials can be cleaned and used again for another project.  Under no circumstances allow organic material to remain as the inevitable decomposition will leave voids that can cause cracking or caving.  Any coping or other metal edging will undoubtedly have concrete residue, which along with the remains of the pan head bolts from the coping supports, will have to be removed.  Remove the excess weld and pan head bolts with an angle grinder fixed with a steel grinding wheel.  Do not attempt to hammer the bolts off as the impact to the coping will travel through the rebar and may irreparably damage the concrete.  Concrete residue can be removed with a die grinder fitted with a wire wheel or the residue can be removed more slowly with a wire brush.
