There is a common perception amongst car owners about using isopropyl alcohol for removing ceramic coating from a car. Using isopropyl alcohol for removing ceramic coating is not a feasible option as it is not a traditional remover. It is more like a polishing agent that is used before applying a coating to the car paint. Besides, it is also considered harmful for any kind of pre-painting job as it may leave behind unclear or impure residues that might not go well with the paint or coating that you apply soon after. Thus, it is suggested to avoid isopropyl alcohol for any kind of ceramic coating removal procedure.
