1. A method of recycling carbon fibers comprising:
preparing a carbon fiber reinforced plastic molded product containing a carbon fiber reinforced plastic containing a carbon fiber and a resin;
performing a process of at least one of a heating process or an ultraviolet irradiation process on the carbon fiber reinforced plastic molded product; and
after the process, removing the resin after the process from the carbon fiber by applying a first liquid to at least the carbon fiber of the carbon fiber reinforced plastic molded product.
