A gas turbine engine component having a thermal barrier coating is immersed in an inorganic hydroxide bath having a high concentration of alkali or alkaline earth hydroxide with the bath at ambient (atmospheric) pressure and elevated temperature for a time sufficient to effect rapid detachment of the thermal barrier coating for removal from the substrate. The component then optionally can be immersed in a water bath to remove any remaining thermal barrier coating. The thermal barrier coating is removed without detectable damage to the substrate or any bondcoat present thereon.
