Provide are methods and systems for inhibiting corrosion of a metal surface. An example method comprises providing a treatment fluid comprising an aqueous carrier fluid and a polyhydroxyetheramine corrosion inhibitor; contacting the metal surface with the treatment fluid; and contacting the metal surface with a mineral acid. Another example method comprises providing a treatment fluid comprising an aqueous carrier fluid, a non-polyhydroxyetheramine corrosion inhibitor, and a polyhydroxyetheramine corrosion inhibitor intensifier; contacting the metal surface with the treatment fluid; and contacting the metal surface with an organic acid. An example system comprises a treatment fluid comprising a polyhydroxyetheramine, an acid, and an aqueous carrier fluid; mixing equipment capable of containing the treatment fluid; pumping equipment capable of pumping the treatment fluid into a wellbore; and the metal surface.
