Abstract: Exemplary methods of removing lithium-containing deposits may include heating a surface of a lithium-containing deposit. The surface may include oxygen or nitrogen, and the lithium-containing deposit may be disposed on a surface of a processing chamber. The methods may include contacting the surface of the lithium-containing deposit with a hydrogen-containing precursor. The contacting may hydrogenate the surface of the lithium-containing deposit. The methods may include contacting the lithium-containing deposit with a nitrogen-containing precursor to form volatile byproducts. The methods may include exhausting the volatile byproducts of the lithium-containing deposit from the processing chamber.
