Among other things, corrosion-inhibiting additives that comprise certain surfactants, and associated treatment fluids and methods of use are provided. In one embodiment, the methods comprise: providing a treatment fluid that comprises a base fluid, an alpha,beta-unsaturated aldehyde, a sulfur-containing compound, and at least one nitrogen-containing surfactant that is anionic, nonionic, amphoteric, or zwitterionic; and introducing the treatment fluid into a subterranean formation. In another embodiment, the methods comprise: providing a corrosion-inhibiting additive that comprises an alpha,beta-unsaturated aldehyde, a sulfur-containing compound, and at least one nitrogen-containing surfactant that is anionic, nonionic, amphoteric, or zwitterionic; contacting a surface with the corrosion-inhibiting additive; and allowing the corrosion-inhibiting additive to interact with the surface, whereby corrosion of the surface is at least partially inhibited or a portion of an undesirable substance on the surface is removed.
