Abstract: A composition for dissolving and/or inhibiting deposition of scale on a surface of a system comprises an acidic component, a wetting agent, and a corrosion inhibitor. The composition may further comprise water. The acidic component comprises an alkanesulfonic acid, e.g. methanesulfonic acid (MSA). The wetting agent comprises a surfactant. The corrosion inhibitor comprises an amphoteric surfactant. The alkanesulfonic acid is present in an amount of at least about 50 weight percent (wt %), the surfactant is present in an amount of from about 0.1 to about 30 wt %, and the amphoteric surfactant is present in an amount of from about 0.025 to about 20 wt %, each based on 100 wt % of the alkanesulfonic acid, the surfactant, and the amphoteric surfactant combined. A method of dissolving and/or inhibiting deposition of scale on the surface of the system comprises the step of contacting the surface of the system with the composition.
