Disclosed is a method for removing magnetic particles from Fischer-Tropsch synthetic crude oil, comprising: a solid-liquid separation process in which solid components are separated from synthetic crude oil formed by a Fischer-Tropsch synthesis reaction; and a magnetic separation process in which magnetic particles present in the synthetic crude oil that has undergone the solid-liquid separation process are trapped, and the magnetic particles are separated from the synthetic crude oil. The magnetic separation process is conducted using a high gradient magnetic separator having a cleaning solution introduction line that introduces a cleaning solution to intermittently wash the trapped magnetic particles, and a cleaning solution discharging line that discharges the cleaning solution after the solution is used to wash the magnetic particles.
