Abstract
Heat exchangers and other equipment whose surfaces have become fouled with sludge deposits that comprise a cuprous halide are cleaned by contacting the fouled surfaces of the equipment with a cleaning solution that contains 5% to 35% by weight of an alkyl aluminum halide in a hydrocarbon solution and then washing the surfaces with a hydrocarbon solvent to remove loosened sludge and residual cleaning solution.
