Abstract: A de-icing assembly is used for unblocking a trailer brake line. The trailer brake line includes a receiving end that is connected to a truck end of a truck brake line. The de-icing assembly includes a housing including an interior space for storing an alcohol fluid. The housing also defines a top surface and a bottom surface. An inlet extends through the top surface. The inlet is removably connectable to the truck end of the truck brake line. The de-icing outlet also includes an outlet that is removably connectable to the receiving end of the trailer brake line. The outlet includes a fluid tube extending to a distal end disposed adjacent the bottom surface of the housing such that pressurized air received in the housing from the inlet forces the alcohol fluid stored in the housing out the outlet and into the trailer brake line to unblock the trailer brake line.
