Spray the outside and inlets of the intercooler with degreaser to prepare any gunk or debris for removal. After that, you can use acetone or kerosene to rinse out the intercooler. Place in a container and pour the liquid through the inlet, shimmy it slightly and then let it sit for about 15 minutes.
