I use a cleaner-degreaser in a garden sprayer ( the purple stuff). Spray it on everything, let it set for a few minutes and use a low-pressure pressure washer. Be sure to rinse everything well, than take a shop vacuum to remove the water from under the engines. This process is simple and has worked quite well for me. Careful not to get the cleaner in your eyes or on your skin. Good Luck!
