Recently I took my Honda CR-V off road in Mexico (I was visiting an orphanage in a remote area, don't judge me). The car came back to the States literally caked with mud, including everything under the hood. Conejo Auto Detail steam cleaned the engine compartment for me. They were fast, very professional, courteous, and when the car was ready they showed it to me running with the hood up so I could easily see the quality of their work (well worth the $50 estimate). The engine sparkles like new. I am totally pleased with the job they did and I heartily recommend them.
