I recently tackled cleaning the engine of my old pickup truck, Bessie, and it was quite the adventure! Bessie’s engine bay hadn’t seen soap and water in… well, let’s just say a long time. I decided to try the Chemical Guys Foaming Citrus Engine Degreaser based on a recommendation from my neighbor, Earl. He swears by it. First, I carefully covered the distributor and alternator with plastic bags – learned that the hard way on a previous vehicle (don’t ask!). Then, I sprayed the Chemical Guys degreaser all over the engine, and it foamed up nicely, smelling faintly of oranges. I let it sit for about seven minutes, as the bottle suggested. The grime was pretty thick, so I used a stiff-bristled brush to really scrub at the stubborn areas, especially around the valve covers. After rinsing with a gentle spray from the hose, I was amazed at the difference! The engine wasn’t showroom-new, but it was significantly cleaner. I even noticed a slight improvement in Bessie’s idle. Next time, I might try Gunk for the really tough spots, but for a general clean, the Chemical Guys degreaser worked great. I made sure to dry everything thoroughly with an old towel before reconnecting the battery, and Bessie started right up. A very satisfying afternoon project, even if I did get a little bit of degreaser in my hair!
