Let the degreaser sit for 3-5 minutes, but don't let it dry out. 5. Scrub: Use various brushes to scrub off the dirt, grease, and grime. Be careful not to damage any parts. 6. Rinse: Once you've scrubbed away the dirt and grease, rinse the engine with your hose or pressure washer. Make sure all the degreaser is rinsed away, as it can cause damage if left on for too long. 7. Dry: Once it's clean, dry the engine using a cloth or, better yet, let it air dry. If necessary, use compressed air to blow water out of tight spots. 8. Remove Protective Coverings: After everything is completely dry, remove the plastic bags used to protect sensitive parts. 9. Run Engine: Start your vehicle and let the engine run for a few minutes. This will help evaporate any remaining water in the engine area.
