For thick, greasy grease and filth, it is necessary to let it rest for more than five minutes otherwise.

6. Scrub the Engine with Brush until Clean

 

 

You must scrape the dirt to remove it after soaking it. You can use a synthetic bristle brush for this task. Take the brush and scrub the area with it in a gentle manner. Scrub it again with the second degreaser application if it comes off slowly. When scrubbing, you must put on protective clothing, such as gloves and safety glasses. This will shield your skin and eyes from dangerous degreaser chemicals.
