How to get rid of the diesel smell in the car?

Clean with 100 straight gasoline first, then scrub with alkaline cleaner, and scrub with foam cleaner after drying.

At present, the most commonly used oil washing method is to wash oil with acid and alkali.

Alkali refining is to treat petroleum products, such as gasoline, diesel oil and lubricating oil, with caustic soda aqueous solution, which can remove oxides and sulfides and remove the residual sulfuric acid in the acid refining process. Acid refining and alkali refining are often combined, so they are called acid-base refining.
