do you know from experience? It is a cleaner also

As I said I been using it for many, many years, and you must spray and wipe it off.

Most actually evaporates due to its chemical composition leaving a little film (the mineral spirits/oil) behind.

Works very, very well. Sure they make other products also, but this is def a good one for this purpose.

edit: from WD 40 site: cleans and protects engine bay
