A rust inhibiting process 100 for cleaning and protecting a target object 902 is disclosed. Comprising mixing at least a rust inhibitor 620 and a fluid 618 into a slurry mixture 608, spraying the slurry mixture 608 at the target object 902 from within a reservoir 610 of a slurry blasting system 202, separating a tarnished top layer 906 and a parent metal 904 of the target object 902 with a slurry stream 908, cleaning the parent metal 904 with the rust inhibitor 620, preventing the parent metal 904 from impregnating with contaminants during cleaning with the rust inhibitor 620, and protecting the parent metal 904 with the rust inhibitor 620 after spraying is complete. The slurry stream 908 comprises the slurry mixture 608 of the slurry blasting system 202 being sprayed with the slurry blasting system 202. The slurry blasting system 202 comprises a tank 204.
