                    SAFETY-KLEEN REPORTS INCREASED REVENUE
                    --------------------------------------
                  AND EARNINGS FOR THIRD INTERIM PERIOD 1996
                  ------------------------------------------


     Elgin, Illinois -- September 30, 1996 -- Safety-Kleen Corp. (NYSE:SK) today
announced results for the third interim period ended Sept. 7, 1996. Consolidated
revenue for the 12-week period was $213 million, an increase of 8% compared with
the similar period in 1995. Net earnings rose to $14.0 million, an increase of 
26% over the $11.1 million reported in the third quarter of 1995. On a per share
basis, earnings were $0.24, compared with $0.19 in the same quarter one year 
ago.

     For the first thirty-six weeks of 1996, consolidated revenue increased 5% 
to $626 million. Net earnings rose 15% to $40.7 million from $35.3 million 
during the same period one year ago. Year-to-date earnings per share were $0.70 
compared with $0.61 in 1995.

     Commenting on the results, President and Chief Executive Officer, John G. 
Johnson, Jr. noted, "Revenue growth year over year improved from 4% in each of 
the first two quarters of the year to 8% in the third quarter. The stronger 
growth in the third quarter reflects improvement in our Industrial Parts Cleaner
Service business as well as in our Fluid Recovery Service. In addition, our Oil 
Recovery Service revenue increased 19% compared with the third quarter of 1995 
reflecting, in part, the additional revenue contribution from the 1996 
acquisition of Industrial Service Corp. The integration of this acquisition as 
well as two

smaller acquisitions in the oil recovery business have extended Safety-Kleen's
presence in the central and western United States." Johnson noted.

     Johnson further added, "We are pleased to report that our fuel plants and
recycle operations have continued to run smoothly and efficiently in 1996."
Reflected in the earnings comparison are unusually high costs incurred in the
third quarter of 1995 associated with the disposal of waste-derived fuels due to
kiln outages.

     During the third quarter, Safety-Kleen acquired the business of a parts
cleaner and paint refinishing service company with operations in both the United
States and the U.K.. The acquisition should ultimately add 11,000 customers and
15,000 units. Approximately 3,500 of these units were signed up by the end of
the third quarter. "Revenue from the Automotive/Retail Repairs Service increased
3% in the third quarter of 1996 compared with the similar quarter in 1995. The
increase is a result of acquisitions as well as new service offerings."

     Johnson concluded, "We are pleased with the acceleration of revenue growth 
in the third quarter and expect further improvement in the remaining quarter of 
the year."

     Safety-Kleen is a leading service company specializing in the recovery and
recycling of waste fluids, including the collection and re-refining of used 
motor oil. Safety-Kleen stock is traded on the New York Stock Exchange under the
symbol "SK".
