SAFETY-KLEEN REPORTS RECORD REVENUE, 6% GAIN IN NET EARNINGS FOR THE SECOND 
INTERIM PERIOD.

ELGIN, IL, July 7, 1995 -- Donald W. Brinckman, Chairman of Safety-Kleen Corp., 
announced today that revenue for the Company's second interim reporting period 
increased 11% to a record $203 million. Net earnings increased 6% to $12.1 
million. Earnings per share was $.21, up from $.20 in 1994. Year-to-date revenue
increased 10% to $398 million and net earnings increased 14% to $24.2 million. 
Year-to-date earnings per share were $.42 compared to $.37 in 1994.

Revenue of the North American Automotive/Retail Repair Service was up 1% in the 
current quarter and revenue of the North American Industrial Parts Cleaner 
Service was up 4%. Total parts cleaner units in service worldwide increased by 
7,400 during the current quarter. The total units in service increased 
approximately 34,000 units or 6% from the end of the second quarter 1994. 
Approximately 9,000 of these units resulted from acquisitions. The Company 
continued to convert customers to the new cyclonic parts cleaner technology. At 
the end of the second quarter, 142,000 cyclonic parts cleaner machines were in 
service at customers, an increase of 39,000 units from the beginning of the 
year.

Brinckman said, "We have experienced good growth in our Industrial Fluid 
Recovery Service in North America, with revenue up 15% over last year to $28.9 
million in the current quarter. We have continued to add Branch Industrial 
Managers to increase our penetration of the market. Our Oil Recovery Service 
revenue grew 13% in the current quarter to $31.0 million. The net earnings of 
this business was $1.3 million in the current quarter, up from break-even last 
year. The improved profitability stems largely from increased prices for 
collection of used oil and increased prices for lubricating oil products. 
Revenue of our European operations grew 18% to $23.2 million, with approximately
two-thirds of the growth resulting from changes in currency translation rates."

"Revenue of our new Imaging Services business was $7.1 million in the current 
quarter compared to less than $100,000 last year. However, this business 
continues to incur higher than expected startup losses as we integrate the 
acquisitions we made in late 1994 and early 1995 and train our branch service 
representatives to service this market."

"Our year-to-date operating margin of 12.4% improved from 11.7% in 1994. We 
expect continued margin improvement for the full year 1995 due to continuing 
conversion of customers to the cyclonic parts cleaner service, improved pricing 
in selected markets, continued growth in the Fluid Recovery Service and a 
reduction in Imaging Services startup losses."
