                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



To the Plan Administrator of the
Zep Manufacturing Company
Profit Sharing/401(k) Retirement Plan:


We have audited the accompanying statements of net assets available
for plan benefits of the ZEP MANUFACTURING COMPANY PROFIT
SHARING/401(k) RETIREMENT PLAN as of December 31, 1993 and August 31,
1993 and the related statements of changes in net assets available for
plan benefits for the four-month period ended December 31, 1993 and
the year ended August 31, 1993.  These financial statements are the
responsibility of the Plan's management.  Our responsibility is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan amd perform the audit
to obtain reasonable assurance about whether the financial statements
are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the
financial statements.  An audit also includes assessing the accounting
principles used and significant estimates made by management, as well
as evaluating the overall financial statement presentation.  We
believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for plan
benefits of the Zep manufacturing Company Profit Sharing/401(k)
Retirement Plan as of December 31, 1993 and August 31, 1993 and the
changes in net assets available for plan benefits for the four-month
period ended December 31, 1993 and the year ended August 31, 1993 in
conformity with generally accepted accounting principles.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
      Basis of Accounting -
        The accounts of the Zep Manufacturing Company Profit Sharing/401(k)
          Retirement Plan (the "Plan") of Zep Manufacturing Company (the
          "Company"), a division of National Service Industries, Inc. (NSI), are
          maintained by the trustee on the cash basis of accounting. The
          accompanying financial statements have been prepared using the accrual
          method of accounting by application of memorandum entries.
            
      Investment in NSI Fixed Income Fund -
        A portion of the Plan's assets were commingled in a Fixed Income Fund
          (FIF) together with the assets of certain pension and profit sharing
          plans of other NSI divisions. Investments of the FIF were reflected at
          market values determined by the custodian from publicly stated price
          information. These investments were subject to certain administrative
          guidelines and limitations as to type and amount of securities held.
          The net gain from investments in FIF units in the accompanying
          Statements of Changes in Net Assets Available for Plan Benefits
          reflects interest income on guaranteed investment contracts and master
          notes. On January 1, 1993, investments of this fund were reinvested in
          the NSI Defined Contribution Fixed Income Fund.

        Summarized financial information of the FIF for the period September 1,
          1992 to December 31, 1992 is presented as follows:

      Investment in NSI Master Investment Fund -
        A portion of the Plan's assets were commingled in a Master Investment
          Fund (MIF) together with the assets of pension and profit sharing
          plans of other NSI divisions. Investments of the MIF were reflected at
          market values determined by the custodian from publicly stated price
          information. These investments are subject to certain administrative
          guidelines and limitations as to type and amount of securities held.
          Certain fund assets are allocated to selected independent investment
          managers to invest under the general MIF guidelines. On January 1,
          1993 investments of this fund were reinvested in the NSI Defined
          Contribution Zep Equity Fund.

      Investment in NSI Defined Contribution Zep Equity Fund -
        As of January 1, 1993, a portion of the Plan's assets were placed in the
          Defined Contribution Zep Equity Fund (DC Zep Equity Fund) together
          with the assets of Zep Manufacturing Company Profit Sharing/401(k)
          Retirement Plan for Contract Employees. Investments of the DC Zep
          Equity Fund are reflected at market values determined by the custodian
          from publicly stated price information. These investments are subject
          to certain administrative guidelines and limitations as to type and
          amount of securities held. Certain fund assets are allocated to
          selected independent investment managers to invest under the general
          DC Zep Equity Fund guidelines.

        Summarized financial information of the DC Zep Equity Fund is presented

      Investment in NSI Common Stock -
        As of December 31, 1993, approximately 9% of the Plan's net assets were
          invested in common stock of NSI, a party-in-interest. The Plan's
          investment in NSI common stock was reflected at market value in the
          accompanying financial statements.

      Tax Status -
        The Plan has received a favorable determination letter from the Internal
          Revenue Service dated January 24, 1986, and is qualified under the
          Internal Revenue Code (the "Code") as exempt from federal income
          taxes. The Plan has been amended and restated since receiving the
          determination letter. However, the plan administrator believes that
          the Plan is currently designed and is being operated in compliance
          with the applicable requirements of the Code. Therefore, the plan
          administrator believes that the Plan was qualified and that the
          related trust was tax-exempt as of December 31, 1993.
                                        
      Net Assets Available for Plan Benefits -
        At August 31, 1993, $88,003 of net assets available for plan benefits
          were allocated to accounts of participants who have withdrawn from
          participating in the earnings and operations of the Plan. There were
          no such amounts allocated at December 31, 1993.
                                        
2. TRUST AGREEMENT:
      Under a trust agreement dated September 1, 1993, as amended, Wachovia Bank
        of Georgia, N.A. was appointed trustee of the NSI Defined Contribution
        Plans Master Trust (which includes the DC Fixed Income Fund, DC Zep
        Equity Fund and Common Stock discussed in Note 1). Certain officers of
        NSI were appointed administrators of the Plan's assets together with the
        income derived therefrom.

      Prior to September 1, 1993, the assets of the Plan were included in the
        NSI General Retirement Trust (GRT). Under a trust agreement dated March
        1, 1978, certain officers of NSI were appointed trustee of the GRT and
        were administrators of the Plan's assets and Wachovia Bank of Georgia
        was the custodian.
      
3. PLAN DESCRIPTION:
      The following brief description of the Plan is provided for informational
        purposes only. Participants should refer to the Plan agreement for more
        complete information.
          
      The Plan, as amended and restated effective February 1, 1988, incorporates
        the required standards under ERISA. The Plan is a voluntary, defined
        contribution plan covering all non-union employees of the Company, who
        have attained the age of 21, with at least six months of service.
        Participants may contribute between 1% and 10% of before-tax
        compensation but not to exceed $7,000 (or such larger amount as may be
        determined by the Secretary of Treasury) for any participant in any
        calendar year. Contributions, which are allocated to salaried and
        commissioned participants, are made by the Company in an amount equal to
        5% of net profits, as defined. In addition, the Company contributes an
        amount equal to the same percentage of compensation of non-union hourly
        employees as the 5% bears to the total remuneration of salaried and
        commissioned participants. The total of these amounts can be increased
        for any additional discretionary amount determined by the Board of
        Directors of NSI. The maximum compensation with respect to any
        participant for purposes of employer contributions to the Plan is
        $35,000.
      
      During December, 1993, the Plan was amended and restated to allow
        participant directed investments effective January 1, 1994. In addition,
        the Plan year end was changed from August 31 to December 31. Thus, the
        accompanying financial statements are for the year ended August 31, 1993
        and the four month period in the short plan year ended December 31,
        1993. The Plan, as amended and restated, does not permit employer
        contributions during the short plan year.
          
      Non-vested employer contributions are forfeited upon withdrawal
or termination, as defined, from the Plan and are allocated to
remaining participants. All expenses of the Plan were paid by
the Company during 1993 and 1992. Vesting of employer con-
tributions occurs on an increasing scale ranging from 20%
vesting after three years of service, as defined, to 100%
vesting after seven years of service. Participants are always
fully vested in their individual contributions.

      Although the Company intends for the Plan to be permanent, the Plan
        provides that the Company has the right to discontinue contributions or
        to terminate the Plan at any time. In the event of termination, each
        participant shall be vested with the balance of his account and his
        proportionate share of any future adjustments or forfeitures.
