| Basis of Presentation                                     | Basis of PresentationThe unaudited interim condensed consolidated financial statements for the three and nine months ended March 31, 2022 and 2021, in the opinion of management, reflect all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the consolidated results of operations, financial position and cash flows of The Clorox Company and its controlled subsidiaries (the Company) for the periods presented. However, the financial results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year or for any other future period. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted or condensed pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). The information in this report should be read in conjunction with the Company’s Annual Report on Form 10-K filed with the SEC for the fiscal year ended June 30, 2021, which includes a complete set of footnote disclosures, including the Company’s significant accounting policies. |
| Recently Adopted Accounting Standards                     | Recently Adopted Accounting StandardsIn December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (ASC 740): Simplifying the Accounting for Income Taxes,” which removes certain exceptions to the general principles in ASC 740 and amends existing guidance to improve consistent application. Certain amendments must be applied prospectively, certain amendments must be applied on a retrospective basis, and certain amendments must be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings. The Company adopted this standard as of July 1, 2021. The adoption of this new standard did not have a material impact on the Company’s condensed consolidated financial statements.                                                                                                                                                                                                                                                                                                                                                                                                                                          |
| Fair Value Measurement                                    | Fair Value of Financial InstrumentsFinancial assets and liabilities measured at fair value on a recurring basis in the condensed consolidated balance sheets are required to be classified and disclosed in one of the following three categories of the fair value hierarchy:Level 1: Quoted market prices in active markets for identical assets or liabilities.Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions.As of both March 31, 2022 and June 30, 2021, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis included derivative financial instruments, which were classified as either Level 1 or Level 2, and trust assets to fund the Company’s nonqualified deferred compensation plans, which were classified as Level 1.                                                                                                                                                                                                                                                                                                                           |
| Segment Results                                           | The Company operates through strategic business units (SBUs) that are also the Company’s operating segments. The SBUs are then aggregated into four reportable segments: Health and Wellness, Household, Lifestyle and International. Certain non-allocated administrative costs, interest income, interest expense and various other non-operating income and expenses are reflected in Corporate. Corporate assets include cash and cash equivalents, prepaid expenses and other current assets, property and equipment, operating lease right-of-use assets, other long-term assets and deferred taxes.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               |
