/clean for Slack

/clean for Slack — the easiest way to bulk delete messages in Slack directly from your browser.

Why use it?
Slack doesn’t make it easy to clean up old conversations. This extension gives you full control: bulk delete by channel, DM, or date range — no OAuth, no external servers. /clean for Slack is the ultimate tool to bulk delete Slack messages and purge chat history quickly and safely.

Features:
● Bulk delete messages in channels, DMs, and group chats
● Filter by date, user and reaction type (including starred and pinned messages)
● Built-in handling of Slack rate limits for safe, reliable cleanup
● Admins/owners can delete all messages
● Non-admins can delete only their own messages

How it works:
1. Purchase a license on Gumroad and enter your key in the extension popup
2. Open Slack in your browser
3. Select a channel, DM, or group chat from the dropdown
4. Apply filters and delete messages in bulk

Important notes:
● Your data never leaves Slack — all actions happen locally in your browser
● Deletions respect Slack’s built-in rate limits, so larger jobs may take some time
● Non-admin users are restricted by Slack to deleting only their own messages

Take control of your Slack history today with /clean for Slack.
