How to clean shared calendars safely

Cleaning a shared Google Calendar requires a little more care than cleaning a personal one — because the deletion affects everyone with access, not just you. Follow these best practices to avoid disruption.

1. Check who has access before you start

Open the calendar's settings and sharing page to see everyone with access and their permission level. This tells you who will be affected by the deletion and who you need to communicate with.

2. Communicate in advance

Tell everyone with access what will be cleared and when. Give them enough time to save anything they need. A 24–48 hour notice is the minimum; longer is better for important shared calendars.

3. Check for future events near the cut-off date

Scroll through the calendar in Google Calendar to confirm there are no upcoming events close to your cut-off date that might accidentally be included in the deletion. Review the event count in WipeAway before confirming — if it is higher than expected, your cut-off date may be capturing more than intended.

4. Export a backup first

Export the shared calendar as an ICS backup before clearing it. Store this somewhere accessible to the calendar owner in case anything needs to be referenced or restored.

5. Run at a low-traffic time

For actively-used shared calendars, run the clean-up at a time when the calendar is unlikely to be in active use — outside business hours, during a holiday period, or on a weekend. This reduces the chance of someone trying to access the calendar while the deletion is in progress.

6. Verify and confirm with the team

After the deletion, confirm with the team that the calendar looks as expected. Give people a few minutes to check before closing out the clean-up process.
