Sign into iCloud
Open the website iCloud.com in any browser on your computer.
Enter your Apple ID and password und click the “Sign in” arrow.
Go to Reminders
On the home screen of your iCloud account, you have to choose “Reminders”.
In the sidebar on the left side, click “Reminders” or another list, of which you want to delete completed reminders.
Below the name of the list, you will see the number of completed tasks. Click the arrow next to it.
It will open a drop-down menu, in which you will see all the completed tasks (sorted by completion date).
Delete all Reminders
On the right side, you will now encounter a new button: “Clear Completed”. By pressing this button you can irreversibly delete all completed reminders in this list. This process has to be confirmed again on a pop-up window and then it’s all cleared out.
