UPDATE: 08/12/2020
Now it is easy to delete all your likes.
- Login to your google account.
- go to this link (https://myactivity.google.com/page?utm_source=my-activity&hl=en_GB&page=youtube_likes)
- on the left side of the page you will find an option called delete all.
(Note: This will delete your your likes and dislikes on YouTube videos from all time. Your activity will be permanently deleted from your account and no longer tied to you.)
Outdated Solution.
How to remove all your liked videos in your liked videos playlist on youtube. As you may already know it is impossible to delete the “liked videos playlist” itself. So we will have to remove all the items in it. Doing that one by one will take a long time.
So the below solution will help to remove all videos at a time.
open you-tubeclick on liked videos playlistclick on edit option (It will be under playlist name)in the address tab add the following to the URL “&advanced_settings=1&disable_polymer=1”open browser console (by pressing Ctrl + Shift + j)Chrome: Windows: Ctrl + Shift + J | Mac: Option + Cmd + JFireFox: Windows: Ctrl + Shift + K | Mac: Option + Cmd + KOpera: Windows: Ctrl + Shift + J | Mac: Option + Cmd + JEdge: Press “F12 “and then click on the “Console” tab.Safari: Option + Cmd + C (You have to turn on the “Develop menu” . Click on Safari in upper left corner >> Preferences >> Advanced tab. >> At the bottom check the box next to “Show Develop menu in menu bar”.)
Then insert the java-script code given at the bottom exactly as it shows.reload the page and do again until your playlist is cleared. (or you can scroll down and click load more to show more items in the playlist prior to running the code)Done!
var items = $('body').getElementsByClassName("pl-video-edit-remove-liked-video"); for(var i = 0; i < items.length; i++){ items[i].click(); }

When I put in the coding bit it says undefined, and after I hit enter nothing is deleted and I get a few red messages in the box saying err_blocked_by_client. Any change there’s another way to delete them all?
