Here are some tools that you can use to clean up YouTube videos from the ad clutter:
1 SafeShareTV is a service that can be used to watch YouTube videos without viewing the ads, links, comments and the related videos around them.
2 ViewPure is another tool to watch safe videos on another screen. Just copy and paste your link and watch it in a separate screen.
3 YouTube XL is a service from YouTube for watching videos on a large screen without ads and comments. Another way to get rid of all the extras is to write «quiet» in front of the YouTube video address. It takes you to a safe page where you can watch the YouTube videos.
4 CleanVideoSearch helps you to search YouTube videos without viewing the comments, ads, and the sidebar. It also allows you to choose how many videos you would like to see on each page.
5 Clea.nr deletes all the distractive features around the videos and it also allows you to search Youtube without seeing any extras.
