Yes, there are ways to clean up your Edge bookmarks. You can try using the built-in features of Microsoft Edge itself to manage and organize your bookmarks. Simply right-click on a bookmark and select options like "Delete" or "Move to folder" to clean up your bookmarks manually.
Alternatively, you can also try using third-party applications such as "EdgeManage" or "StorURL" which are specifically designed to manage and organize bookmarks in Microsoft Edge.
