You can remove any comment or reply that you have posted, or that someone else has left on your post.
Steps:
Find the comment or reply you want to delete.
Tap the menu (three vertical dots) in the top-right corner.
Choose Delete and confirm.
Good to know:
Deleting is permanent — once removed, it cannot be restored.
You can only delete comments or replies that you've posted.
Comments: Deleted comments leave a footprint (e.g. "Comment deleted") at the bottom of the comments section.
Replies: Deleted replies are removed completely without leaving a footprint.
Instead of deleting, you can also choose to edit your comment.
If a private user comments on your post but you don't follow them, you can still see their post for safety reasons.
