How do I delete all my tweets that I can't see?

I’m a Twitter user from the day the Twitter was launched. There are two things to keep in mind: Twitter API has many updates, so only the services that constantly update their programming actually does the work Twitter API has limited access only to 3000 recent tweets, so tweet archive upload is the only way how to delete all the tweets. Otherwise older tweets are still visible to google and others. Recently I wanted to delete a bunch of my old tweets so I tried all possible services. In general there are many spam services that do not work (tweets are not deleted in the end duo to reasons mentioned above)I think the best one definitely is: https://www.tweetdeleter.com/en. It has broad range of features. I liked that I could also upload my full archive of tweets and delete even oldest ones. If you have for example 10 000 tweets you can delete only 3000 recent ones, so archive upload is the only option to clean your profile completely. So far only the one mentioned above supports it. The keyword search feature is also very useful. The second best probably is http://www.deletetweets.co/en although the design and usability is not as good as for TweetDeleter. Other services basically allow you to delete only all tweets what I didn’t want to do (and even that functionality for most of them do not work due to 3000 limit or because the system is outdated)! Hope my review helps. :)
