Sure, I can guide you through the process of removing duplicates from your Spotify playlists. Here's a step-by-step guide:

1. Open your Spotify app on your computer.
2. Navigate to the playlist you want to edit.
3. Click on the three-dot menu icon on the right side of the screen.
4. From the dropdown menu, select "Playlist Radio."
5. Now, go back to your playlist.

If you want to do this more efficiently, you can use third-party apps or websites such as "Spotify Dedup." Here's how you can use it:

1. Go to the Spotify Dedup website.
2. Click on "Log in with Spotify" and authorize the app.
3. The website will automatically list all your playlists.
4. Click on "Remove duplicates," and the app will automatically remove all the duplicate songs from your playlists.

Please remember to always be careful when providing your Spotify details to third-party apps or websites. Make sure they are trustworthy and have positive reviews.
