Default [Q] Please help. I want to remove lucky patcher and don't know how

I had lucky patcher installed and decided I didn't like it and it wasn't for me. But I feel like a simple uninstall of the app doesn't get rid of everything. I'm a little worried about files being left behind and such. It makes me nervous. I uninstalled the app from my phone and clean master said there was 90 mb left behind so I said to clean it. Did I do this right?
