GT outpost

[Louridder]

Hi
How is everyone? I just bought this GT Outpost mountain bike and wanted to hear what you all think about it? It’s older but rides very nice. Any advice on how to clean surface rust and what I should do to clean it up and maintain/ tune it for optimal performance? I’m new so any advise would help
Thanks
