How would you go about cleaning this aquarium?

 The only living thing inside is algae. I want to start the whole tank new. It hasn't been touched in over a year. I don't want to hurt any future fish, or have the algae not completely eradicated. 
 I will be removing everything from the tank, and spraying down. I have seen a few things about hydrogen peroxide and magic erasers. I will be keeping the lights off for about a week before attacking it. Any suggestions?
