I've been experimenting with various Linux distros and am finally ready to commit to one. I'm looking to do a clean install of Arch Linux, but I've previously had a few different systems on my machine. Do I need to completely erase the old operating systems, or will the installation process handle that for me? Last time I did this, I ended up with leftover partitions that were tricky to get rid of. What should I do this time?

To ensure a completely fresh start, you can opt for a full disk install, which will remove all data. The only things that might remain are old boot entries, but they won’t affect your daily use at all.
You can choose a clean reinstall during the setup, but formatting your drive is the best way to ensure you're starting fresh.
If you format or repartition your drive during the installation, everything on it will be erased. For that "clean" install feeling, that's definitely the way to go! Just a heads up: if you’re uncertain about a basic question like this, Arch might not be the easiest starting point, but hey, it's your choice! Cheers!
When you reach the installation point that asks where to install, just select the whole disk or choose the ‘something else’ option. Make sure to create a new GPT partition table to wipe out any previous data.
