80% isopropyl alcohol. Use a soft brush wet with some of the alcohol. Brush around the affected areas. Let it dry and that’s all for me.

Just buy a good 3d printer for your first. Sure, it’ll cost money, but the heartache of constant troubleshooting and tweaking can just suck the fun out of the hobby if you just need this print to succeed.
Prusa Mini+ (I think) Bambu A1 Mini (this would be my #1 starter printer before the security updates they done)
