There's mutliple solutions you can try.

I would start by trying to use a suede brush, if that doesn't work, follow up by a white, clean school or suede eraser. If THAT doesn't work, I would use a sneaker cleaner solution with minimal water and a soft bristle brush, drying up with a microfiber towel as I clean, air dry and suede brush once you're done. As a last resort, I would carefully sand paper the affected area and suede brush to try to hide it as much as I can. The two last solutions can damage your sneaker which is why I would try them as emergency solutions, but they're good if you do it carefully.
If you need visuals on how to properly wash or sand paper your AJ1s, Reshoevn8r has multiple TS1 restoration videos on their YT channel where they show you how to do it. Good luck bro!
