Did you keep this sick leopard gecko in the same room as your BP? Did you handle the sick leopard gecko and then go pick up your healthy snake? I understand why you’re experiencing some anxiety, but I think you may be trying to kill a fly with a shotgun, so to speak.

If your enclosures are clean, wash your hands between handling animals, and you quarantine new arrivals you should be fine. I wouldn’t go wiping my snakes down with F10 or chlorhexidine regardless of if it may or may not have any adverse effects.
