24 hours ago I accidently washed my pareve air fryer with the sponge that I use to wash my dairy utensils, does this mean that my air fryer is now dairy and is there a way to kasher it into pareve, Thank you :)

ב"ה Shalom I assume your sponge had soap or some other distasteful material in it and therefore your air fryer remains pareve . It should just be rinsed properly. All the best
