My answer would be to not have bought the plant in the first place.
Ideally throw it away, ich can live on any surface, even the inside of a bag.
Throw the entire lot away, it's not worth the risk just for one plant.
Id get a weak bleach solution. Dilute it in water and let the plant soak in it for 1-2 minutes. This will get rid of any germs/bacteria on the plant.
Once the plant is taken out, rinse it under water a few times, then let it air dry.![]()
