I do not find anything wrong with her behavior from what you have mentioned. Cleanliness is part of everyday life, and some people are a little extra cleanliness conscious. It necessarily doesnt have to be obsession.She panicking about little things is also quiet normal unless you notice it happening everyday and disturbing her everyday life activities.

will help you and your wife understand if everything is normal.
