'still covered in germs' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can sometimes mean the same thing.

'dries utensil improperly' is the wordplay.
'improperly' indicates anagramming the letters (I've seen this in other clues).
'dries'+'utensil'='driesutensil'
'driesutensil' with letters rearranged gives 'UNSTERILISED'.
