'some antiseptic' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'ten to perform online' is the wordplay.
'ten' becomes 'IO' (IO resembles l0).
'to perform' becomes 'do' (both can mean complete an action).
'online' becomes 'l' (I can't justify this - if you can you should give a lot more credence to this answer).
'io'+'do'+'l'='IODOL'

'with' acts as a link.
