Bergamot... rosemary... brandy. And combination of the three, although if you're only able to get single scents, something like sandalwood, or bergamot alone will do.

[ did you know... astarion has a canon scent. and it's bergamot, rosemary and brandy... ]

Individual scent alone would do if a candle isn't possible. Something with a dropper, so it could be strategically placed where the unpleasant scents are hardest to remove.
