Jeanie, I think you should maybe get a good old portion of fish + chips....a bit of salt and tartar sauce....sit in there and pretend you're having dinner with me....
As everyone has said - vinegar (although maybe yucky smelly) is a wonderful cleaner/deodoriser/everything-er! Bet you didn't realise you were doing your car such a favour.....
To neutralise ANY 'bad smells' - I always use Naturally Activated Charcoal xxx
