Fishy smell in the car

The smell may just be coming from food that has gone mouldy, in which case your car will require a deep clean. You can undertake this cleaning process yourself or employ a professional cleaning service if you think that you cannot tackle it yourself.

If you do it yourself at home, a great DIY remedy, is white vinegar and baking soda. Create the mixture then apply it heavily to the smelly area, leave it to soak in a while then soak up whatever of the mixture is left.

If the stain is in your car seat or floor, you can rent handheld Vaxing equipment from most supermarkets - they'll give your upholstery the ultimate clean! Smell still lingering?

Car smells like dead fish

The smell of dead fish is far from a pleasant one, nor are the mental images that it conjures.

Sadly, the unpleasant fishy smell could be coming from a dead animal in your blower motor. The animal may have crawled inside of your car at night for shelter and warmth, then has unfortunately been obliterated when the engine switched on.

This is undoubtedly an unfortunate clean-up job, but it is the only way to eradicate the smell before it becomes truly pungent by embedding itself in the car upholstery.

Whilst this is a problem you can diagnose yourself, your best bet to resolving it is to drive to a local car wash and see what under the hood cleaning service they offer. Otherwise... could it be an actual dead fish hidden somewhere in/on your car?! Worth a check!
