How to Get Rid of the Smell of Spilt Milk

Read on to find out how to banish that sour milk smell from your home with our tips and tricks. 

Spilling milk is a pain. Whether it’s on the carpet, the bed or you’ve spilt milk on couch furnishings, such as cushions and throws, the problem is the same! That problem, of course, is the smell.

How to get rid of spilt milk smell


That sour milk smell is awful and definitely not what you want in your home. To help you get rid of it before it’s too late, we’ve put together this handy little guide with everything you need to know.

Soak up the spilt milk


The first thing to do, no matter whether you’ve spilt milk on mattress and bedding materials or in the interior of your car, is soak up the milk. Blot using a towel – don’t scrub, you’ll just be helping the milk to absorb into the fabric!

Getting rid of spilt milk on washable items


If you’ve spilt milk on something that can be washed, such as bedding or clothing, after blotting up the excess, put the item straight in the washing machine on a cold wash. Make sure you use a trusted detergent such as Persil Bio Liquid, or something with a strong (and more pleasant) scent such as Surf Tropical Lily & Ylang Ylang Liquid, which are designed to leave a lasting, fresh scent on clothing.

Wash them as you normally would and leave to dry. The spoiled milk smell should be gone before it’s even had a chance to appear.

How to get milk out of sofa and non-washable items


If you’ve spilt milk on couch cushions, the carpet or something else that can’t be thrown in the washing machine, you need to go about things a bit differently after blotting.

The best method is to use baking soda. Simply pour a good layer over the area the milk was spilt, leave it to get to work overnight or for a day or so, and then hoover it all up. Easy!

This can also be used on washable items before machine-washing with detergent if the sour milk smell is really bad.

How to remove spilt milk stains


If you’re left with a stain even after you’ve learnt how to get rid of spilt milk smell and taken the steps, use a stain remover spray. Make sure it’s safe for the sort of fabric that’s stained and try on a little patch before using all over.

Once you know how to do it, getting rid of the spoiled milk smell left behind after you’ve spilt milk is actually pretty easy! Just follow these steps and you’ll never have to put up with the smell of bad milk in your home ever again.

Top Tip


Spilt milk on the go and don’t have access to a washing machine? Dab the stain with a paper napkin and flush out the stain with cold water and a little detergent, as warm water will set this protein-based stain.    

Key Steps


  • Dab the stain to soak up excess milk.
  • Flush out the stain from the back of the fabric with cold water if you can’t wash the item immediately.
  • If the stain is dried in, soak the item and rub a small amount of detergent into the stain.
  • Wash the item at a cold temperature in the washing machine with Persil Bio Liquid (or Surf Tropical Lily and Ylang Ylang Liquid if you want to give your garment a nice scent).
  • Let the garment air dry and check that the stain is gone.
