How To Clean Milk From Carpet And Remove The Smell Permanently

spilled milk on carpet

What is the worst thing that could happen to your carpet? For many people, spilling milk on the carpet is certainly not the biggest deal, but not until things get real. Because of the high absorbency nature of carpets, milk can easily seep deep into the fibres – leaving persistent stains and unpleasant odours.

You may not notice the stains or nasty smell at first. With time, however, the bacteria in milk will develop and covert the natural sugars into acetic and lactic acid. As a result, the stained area will turn yellow and start giving off a sour smell.

The presence of protein is what makes milk stains on carpets such a pain to clean. When protein dries out, it usually hardens. Hardened proteins prove quite challenging to rehydrate. Don’t lose hope, though!

With patience and the correct carpet cleaning methods, you can fix the milk stains and leave your carpet smelling fresh once again. Before you start calling a professional carpet cleaning company we want to steer you in the right direction. That is why we have created this detailed guide on how to remove milk stain and smell from the carpets.

How to Clean Milk From Carpet

Before we explain the methods for removing milk from your carpet, we would like to share a few tips that might make a whole lot of difference in your cleaning process. 

Blot The Stained Area Dry Immediately

Don’t give the milk time to penetrate and settle in the carpet fibres or underlayment. The longer milk sits in your carpet, the smellier it will get. This is especially true if you’re dealing with a spill of full-fat milk. Skim milk is typically not considered an urgent case unless it is flavoured.

Regardless, though, we advise you to act immediately by blotting the excess milk using a paper towel or a white washcloth. Be sure to continue blotting the affected area until you have soaked up all the moisture from the carpet. 

Gently Scrape Away Dried Milk

Maybe it is your child who spilt the milk on the carpet, and you were not around to fix the mess immediately. If the stain has hardened, don’t fret. There is a way to tackle the issue and restore your flooring material.

First off, make sure you remove as much residue as possible. A butter knife will get the job done. Once no residue of dried milk comes off the carpet, make sure to vacuum the stained area to suck up any excess debris.

Test Cleaning Materials On A Small Inconspicuous Area

Unless it is your first time to clean carpet stains by yourself, you have probably come across this piece of advice. The testing technique helps determine if a product is safe, preventing you from potentially discolouring or damaging your expensive carpets. 

Don’t Treat Milk Stains With Hot Or Warm Water

As we mentioned earlier, milk contains proteins. Cleaning it with hot or warm water can set the stain. High temperature also intensifies the unpleasant smell.

Always Read The Ingredients Of Every Cleaning Product

Avoid detergents that contain any form of bleach. While bleach is very effective at getting rid of a wide range of household stains, don’t try it on your carpet. The chemicals used are powerful enough to strip the colour from your carpet fibres.

Mix Bleach With Ammonia

In case no one has ever told you before, combining the household bleach and ammonia is extremely dangerous. When mixed, they release toxic fumes that can irritate eyes, nose, and lungs. Exposure to high concentration can be fatal..

Always Wear Protective Gloves When Cleaning Using Commercial Products

Commercial cleaning products contain chemicals. If your skin gets exposed to the chemicals, they can easily strip away the skin’s oil barrier. Strong chemicals can burn your skin.

Now let’s dive into the part you have probably been searching for – methods for cleaning milk stains out of your carpet. 

Milk Stain Removal From Carpet With Dish Soap And Ammonia - Method #1

Protein-based stains like milk can be removed from carpet fibres with mild dish soap followed by ammonia.

What you will need:

  • Paper towel, sponge, or cloth
  • Water
  • Bowl
  • Tablespoon
  • Cup
  • Dish soap
  • Ammonia
  • Step 1:  After blotting the stain dry or removing the residue of dried milk, pour 2 cups of lukewarm water in a bowl and add a tablespoon of dish soap. Stir the ingredients gently.

  • Step 2: Take a clean, soft cloth and dip it into the solution. Make sure you squeeze out any excess of the cleaning solution until the cloth is moist, not wet.

  • Step 3: Using the damp cloth, gently rub in small, circular motions from the outside, towards the centre of the stain. Take as much time as possible to weaken and break the molecular structure of milk stain.

  • Step 4: Blot the area once more with a dry cloth. Getting rid of the stain should be a lot easier if the dish soap solution has worked.

  • Step 5: If you are not getting the results expected, try cleaning the area with a mixture of lukewarm water and ammonia (same ratio like in step 1)

  • Step 6: Dampen a clean sponge in the solution and start blotting the stain lightly. Repeat the process until the milk stain is gone.

  • Step 7:Rinse the area with a new sponge moistened with cold water. Once done, soak up as much moisture as you can with a clean, dry cloth.

Milk Stain Removal From Carpet With A Laundry Detergent Paste - Method #2

This is an effective technique if you are dealing with fresh milk stains. 

What you will need:

  • Paper towel, sponge, or cloth
  • Water
  • Bowl
  • Tablespoon
  • Cup
  • Dish soap
  • Ammonia
  • Step 1: Using a paper towel, blot the excess milk that’s visibly wet on the flooring material.

  • Step 2: Lightly spray some cold water on the stain. It is because the laundry detergent paste works best in a misted area.

  • Step 3: Put powdered laundry detergent in a bowl and start adding cold water while mixing until you have a smooth paste.

  • Step 4: Gently work the paste into the fibres using a toothbrush.

  • Step 5: Take a clean towel soaked in cold water and rinse the milk stain. Afterwards, use a dry towel or cloth to pat dry the spot.

  • Step 6: Vacuum the carpet thoroughly before leaving it to dry.

Milk Stain Removal From Carpet With Cornstarch - Method #3

Yes, you heard that right. This kitchen cooking ingredient doubles as a milk stain remover, thanks to its fast-absorbing properties. It is also easy to use.

What you will need:

  • Dry cloth, sponge, or paper towel
  • Cornstarch
  • Vacuum cleaner
  • Dull knife/spatula and a spray bottle (if milk has dried) 
  • Step 1: Like in the previous methods, you have to blot the stain immediately after the milk spills on your carpet. If milk has dried, mist the stained part after removing as much residue as you can.

  • Step 2: Sprinkle the powder evenly over the soiled spot. Leave the cornstarch there for 30 minutes or more to absorb the remaining traces of milk from the fibres.

  • Step 3:  Run a vacuum cleaner over the area to suck up the cornstarch residue. You can repeat the procedure as necessary. 

Milk Stain Removal From Carpet Using Isopropyl Alcohol - Method #4

When milk has already dried, isopropyl rubbing alcohol might be your best weapon to counter the problem.

What you will need:

  • Dry cloth, sponge, or paper towel
  • Butter knife
  • Isopropyl alcohol
  • Step 1: You will need to scrape away the flakes with a butter knife.

  • Step 2: Moisten a sponge or terry cloth with isopropyl alcohol.

  • Step 3: Work the rubbing alcohol into the stained fibres. That milk stain will be transferred to the cloth as the alcohol evaporates. Repeat the procedure as many times as possible until the stain is gone.
For larger stains, you should carefully spray the alcohol onto the carpet until the upper layer gets saturated. Then, use a clean, dry washcloth to rub the isopropyl alcohol into the fibres.

Milk Stain Removal From Carpet With Washing Powder - Method #5

You can try out a gentle washing powder, whether it is a case of fresh or dried stains.

Here’s what you will need:

  • Washcloth, sponge, or paper towel
  • Spray bottle
  • Dull knife
  • Toothbrush
  • Gentle washing powder
  • Water
  • Vacuum cleaner 
  • Step 1: Blot the stain with a dry cloth or remove residues of dried milk using a dull knife.

  • Step 2: Spray the stained spot with water. Just like powdered laundry detergent, washing powder works best when the stain is moist.

  • Step 3: Wet your toothbrush before dipping it in the washing powder.

  • Step 4: Apply it to the milk stain gently in a circular motion.

  • Step 5 : Rinse the spot with a clean, wet washcloth.

  • Step 6: Run a vacuum cleaner over the carpet to straighten the fibres back up.

Milk Stain Removal From Carpet With Hydrogen Peroxide - Method #6

Hydrogen peroxide is another carpet stain remover worth your attention. It is effective against several types of stains, including milk stains.

What you will need:

  • Paper towel or washcloth
  • 3% hydrogen peroxide
  • Dropper 
  • Step 1:  After blotting the stained area with a paper towel, apply hydrogen peroxide using a dropper. Strictly use 3% hydrogen peroxide, as a higher per cent might ruin your beautiful flooring material.

  • Step 2:  Give the cleaning solution time to work its magic. Precisely, you should proceed to the next step when foaming stops.

  • Step 3:  Take a dry washcloth and blot.
If the milk stain persists, you can try applying a soft paste of hydrogen peroxide and non-gel toothpaste. The combination has a much stronger effect on tough stains.  
You will need to spread the paste on the carpet and let it sit there until it’s dry. Next, run a vacuum cleaner over your carpet to pick up the residue. Please keep in mind that no rinsing is required.

How To Get Milk Smell Out Of Carpet

You have finally managed to clean the milk, but after the carpet dries up, you notice some lingering odours of sour milk. We understand the frustration. But before calling a professional carpet cleaner, you will want to try out the following common remedies for refreshing carpets.

How To Remove Milk Smell From Carpet With Vinegar - Remedy #1

Method 1
Step 1:
Dilute white vinegar with cold water in a bowl in a ratio of 1:1.

Step 2: Pour the solution into a spray bottle.

Step 3: Spay it directly on the spill area to break down any remaining milk enzymes. Ensure the area gets drenched with the vinegar solution for the best results.

Step 4: Let the vinegar solution sit on the carpet for at least an hour before you can blot dry with a paper towel or dry cloth.

The smell of vinegar wears off as it dries. Your carpet should smell fresh once the vinegar smell disappears completely. 


Method 2
Step 1: Fill a few bowls with undiluted vinegar. In this case, you can use any vinegar type.

Step 2: Place the bowls of vinegar around the stained area of your carpet.

Step 3: Leave them overnight if it was a minor milk stain. For large stains, let the vinegar stay for a few days. 

However, you need to be careful with this method, especially if you have kids or live with other family members. The last thing you want is for them to step on the bowl and wet the carpet with loads of vinegar. It is best to lock the room where you have the carpet or surround it with something.

How To Remove Milk Smell From Carpet With Baking Soda - Remedy #2

  • Step 1:  Sprinkle bicarb soda (baking soda) over the spill area. Pour enough baking soda to create a visible coat.

  • Step 2: Spread it evenly with a soft carpet broom.

  • Step 3:   Let it sit overnight to absorb the unpleasant odours.

  • Step 4: Loosen the bicarb soda with your hands before vacuuming the area to remove residue.

You can always apply this method if your carpet smells awful after a DIY cleaning. 

How To Get Milk Smell Out Of Carpet Using Borax Powder - Remedy #3

  • Step 1: Sprinkle a generous amount of borax over the smelly area.

  • Step 2:  Use a broom to spread the powder evenly.

  • Step 3:  Leave it for about half a day.

  • Step 4: Vacuum to the borax coated part first before running the vacuum cleaner over the entire carpet. 

Borax is an excellent alternative to bicarb soda. It can absorb common household odours, including the sour milk smell. 

How To Get Milk Smell Out Of Carpet Using Coffee Ground - Remedy #4

  • Step 1: Sprinkle dry, unused coffee grounds over the smelly area. Do not use the damp coffee grounds because they can make a mess and even stain your carpet.

  • Step 2: Leave the coffee grounds to work their magic for a few hours, preferably overnight. That would be enough to deodorise your carpet.

  • Step 3: Run a powerful vacuum cleaner over the carpet from at least two different directions.

The coffee ground smell will disappear gradually in a few days, leaving you with a fresh smelling carpet.

How To Get Milk Smell Out Of Carpet Using An Enzyme Spray - Remedy #5

  • Step 1: Spray an enzyme cleaning product liberally.

  • Step 2:  Let it set in for a couple of days, preferably two. Though, we advise you to follow the guidelines on the product label.

  • Step 3:   Blot the area dry.

  • Step 4:  Vacuum your carpet to straighten the fibres.

Enzyme cleaning products use proteins and enzymes that weaken and break down the structure of stains. They will eat away at the unpleasant smell residue. You can purchase the products from most local improvement stores or online marketplaces.

How To Remove Milk Smell From Carpet With Charcoal Bags- Remedy #6

  • Step 1:   Put the charcoal bags over the smelly part of your carpet.

  • Step 2:  Cover the spot using a terry towel.

  • Step 3:   Vacuum once the lingering nasty odours are gone.

Charcoal bags are highly effective at deodorising and absorbing foul odours from your carpet. Most of the charcoal bag varieties you will find on the market use bamboo charcoal. There are different sizes and shapes for every need.
