Having children is a delight and a joy, but it’s also messy and frustrating at times.

It seems like every load of laundry when you have small children has some urine stain on it, which is always a pain to remove.

Have you ever needed to know how to get urine stains out of underwear?

If this sounds like something you have dealt with, make sure to keep reading to find the most effective and efficient methods for getting urine stains out of underwear and keeping your clothes looking as good as new. 

What You’ll Need

Baking Soda

Baking soda is truly a miracle worker when it comes to removing stains.

Not only will it help lift the stain from the fabric, but it will also help remove any odor left behind by the stain.

It’s always good to keep baking soda on hand, and if you have kids, you need a lot.

Distilled white vinegar is a great cleaning tool for many different kinds of stains.

It is a great solution to keep around the house at all times, as you never know when you will need it.

I found this Goya White Vinegar brand on Amazon that gets great reviews and works really well.

Cold Water

Cold water will be necessary to soak and rinse the underwear during the cleaning process.

Do not use warm water as it will set the stain further into the fibers of the fabric, making the stain harder to remove. 


You can use any scrubber to clean the stain as long as it will not damage the fabric of the underwear.

A toothbrush, sponge, or rag would all be good choices to scrub the stain. 

Protective Gloves

Make sure to always protect yourself when working with bodily fluids and wear protective gloves.

These Cleanbear Synthetic Rubber cleaning gloves are a favorite of mine and get great reviews on Amazon.

Bleach ( In Extreme Cases)

Only in extreme cases where the urine stain has been on the underwear for some time and has been through the wash several times will bleach be used.

A strong bleach, such as Clorox Performance Bleach with Cloromax, should be used when this happens.

And that’s all you need.

Step By Step Instructions For How To Get Urine Stains Out Of Underwear

#1. Apply Baking Soda to the Stain

Urine stains are always easier to remove when they are fresh, so try to get to the stain as soon as possible.

Cover the stain in a thin layer of baking soda and let it sit for 10-15 minutes.

The baking soda should soak up a good amount of the urine.

Brush off the baking soda and repeat 2-3 times until it has all been soaked up.

Rinse the underwear in cool water to ensure that as much of the stain has been removed as possible.

It is important to use cool water for all of these steps to ensure that the stain doesn’t get pushed into the fabric, making it harder to remove. 

#2. Soak the Underwear in Cold Water

Once you have brushed off all of the baking soda and the stain has been soaked up, fill a sink or other basin with cool water and a cup of vinegar.

Soak the underwear in the water and vinegar mixture for up to an hour.

The vinegar will help break the stain down even further, and it should be completely removed by the time you take it out.

Scrub the stain under the cool water until you are sure it has been removed.

Rinse the underwear in more cool water and leave them out to dry.

Do not put them in the dryer just yet. 

#3. Wash the Underwear

After the underwear has dried and the stain has been completely removed, wash the underwear in the washer on a cold setting.

It is important to keep using cool water until you are certain the stain has been completely removed.

Once they are done being washed, leave them out to dry again.

Using the dryer at this point is not a good idea, as it can set the stain into the fabric without you even knowing it’s there. 

#4. Inspect & Repeat

Once the underwear has been completely dried, you can do a final inspection to make sure the urine stain has been removed from the fabric of the underwear.

If the stain is gone and the underwear looks and smells clean, they can be washed and dried like normal.

If the stain still remains, repeat the above steps as many times as necessary to make sure that the stain is completely gone.

If you have a stain that is proving harder to remove, you can use bleach on it, as long as the underwear is white.

Bleach will discolor anything other than white underwear.

In most cases, however, you will not need to worry about bleach as the vinegar, and baking soda will be more than enough to get the urine stain out of the underwear.
