Keeping your underwear clean is crucial for hygiene and extending the life of these essential garments. Fortunately, washing underwear doesn’t have to be a complicated process. Whether you prefer the gentle touch of hand washing or the convenience of a machine, understanding the right techniques will ensure your delicates remain fresh and in good condition.
This guide will walk you through simple yet effective steps for both hand washing and machine washing your underwear. We’ll cover everything from sorting and choosing the right detergent to drying methods that prevent damage, empowering you to care for your undergarments with confidence.
Should You Wash Underwear Before Wearing
Yes, it is highly recommended that you wash underwear before wearing it for the first time. During the manufacturing, shipping, and handling processes, underwear can come into contact with various substances, including dyes, chemicals used in production, dust, and microbes from multiple handlers. Washing removes these potential irritants and ensures the garment is clean and safe to wear against your skin.
Wearing unwashed underwear can potentially lead to skin irritation, allergic reactions, or even minor infections due to the presence of these residual substances. Laundering new underwear, even if it appears clean, is a simple yet crucial step in maintaining personal hygiene and preventing potential health issues. Think of it as a necessary first step to ensure the garment is truly clean and ready for comfortable and safe wear.
Here are some reasons why washing new underwear is important:
- Removes manufacturing residues: Dyes and chemicals used in production can irritate sensitive skin.
- Eliminates dust and dirt: Garments accumulate dust and dirt during storage and transportation.
- Reduces the risk of infection: Washing helps remove any potential bacteria or germs picked up during handling.
- Ensures personal hygiene: It’s a basic step to ensure the garment is clean before direct skin contact.
How to Hand Wash Underwear

For delicate fabrics or to extend the life of your favorite pairs, hand washing underwear offers a gentle yet effective cleaning method. This approach provides more control over the process, minimizing the risk of damage that machine washing can sometimes cause. Taking a few extra minutes for hand washing can make a significant difference in the longevity and care of your undergarments. Let’s explore the steps involved.
Tools Needed
To hand wash your underwear, you will need a few basic items:
- A clean basin or sink.
- Mild detergent specifically designed for delicates or gentle fabrics.
- Cool or lukewarm water.
- A clean towel.
Step 1: Prepare the Wash Basin
Begin by ensuring your basin or sink is thoroughly clean to avoid transferring any dirt or residue to your delicate items. Fill it with cool or lukewarm water. It’s important to avoid hot water, as this can damage elastic fibers and cause colors to fade or bleed, especially in delicate materials like lace or silk commonly found in underwear.
Once the basin is filled, add a small amount of mild detergent. Look for detergents specifically labeled for delicates or gentle washing, as these are less harsh than standard laundry detergents. Gently swish the water with your hand to ensure the detergent is evenly distributed and creates a light, soapy solution. Avoid using excessive detergent, as it can be difficult to rinse out completely and may leave residue on the fabric.
Step 2: Submerge and Soak
Carefully place your underwear into the soapy water, ensuring they are fully submerged. Avoid overcrowding the basin; wash only a few items at a time to allow for thorough cleaning and rinsing. Gently press down on the underwear to release any trapped air and ensure the water penetrates the fabric fibers.
Allow the underwear to soak for about 15 to 30 minutes. This soaking time allows the detergent to gently lift dirt, oils, and other impurities from the fabric without the need for harsh scrubbing. For heavily soiled items, you can extend the soaking time slightly, but avoid soaking for more than an hour, as the released dirt can redeposit onto the fabric.
Step 3: Gently Wash and Rinse
After soaking, gently agitate each piece of underwear in the water. Use your hands to lightly massage the fabric, paying extra attention to areas that tend to accumulate more dirt, such as the crotch area. Avoid harsh scrubbing or twisting, as this can damage the delicate fibers and elastic.
Once you’ve gently washed each item, drain the soapy water from the basin. Refill it with clean, cool water for rinsing. Gently squeeze and rinse each piece of underwear under the running water until all traces of detergent are gone and the water runs clear. Repeat the rinsing process as needed to ensure no soapy residue remains, as this can cause skin irritation.
Step 4: Gently Dry
Once thoroughly rinsed, carefully remove the underwear from the basin. Gently squeeze out the excess water, being careful not to twist or wring the fabric, as this can damage the fibers and distort the shape. For delicate items, you can gently roll them in a clean towel to absorb more moisture.
Lay the underwear flat to air dry on a clean, dry surface or a drying rack, away from direct sunlight or heat. Avoid using a machine dryer for delicate underwear, as the high heat can damage elastic, lace, and other delicate materials, leading to loss of shape and reduced lifespan. Allowing them to air dry preserves their integrity and extends their usability.
How to Wash Underwear in Washing Machine

For convenience and efficiency, washing underwear in a washing machine is a common practice. However, to protect the delicate fabrics and ensure proper cleaning, it’s essential to follow specific steps and use appropriate settings. By taking a few precautions, you can effectively clean your underwear while maintaining their quality and longevity. Let’s explore the right way to machine wash your undergarments.
Tools Needed
To wash your underwear in a washing machine, you will need the following:
- A washing machine.
- Laundry detergent suitable for delicates or the fabric type of your underwear.
- A mesh lingerie bag (highly recommended).
Step 1: Sort Your Underwear
Before loading your washing machine, take a moment to sort your underwear by color and fabric type. Separate whites from colors to prevent dye transfer, especially during the initial washes. Additionally, consider separating delicate items like lace or silk from more durable cotton or synthetic blends. This sorting ensures each type of fabric receives appropriate care during the wash cycle.
Treating different colors separately is crucial for maintaining the vibrancy of your garments and preventing unwanted discoloration. Similarly, different fabric types may require different wash cycles and temperatures. Delicates, for instance, benefit from a gentler cycle, while sturdier fabrics can typically withstand a more robust wash. Sorting helps optimize the cleaning process for each load.
Step 2: Use a Mesh Lingerie Bag
Placing your underwear inside a mesh lingerie bag is a highly recommended step when machine washing. This bag acts as a protective barrier, preventing your delicate items from getting snagged, stretched, or tangled with other heavier garments in the wash. It helps maintain the shape and integrity of the elastic, lace, and other intricate details of your underwear.
Using a mesh bag is particularly important for underwire bras and delicate fabrics. The tumbling action of the washing machine can be quite rough, and without the protection of a mesh bag, straps can get twisted, hooks can catch on other items, and delicate fabrics can tear. Investing in a few mesh bags is a small step that can significantly extend the life of your lingerie and underwear.
Step 3: Select the Right Wash Cycle and Temperature
When washing underwear, it’s generally best to choose a gentle or delicate wash cycle on your machine. These cycles have a slower agitation speed, which is less harsh on delicate fabrics and helps prevent damage. Avoid using heavy-duty or regular cycles, as these can be too rough for undergarments, leading to stretching, fading, and premature wear.
For water temperature, cool or lukewarm water is usually the safest option for washing underwear. Hot water can cause colors to fade, elastic to break down, and some fabrics to shrink. Cool water is effective at cleaning most everyday soil and is gentler on the fibers, helping to maintain the shape and elasticity of your undergarments over time.
Step 4: Use a Gentle Detergent
Select a mild laundry detergent that is suitable for delicates or the specific fabric of your underwear. Harsh chemicals and strong enzymes found in some regular detergents can damage delicate fibers and cause irritation. Opt for a gentle formula that will effectively clean without being too abrasive.
Avoid using bleach on your underwear unless the care label specifically recommends it for whites. Bleach can weaken the elastic and damage the fibers, leading to premature wear and loss of shape. If you need to brighten whites, consider using a color-safe brightener instead. Using the right detergent is crucial for maintaining the quality and longevity of your undergarments.
Step 5: Dry Your Underwear Properly
Once the wash cycle is complete, remove your underwear from the washing machine and the mesh bag. The best way to dry most underwear is to air dry them. Lay them flat on a clean, dry surface or hang them on a drying rack away from direct sunlight or heat.
Avoid using a machine dryer for your underwear, especially delicate items containing elastic, lace, or synthetic fibers. The high heat of a dryer can cause these materials to break down, leading to loss of elasticity, shrinkage, and damage to delicate embellishments. Air drying is a gentler method that helps preserve the shape and integrity of your undergarments, extending their lifespan.
How Do You Wash Period Underwear

Dealing with period underwear might seem a little different at first, but trust me, it’s super manageable and a great eco-friendly option. Let’s walk through the simple steps to keep them fresh and ready for your next cycle.
Rinse Immediately
As soon as you take off your period underwear, give them a good rinse under cold water. This is a crucial first step because cold water helps to prevent the blood from setting into the fabric, making it much easier to wash later. Continue rinsing until the water runs clear. Don’t worry about getting every single bit out at this stage; the goal is simply to remove the majority of the menstrual fluid.
Pretreat Stains (Optional)
If you notice any lingering stains after rinsing, you can pretreat them with a mild stain remover or even a bit of gentle laundry detergent. Apply a small amount directly to the stained area and gently rub it in with your fingers or a soft brush. Let it sit for about 15-30 minutes before proceeding with the main wash. This step can significantly improve the cleanliness of your period underwear, especially for heavier flow days.
Wash with Like Colors
Now it’s time for the main wash. You can either hand wash your period underwear or add them to a regular load of laundry with similar colors. If machine washing, it’s best to use a gentle cycle and avoid harsh chemicals like bleach or fabric softeners, as these can damage the absorbent layers of the underwear. If hand washing, use cool or lukewarm water and a mild detergent, gently massaging the fabric to remove any remaining residue.
Air Dry Completely
Once washed, the best way to dry your period underwear is by air drying them completely. Avoid putting them in the dryer, as the high heat can break down the absorbent materials and potentially damage the leak-proof layer. Simply lay them flat or hang them up to dry in a well-ventilated area. Ensure they are fully dry before storing them to prevent any mildew or odor buildup.
Is It Hygienic to Wash Underwear in Washing Machine

Yes, it is generally hygienic to wash underwear in a washing machine when done correctly. Modern washing machines and detergents are effective at removing dirt, bacteria, and other microorganisms from clothing, including underwear. However, there are a few key considerations to ensure a hygienic wash. Using the appropriate water temperature and a quality detergent are crucial for killing germs and ensuring cleanliness.
For heavily soiled underwear or in situations where hygiene is a significant concern, washing at a higher temperature (around 60°C or 140°F) is recommended to kill more bacteria. However, for everyday washing, a lower temperature (30-40°C or 86-104°F) with a good detergent is usually sufficient for cleanliness.
It’s also advisable to use a mesh lingerie bag to protect delicate underwear and prevent the spread of any potential contaminants to other items in the wash. Regularly cleaning your washing machine itself is also important for maintaining hygiene.
Here are some tips for hygienically washing underwear in a washing machine:
- Use a good quality detergent: Effective detergents help lift and remove dirt and microorganisms.
- Wash at the appropriate temperature: Higher temperatures are more effective at killing germs, but follow the care label.
- Use a mesh bag: This protects delicates and contains underwear separately.
- Don’t overload the machine: Ensure enough space for proper agitation and rinsing.
- Consider washing heavily soiled items separately: This prevents cross-contamination.
- Clean your washing machine regularly: This prevents the buildup of bacteria and mold.
Can You Put Period Underwear in the Washing Machine
Yes, you can absolutely put period underwear in the washing machine, and it’s generally the recommended way to clean them for thoroughness. However, there are a few important steps to take beforehand to ensure the best results and prolong the life of your period underwear.
Before machine washing, it’s crucial to rinse your period underwear in cold water until the water runs clear. This helps to remove the majority of the menstrual fluid and prevents staining. After rinsing, you can then place them in the washing machine with your regular laundry, ideally in a mesh lingerie bag for added protection. Always use a cold water cycle and avoid fabric softeners and bleach, as these can damage the absorbent layers and materials of the underwear.
Here’s a quick rundown of the steps:
- Rinse in cold water: Immediately after use, rinse until the water runs clear.
- Use a mesh bag: Place the rinsed underwear in a mesh lingerie bag for machine washing.
- Wash on a cold cycle: Use cold water to prevent setting stains.
- Use a mild detergent: Avoid harsh chemicals and bleach.
- Skip fabric softener: It can reduce the absorbency of the underwear.
- Air dry: Hang or lay flat to dry; avoid using a machine dryer as high heat can damage the fabric and layers.
Should Underwear Be Washed Separately
Yes, you should wash your underwear separately. While it might seem like an extra step, washing underwear separately from the rest of your clothes is often recommended for a few key reasons, primarily hygiene. Underwear comes into direct contact with your intimate areas, which can harbor bacteria, yeast, and other microorganisms. Washing them on their own helps prevent the transfer of these germs to your other garments, like your tops, pants, and towels, thus contributing to better overall hygiene.
Beyond hygiene, washing underwear separately can also help to prolong their lifespan. The delicate fabrics and elastic in underwear can be damaged by the harsher cycles and heavier fabrics in a typical mixed load. Separating them allows you to use a gentler wash cycle and avoid potential snags or stretching caused by zippers, buttons, or rougher materials. Here are some additional points to consider:
- Reduced Risk of Cross-Contamination: Minimizes the spread of bacteria and potential infections.
- Gentler Treatment: Preserves the elasticity and fabric of delicate undergarments.
- Avoidance of Harsh Chemicals: Allows for the use of milder detergents if preferred for sensitive skin.
- Prevention of Snags and Damage: Protects delicate items from being damaged by other clothing.
- Better Overall Cleanliness: Ensures underwear is thoroughly cleaned without being weighed down by heavier items.
Should Underwear Be Washed in Hot Water
While hot water is often associated with superior cleaning and germ-killing, it’s generally not the best choice for washing most underwear. The high temperatures can actually damage the delicate fabrics and elastic that are commonly used in undergarments, leading to premature wear and tear, loss of shape, and reduced elasticity.
Additionally, hot water can cause colors to fade and may even lead to shrinkage, especially in natural fibers like cotton.
For the majority of underwear, a cold or lukewarm wash is perfectly sufficient and much gentler on the materials. Modern detergents are formulated to clean effectively in cooler temperatures, and unless your underwear is heavily soiled or you’re dealing with a specific infection, hot water is usually unnecessary. Following the care label on your underwear is always the best practice to ensure its longevity and maintain its quality.
How Often Do You Wash Underwear
It’s generally recommended to wash your underwear after every single wear. This is a crucial hygiene practice because underwear comes into direct contact with your skin in a sensitive area that can harbor bacteria, sweat, and other bodily fluids. Re-wearing underwear, even for a short period, can increase the risk of odor, skin irritation, and potential infections as bacteria can multiply quickly.
Think of it this way: just like you wouldn’t re-wear socks or workout clothes without washing them, the same principle applies to underwear. Washing after each use ensures that you’re always putting on a clean garment, promoting better personal hygiene and reducing the likelihood of any unwanted issues. Here are some key reasons why daily washing is important:
- Hygiene: Removes bacteria, sweat, dead skin cells, and other bodily fluids.
- Odor Prevention: Prevents the buildup of unpleasant smells caused by bacteria.
- Reduced Risk of Infections: Minimizes the chance of skin infections or irritations.
- Overall Cleanliness: Ensures you feel fresh and comfortable throughout the day.
- Fabric Integrity: While washing is necessary, changing them daily prevents prolonged exposure to moisture and potential damage over time from accumulated substances.
