The scientific reason behind your bad smelling activewear and easy DIY solutions

Why does your activewear stink and what can you do about it?

Life

Do you ever take your laundry out of the dryer and realize that your activewear still smells bad? Sometimes it feels like no amount of laundry detergent or scented fabric softener will get rid of that funky smell that lingers in all of your workout clothes. The reason this happens isn't because your washing machine isn't strong enough to get rid of the sweat from your run or all the burpees you did, but it's actually the fabric. Most workout clothes are made from synthetic fabrics or cotton, two materials that are great for working out in, but really bad at getting clean. Luckily there are a few ways to get rid of that smell that doesn't involve lots of harmful chemicals. So instead of throwing those smelly clothes away, check out some of our easy non-toxic cleaning methods and DIY solutions!

Why do workout clothes trap smell?

Most people think that the reason their workout clothes stink is because there is sweat trapped in them, but that is only partially true. Sweat by itself actually has no smell at all, but when it comes into contact with the bacteria on your skin, the sweat gets broken down and releases the typical body odor smell (1). So that means there isn't excess sweat trapped in your clothes, it's bacteria, along with dead skin cells and natural particles that are all contributing to the bad smell (2).

There is also a difference in how natural and synthetic workout clothes are affected by this bacteria. Natural fibers like cotton are more affected by sweat and bacteria compared to synthetic fibers because the bacteria that becomes trapped within the fabric can actually start to break down and degrade your clothes. The fibers of cotton are made completely of cellulose, a natural component of plants, and the bacteria can consume this substance and break down the clothes. Cotton is really good at absorbing sweat, so that means there is bacteria deep inside the cotton fibers and the bacteria can quickly multiply due to their massive food source i.e. your clothes. So not only will the bacteria in your sweat make your natural workout clothes smell bad, it will also degrade them over time until they fall apart (2).

Synthetic fabrics, on the other hand, are man-made fibers that are derived from petroleum products. Think plastic threads. Fabrics like spandex, polyester, and nylon are all made of synthetic materials and they are often marketed as sweat wicking or having a cooling effect. These types of fabrics collect bacteria in the space between the fibers, but does not absorb the sweat or bacteria in the fibers. These small spaces where the bacteria are trapped are really hard to access with standard cleaning products making the smell linger (2).

What makes it worse?

To get rid of the smell a lot of people use more detergent or heavily scented fabric softeners, but this only temporarily covers up the smell. These products coat the fibers and fill up the space between them, creating more and more build up the more you wash the clothes. Having build up on your clothes can trap the bacteria and every time you work out more bacteria will start to grow on your clothes.

Traditional detergents were made for traditional fibers like cotton, so when trying to get spandex or polyester fabrics clean, these detergents often aren't strong enough to penetrate deep into the synthetic fabric. Also sometimes your washing machine might be too big or too full and isn't able to clean the clothes effectively. The good news is that there are some non-toxic products and DIY methods that will really deep clean your clothes and make them smell brand new!

What can you do?

First things first, before you get into the products and DIY solutions, try some of these simple ways to avoid having stinky workout clothes in the first place. Sometimes all it takes is changing the temperature or washing your clothes a little sooner. But if none of these work, check out the special products and DIY solutions that are sure to get your clothes squeaky clean!

How to Naturally Deep Clean Your Laundry Machine

Non-toxic cleaning methods for different types of washing machines

Have you been noticing that your clothes smell a little funny or there is a bad smell coming from your laundry room? Or maybe there are some green spots around the door of your washing machine? Well it might be time to clean your washing machine! If you search up conventional ways of cleaning your washing machine, many times those methods call for bleach and other harsh chemicals that can cause harm to our environment and our health. Instead of using harsh chemicals to clean your washing machine, try out a few of the methods we recommend that use safe and natural cleaners!

Three ways to clean your washing machine

1. Vinegar and baking soda

Vinegar is a strong acid that works really well to dissolve mineral deposits, dirt, grease, grime, and can even kill bacteria. And baking soda is a great deodorizer and works as a gentile abrasive to help get rid of hard water grime.

Top loader:

  1. Turn your washing machine to the hottest and longest cycle. Then add four cups of distilled white vinegar and let the cycle run for about a minute.
  2. After a minute or until the vinegar is mixed with the water, stop the cycle and let the water sit for about an hour.
  3. While you wait, it's time to tackle the rest of the washing machine. Take a cloth and some vinegar and wipe down the lid and the outside of the washer.
  4. It's also a good time to clean the seal if your top loader has one. Take some straight vinegar and pour it directly into the seal and scrub until all the mold or mildew comes out. For some extra disinfection and a great smell, you can mix 10 drops of an essential oil, like lemon or eucalyptus, with the vinegar to clean the seal.
  5. Once that first cycle is completely over, restart the cycle and pour a cup of baking soda into the drum. Once the second cycle is complete leave the lid open to completely dry the drum (1).

Front loader:

  1. Start by cleaning the seal using straight white vinegar. Feel free to add drops of essential oils like lemon or eucalyptus oil for a great smell and some added disinfection.
  2. Scrub all of the mold, soap scum, and possibly hair out of that seal. Make sure you pull it all the way back so you can clean every inch!
  3. Start your hottest cycle and then pour 2 cups of vinegar into the detergent dispenser.
  4. Once that cycle is finished start another cycle by putting ½ cup of baking soda in the drum and running the same hot water cycle.
  5. Finally wash the outside of the washing machine with vinegar and a cloth and use vinegar to scrub and clean out the detergent tray (1).
  6. Leave the door open to let the drum fully dry out.

If you are concerned that vinegar can damage the seal of your washing machine, you can either dilute the vinegar or completely rinse off the seal with a wet cloth to avoid any potential corrosion. If you are still not sure about using vinegar, check out one of the other methods we recommend!

2. Non chlorinated bleach

Non-chlorinated bleach is a much safer alternative to the traditional bleach. It doesn't contain chlorine which can irritate the skin, eyes, and lungs (5). This type of bleach is still a great disinfectant so this might be a great solution if your washer has a lot of mold or mildew buildup. We love the brand seventh generation non-chlorine bleach!

Top loader:

  1. Select the hottest and longest cycle and pour ¾ cup of non-chlorinated bleach into the drum and run the cycle for one minute. Open the lid to let the water/bleach sit in the drum for about an hour. Then complete the cycle.
  2. Clean the outside of the machine using a mixture of water and bleach or a non-toxic all purpose cleaner and use a cloth to wipe down the outside.
  3. If your top loader has a seal, pour a small amount of the non-chlorinated bleach and scrub all of the gunk out and make sure to wipe it out until it's dry (2).
  4. Leave the lid open to let the drum fully dry out.

Front loader:

  1. To clean the door seal, pour some bleach straight on the seal and scrub all of the mold and stains off. Pull the seal all the way back to get all of the gunk out!
  2. Using a mixture of water and bleach or an non-toxic all purpose cleaner, use a cloth to wipe down the outside and also scrub out the detergent tray to get rid of all of the residue and mold.
  3. Next select the hottest and longest cycle and pour ¾ cup of non-chlorinated bleach into the detergent tray and run the cycle (2).
  4. Leave the door open to let the drum fully dry out.

3. Washing soda

Washing soda is a popular cleaning additive that is great for removing stains, dissolving grease, softening water, and getting rid of unpleasant smells. It's definitely worth picking some of this up! We love the brand Arm & Hammer Super Washing Soda!

For both washer types:

  1. Dissolve some washing soda in some hot water and scrub the seal if you have one. If you have a really dirty seal, try using one of the other methods after you scrub and rinse off the washing soda, which helps to loosen some of the grime..
  2. Select the hottest and longest cycle and pour 2 cups of washing soda into the drum and run the cycle.
  3. Make sure to clean the rest of the washing machine by dissolving some washing soda in water and wiping it down with a cloth (3).

Tips for keeping a clean washing machine

  1. Keep the lids/doors open always so the moisture can dry.
  2. After the seal is cleaned, you can help prevent mold growth by wiping the seal down with a non-toxic all purpose cleaner weekly. This will prevent mold and grime from building up!
  3. To clean a fabric softener dispenser, pour boiling water on it and scrub until all of the built up residue is gone. For a non-toxic fabric softener option, check out some of the brands we recommend!
  4. Switching to powdered laundry detergent has been known to reduce the smell coming for your laundry machine. Bonus, powdered laundry detergent does not contain preservatives like liquid laundry detergent. Check out some of the brands we recommend!
