Preparation Parade

Before you dive into the cleaning process, it’s crucial to prepare your workspace and gather all necessary tools. First and foremost, unplug your treadmill.

This ensures your safety and protects the fitness equipment from potential electrical issues.

Gather your cleaning supplies: a vacuum, microfiber towels, a soft cloth, an appropriate cleaner or disinfectant, and the correct type of lubricant as recommended in your owner’s manual. 

If your treadmill is placed on a treadmill mat, it’s wise to remove it for thorough cleaning. This preparatory step sets the stage for an effective cleaning process.

Dust Busting

Now, it’s time to tackle the dust and debris. Start by using the vacuum around the treadmill, mainly focusing on areas prone to dust accumulation.

Pay close attention to the space around the motor, as an accumulation of dust can lead to overheating or malfunction. 

Carefully vacuum underneath the treadmill as well. If your vacuum comes with a hose attachment, use it to reach tight spaces.

This step is pivotal in preventing dust and debris from interfering with the treadmill’s functionality and ensuring a clean environment for your home gym.

Belt Basics

Engage in belt basics by first turning off the treadmill. Carefully clean your treadmill belt using a damp microfiber towel, ensuring you remove every speck of dust or debris.

Check the alignment of the belt; if it’s sliding or wiggling, it’s time to tighten it. Refer to your owner’s manual for guidance, and use an Allen wrench for adjustment.

This is a crucial step to maintain your treadmill and prevent any damage to the belt, ensuring your treadmill at home remains in top-notch condition.

Lubrication Station

Lubrication is key to maintaining the smooth operation of your treadmill. With the treadmill off, apply the recommended best treadmill lubricant under the belt. 

This step is essential to keep your treadmill belt clean and moving effortlessly. Ensure you rotate the belt manually to distribute the lubricant evenly.

Proper lubrication prevents friction and wear, extending the life of your treadmill and keeping it functioning like new.

Deck Duty

Now, let’s focus on deck duty. Thoroughly clean the belt and deck area of your treadmill. Use a microfiber towel to wipe down and remove any remaining dirt or dust.

It’s important to ensure no debris is left uncleaned, especially underneath the belt. This step is not just about cleanliness; it’s about maintenance and protecting your treadmill to keep it running smoothly.

Regular cleaning prevents build-up that can affect the treadmill’s performance and longevity, especially for a treadmill at home.

Disinfection Direction

Finally, it’s time for the disinfection direction. Using a soft cloth and a non-corrosive cleaner, gently disinfect the handles, display screen, and any other high-touch areas of your treadmill.

This step is essential to kill germs and maintain hygiene, especially if your treadmill is a key part of your home gym. Be thorough but gentle to avoid damaging any electronic components.

Regular disinfection is crucial, especially after every use, to ensure a clean and safe workout environment.

Final Flourish

Concluding the maintenance process, it’s time for the final flourish. Carefully plug your treadmill back in and turn it on. This step is vital to ensure everything functions correctly after cleaning and maintenance.

Observe the treadmill belt as it turns; it should move smoothly without wiggling or sliding. If the belt needs further adjustments, use an Allen wrench to tighten or loosen the bolts as required. 

This step is particularly important for a treadmill at home, where professional maintenance may not be readily available.

Ensure the belt is properly aligned and running smoothly to conclude your comprehensive treadmill maintenance and cleaning routine.

Key Considerations For Successfully Maintaining Your Treadmill

While the step-by-step guide provides a thorough understanding of how to keep your treadmill clean and in good working condition, there are additional considerations to ensure long-term success.

Firstly, always check your owner’s manual for specific guidelines related to your treadmill model. This is crucial as different models may have unique requirements for maintenance and cleaning.

Additionally, it’s essential to regularly inspect your treadmill for signs of wear or damage, especially if you’re using your treadmill frequently in your home gym. This proactive approach can help prevent potential issues before they escalate.

Another critical consideration is the placement of your treadmill. Ideally, it should be on a mat to minimize the accumulation of dust and dirt underneath. This also helps in preserving the surrounding area and flooring.

Remember, maintaining your treadmill isn’t just about cleaning; it’s also about ensuring it’s positioned and operated in a way that minimizes the risk of damage.

Taking it to the Next Level: How to Enhance Your Treadmill’s Performance and Longevity

To go beyond basic cleaning and maintenance, consider incorporating a regular schedule for deeper cleaning.

This includes removing the motor cover and carefully vacuuming the area to remove any accumulated dust. Additionally, rotating the belt periodically ensures even wear, extending its life.

Enhancing your treadmill’s performance also involves paying attention to the details. For instance, using the hose attachment of your vacuum to clean around the display and control buttons can prevent the buildup of grime that could potentially interfere with the electronics.

When disinfecting, use a soft towel and slide it gently in a circular motion to avoid damaging sensitive areas.

To elevate your treadmill care, it’s also essential to recognize the signs when professional maintenance is needed. If you notice any unusual noises, belt slips, or other irregularities that persist even after your maintenance routine, it may be time to consult a professional. 

Keeping your treadmill in a like-new condition not only enhances your workout experience but also ensures the longevity and reliability of your equipment.

Alternatives to Traditional Treadmill Maintenance

If maintaining your treadmill seems daunting or time-consuming, there are alternatives to consider. One option is to invest in professional cleaning and maintenance services.

Many gym equipment providers offer maintenance packages where experts handle everything from belt adjustments to deep cleaning. This is especially useful for those with a treadmill at home but lack the time or expertise for detailed maintenance.

Another alternative is to opt for treadmills that require minimal maintenance, like high-quality treadmill desks. Some newer models are designed with advanced materials and technology that reduce the need for frequent cleaning and lubrication. 

While these might be more expensive upfront, they can save time and effort in the long run. For those who use treadmills sporadically, portable or compact treadmills might be a viable option. These tend to have simpler mechanisms and are easier to clean and maintain.


Maintaining a treadmill can be a straightforward process with the right steps and considerations. However, for those seeking alternatives, options range from professional services to choosing low-maintenance models.

Regardless of your chosen method, the goal remains the same: to ensure your treadmill remains a reliable and efficient part of your fitness routine. For those constantly on the move or with limited space, an excellent alternative to consider is an under-desk treadmill. 

These compact and portable devices are perfect for staying active while working or traveling. Check out the top under desk Treadmills for travel to find the perfect balance between convenience, fitness, and mobility.


My treadmill belt got dirty, how do I clean it?

Well, first things first, you’ll need to turn off the treadmill and unplug it.

You wouldn’t want to have it randomly decide to turn on and give an impromptu run while you’re working on it, right?

Use a slightly damp, not soaking, cloth to wipe down the belt. Remember, the treadmill is one of your buddies.

Don’t drown it! For stubborn dirt, you may need to loosen the belt slightly and clean underneath it using a soft brush.

The treadmill is acting funny; one side of the belt seems to be looser than the other. What should I do?

When your treadmill gets moody, it’s likely due to an unaligned belt, or simply it just needs some affection.

Tighten the belt by adjusting the bolts on the back of the treadmill. Don’t forget, righty-tighty, lefty-loosey!

Well, unless you’re facing the bolt, then you should go clockwise to tighten. Just make sure you get the belt back where it needs to be.

Is it necessary to clean underneath the treadmill?

Yes, sweetheart. Like any other naughty hiding spot, dust and much dirt love to hang out under your home treadmill.

In addition to stretching the longevity of your machine, you’ll also do your air quality a favor!

One more thing: it’s recommended to place a mat underneath your treadmill. It’ll help to catch any little dirt particles that want to play hide-and-seek.

Why is my treadmill belt not turning?

Ooh, the silent treatment, eh? In most cases, if the belt isn’t moving, you’ll need to tighten it.

However, if it still doesn’t want to cooperate, take a peek at the motor or the belt itself. If the motor is corroded, rust might be the villain here.

It’s time to call an exorcist… or maybe just a maintenance guy would do the trick.

How do I keep the belt going smoothly?

Regular treadmill maintenance can indeed help keep your belt going and your run smooth.

This can be done using a treadmill lubricant. But remember, just like salt in your soup, you’ll want it in just the right amount.

Apply it between the belt and the deck, and let that baby glide!

How can I prevent my treadmill from getting dirty?

Well, unless you plan on running in a complete biodome, it’s going to get dirty.

But hey, a little dust never stopped a great workout! You can use a cover after each use to obstruct those pesky dust particles.

How do I clean the display and other parts of the treadmill?

Cleaning the display and buttons can be done using a good old microfiber cloth and a little mild cleaning solution.

Please, don’t go all Niagara Falls on it; a little will do. And hey, there are no paper towels on the display; it could scratch!

What should I do if the screws of my treadmill start to corrode?

In case of corrosion, you’ll need to remove the screws and replace them.

But let’s try to avoid this, okay? You might make the treadmill feel self-conscious about its body parts.

Regular cleaning and timely maintenance will typically prevent this issue. Plus, everyone loves a little TLC!

Should I loosen the belt before cleaning underneath it?

Well, risking to sound like your mom here, but it’s also important to move the belt to one side to clean underneath it.

Loosening could help, but don’t make it too loose! Remember the rule: Loosen enough to clean, then tighten enough to run!

When should I replace my treadmill’s belt?

It’s like changing the tires on your car; when they start looking too worn out, it’s time for a change.

Deep cracks, frays, or any damage can affect the performance of your treadmill. Not to mention, running on a damaged belt can feel like running on Grandma’s old braided rug, not fun!
