A treadmill is one of the most reliable pieces of home cardio equipment you can own, but like anything mechanical, it performs best when it gets the right care. Looking after it properly keeps your workouts smooth, reduces unexpected issues and protects your investment for years to come. These treadmill maintenance tips are simple, beginner-friendly and suitable for both home users and small fitness spaces.
Clean the treadmill belt
Knowing how to clean a treadmill belt is essential because the belt is in constant contact with your shoes, sweat and dust. A dirty belt can slip, wear unevenly or put extra load on the motor.
Here’s a simple process that works for most treadmills, but it’s always best to check your user manual for any brand-specific instructions:
- Unplug the treadmill before you start.
- Wipe the belt surface with a mild, non-abrasive cleaner.
- Lift the belt slightly and clean underneath with a soft cloth.
- Allow it to dry completely before using the treadmill again.
Keeping the belt clean reduces friction, helps the deck last longer and ensures a smoother stride.
Keep the surface clean
Dust, sweat and small debris naturally build up on a treadmill over time. A quick wipe-down after every session goes a long way towards preventing grime from reaching the moving parts.
Use a damp cloth on the handrails, console and side areas. This small habit helps the equipment run smoothly and also keeps it hygienic. Regular cleaning is one of the simplest ways to extend the life of your treadmill without requiring extra tools or effort.
Check belt tension and alignment
A belt that is too tight can strain the motor. A belt that is too loose can slip, or “skip”, during use. Both situations reduce comfort and can shorten the equipment’s lifespan.
Every few weeks, walk slowly on your home treadmill and check whether the belt feels centred. If it drifts to one side or feels uneven, small adjustments with the rear bolts can bring it back into place.
Lubricate when needed
Many treadmills require lubrication to reduce friction between the belt and the deck. Always follow the guidance in your equipment manual. When lubrication is due, apply the recommended amount only. Too much lubricant can cause slipping, while too little increases wear. Proper lubrication significantly helps to extend the treadmill’s life by reducing strain on the motor and rollers.
Keep the area around your treadmill dust-free
Treadmills pull air in through the motor compartment. If the room is dusty, that dust often ends up inside the machine. A clean training space keeps the internal parts running more efficiently. Vacuum around and underneath the treadmill regularly and make sure nothing is blocking the air vents.
Protect the treadmill with a mat
A quality floor mat protects both your flooring and the treadmill. It absorbs vibration, catches debris and limits dust from reaching the motor. This is a small investment that supports long-term gym equipment care and helps make each run or walk feel steadier.
Be mindful of usage
If you use your treadmill daily, small checks become even more important. Listen for new noises that might indicate a loose bolt or worn part. Pay attention to changes in how the belt feels. The sooner you notice a shift in performance, the easier it is to fix.
Being proactive helps you stay ahead of issues and keeps your routine running without interruption. These small habits build a long-term approach that strengthens your ability to extend the treadmill’s life naturally.
Inspect cables, power points and safety keys
A treadmill relies on safe electrical connections. Check the power cable for signs of wear and make sure the cord is not bent sharply behind the machine. Test the safety key regularly so the emergency stop feature stays functional. These checks only take a few seconds but contribute significantly to overall safety.
When to call in professional help
Home maintenance covers the essentials, but a trained technician can check the internal parts you cannot access, such as the motor, rollers and electronics.
Professional servicing is especially useful if the treadmill is used daily, shared by multiple people or showing early signs of wear. If you notice any of the following, it is time to book a service:
- Unusual noises — Grinding, squeaking or rattling often indicate misaligned or worn components.
- Belt slipping or hesitation — A belt that slows, slips or feels uneven may need tensioning or roller adjustment.
- Overheating or unusual smells — A burning smell or excessive heat from the motor area should be assessed quickly.
- Speed inconsistencies — If the treadmill changes pace unexpectedly, the motor or control board may require attention.
- Visible wear on the belt or deck — Cracking, fraying or uneven patches suggest the belt or deck is wearing down and needs inspection.
- Recurring error codes — Console errors usually point to an internal issue that requires an expert to diagnose.
Calling a professional early protects your safety and helps extend the life of your treadmill by preventing minor issues from developing into major repairs.
