How to Maintain Durable Medical Equipment: Expert Tips

April 2, 2026

Your durable medical equipment is more than a purchase, it’s something you rely on every single day. Whether it’s a wheelchair, hospital bed, CPAP machine, or walker, keeping that equipment in top shape directly affects your comfort, safety, and independence.

At MacPherson’s Medical Supply, we’ve spent over 80 years helping families across the Rio Grande Valley find the right medical supplies and keep them working like they should. We know that learning how to maintain durable medical equipment doesn’t have to be complicated. A few consistent habits can save you money, prevent breakdowns, and extend the life of the devices you depend on.

In this guide, we’ll walk you through practical, easy-to-follow care tips, from daily cleaning routines to knowing when it’s time for professional repair.

Why Proper DME Maintenance Matters for Safety and Longevity

Durable medical equipment is built to last, but “durable” doesn’t mean “indestructible.” Over time, parts wear down, surfaces collect bacteria, and small issues turn into bigger, and more expensive, problems. Regular maintenance keeps your equipment safe to use and functioning the way it was designed to.

For mobility devices like wheelchairs and scooters, neglected maintenance can lead to brake failures, flat tires, or electrical malfunctions. For respiratory equipment like oxygen concentrators and CPAP machines, dirty filters or worn tubing can reduce therapy effectiveness and even pose health risks.

There’s also a financial side to this. Well-maintained DME lasts significantly longer, which means fewer out-of-pocket replacements. And if your equipment is covered through Medicare or insurance, keeping it in good condition is often part of the agreement. Bottom line: a little routine care goes a long way toward protecting both your health and your investment.

Daily and Weekly Cleaning Best Practices

Cleaning is the simplest and most effective thing you can do to extend the life of your medical equipment. Here’s how to approach it based on the type of DME you use.

Daily Cleaning

Wheelchairs, walkers, and canes: Wipe down armrests, handles, and seats with a mild disinfectant or soap-and-water solution. These are high-touch surfaces that collect germs quickly.
CPAP masks: Rinse your mask cushion with warm water each morning after use. This removes facial oils and keeps the seal effective.
Hospital beds: Wipe side rails and controls daily, especially if multiple caregivers are assisting.

Weekly Cleaning

CPAP humidifier chambers: Soak in a mixture of warm water and white vinegar for about 30 minutes, then rinse thoroughly and air dry.
CPAP tubing: Submerge the tubing in warm, soapy water, swish gently, rinse thoroughly, and hang to air dry completely before next use. This prevents moisture buildup and microbial growth inside the tube.
Wheelchair frames and wheels: Use a damp cloth to remove dust and debris. Check caster wheels for hair or thread buildup, this is a surprisingly common issue that affects rolling performance.
Commodes and bath safety products: Disinfect all contact surfaces with a non-abrasive antibacterial cleaner.

One thing we always tell our customers: avoid harsh chemicals like bleach on most DME surfaces. They can degrade rubber seals, crack plastic components, and damage upholstery over time. When in doubt, check your equipment’s user manual or give us a call.

Routine Inspection and Preventive Maintenance Schedule

Beyond cleaning, you should build a habit of visually inspecting your equipment on a regular basis. Think of it like checking the oil in your car, catching a small problem early prevents a major headache later.

Monthly Checks

Tires and wheels: Look for cracks, low air pressure, or uneven wear on wheelchair and scooter tires.
Brakes and locks: Test that wheel locks engage fully and hold the device in place.
Batteries: For power wheelchairs and scooters, check that batteries hold a full charge. A noticeable drop in runtime often signals it’s time for a battery replacement.
CPAP filters: Disposable filters should be swapped monthly. Reusable ones need a thorough rinse and inspection.

Every 3–6 Months

Upholstery and cushions: Check for tears, sagging, or compressed foam. Seat cushions on wheelchairs are critical for pressure relief.
Electrical connections: On power mobility devices, inspect wiring and connectors for fraying or corrosion.
Oxygen equipment: If you use an oxygen concentrator, check the flow rate with a flow meter and ensure the unit isn’t overheating during use.

Keeping a simple log, even just notes on your phone, helps you track what’s been checked and when. It’s especially useful if you’re a caregiver managing equipment for a family member.

Storage and Environmental Care Tips

Here in South Texas, our climate can be tough on medical equipment. Heat, humidity, and dust are constant factors, especially during the long summer months in the Rio Grande Valley.

Store your DME in a clean, dry, temperature-controlled area whenever possible. Avoid leaving wheelchairs, scooters, or walkers in a hot garage or vehicle trunk for extended periods, extreme heat can warp plastics, degrade battery life, and weaken adhesives.

For CPAP machines and respiratory supplies, humidity is the bigger concern. Moist environments encourage mold growth inside tubing and humidifier chambers. Store these items in a well-ventilated room and make sure everything is completely dry before putting it away.

A few more quick tips:

Keep equipment off the floor when storing long-term to prevent moisture damage.
Cover unused devices with a breathable cloth or fitted cover to keep dust out.
Never store batteries fully discharged. Charge power wheelchair and scooter batteries to at least 50% before any storage period longer than a couple of weeks.

These small steps make a real difference in how long your equipment stays functional and safe.

When to Seek Professional Repair or Replacement

There comes a point where DIY maintenance isn’t enough. Knowing when to call in a professional can prevent injuries and save you from using equipment that’s no longer safe.

Seek professional help if you notice:

Unusual noises from power wheelchairs or scooters (grinding, clicking, or whining)
Inconsistent braking or steering that pulls to one side
Visible structural damage like bent frames, cracked welds, or broken footrests
Electrical issues such as intermittent power, unresponsive controls, or error codes
Reduced therapy effectiveness from respiratory equipment even though new filters and clean components
