How to Clean Your EMSlim, EMSzero & HIEMT Handles: A Complete Guide
How to Clean Your EMSlim, EMSzero & HIEMT Handles: A Complete Guide
Clean handles after every client and deep clean them once a week. That simple routine keeps your EMSlim, EMSzero or HIEMT device hygienic, protects the electronics inside, and makes every treatment feel professional.
The handles (applicators) are the only part of your machine that touches skin. They pick up sweat, body oil, lotion and RF gel all day long. Left on the surface, that residue can irritate skin, spread bacteria between clients, and slowly work its way into seams and vents where it can damage the coil.
The good news: it takes about two minutes per handle. Here at Wikbeauty, this is the routine we recommend to every salon and clinic owner. Not sure which machine type you have? Our EMSlim vs EMSzero vs HIEMT comparison explains the differences.
What you need
You don't need anything special. Keep these at your treatment station:
| Item | What it's for |
|---|---|
| Soft, lint-free microfiber cloths | Wiping off gel and residue, drying |
| 75% isopropyl alcohol wipes (or a non-corrosive, alcohol-based medical surface disinfectant) | Disinfecting the treatment surface and grip |
| Paper towels | Removing excess RF gel first |
| Cotton swabs | Seams, button edges and around the cable joint |
| Warm water + a drop of mild, pH-neutral soap | Washing fabric straps and belts |
| Disposable gloves | Hygiene while cleaning |
Avoid bleach, acetone, abrasive powders and scouring pads. They can crack the plastic housing, fade markings and strip coatings off RF electrodes.
Step by step: after every client
- Stop and power down. End the program, switch the machine off and unplug it. Never clean a handle while it is live.
- Let it cool. HIEMT coils warm up during a 30-minute session. Wait a few minutes until the handle feels cool to the touch.
- Remove straps and wipe off gel. Unbuckle the fixing belt. Use a paper towel to remove all RF gel or lotion from the treatment surface.
- Wipe with a damp cloth. Lightly dampen a microfiber cloth with water (wrung out, never dripping). Wipe the treatment face, the sides and the grip.
- Disinfect. Wipe all surfaces with a 75% alcohol wipe. Pay attention to the treatment face, the start/pause button and anywhere hands touch.
- Clean the details. Run a cotton swab, barely dampened with alcohol, along seams, around buttons and where the cable joins the handle.
- Dry completely. Buff with a clean, dry cloth. Let the handle air-dry for 2 to 3 minutes before the next client.
- Store it properly. Rest the handle in its holder, treatment face up and clean. Don't let the cable hang, twist or get pinched.
EMSzero pelvic seat: wipe the seat cushion the same way after every client. Use a disposable cover or a fresh towel between client and seat.
Once the handle is clean and dry, it's ready for the next client. See our guide to optimal handle placement for target muscles and applicator positioning on curved areas.
Weekly deep clean
Once a week, with the machine off and unplugged, go a step further:
- Cables: wipe each handle cable from end to end with a damp cloth, then an alcohol wipe. Check for cracks, kinks or exposed wire. Stop using a damaged cable and contact your supplier.
- Connectors: unplug the handles (if your model allows it) and look at the plugs. Remove dust with a dry, soft brush or a puff of air. Never put liquid on connector pins.
- Cooling vents: most HIEMT handles are air-cooled. Clear dust from the vents with a dry brush so the fan can keep the coil cool. Blocked vents cause overheating and shorter handle life. Learn more about how cooling design affects your appointment schedule.
- Water-cooled models: if your machine has a water tank, follow the manual for changing the water. Use distilled water only, never tap water.
- Straps and belts: hand-wash in warm, soapy water, rinse and air-dry completely before use.
- Machine body and screen: wipe with a lightly damp cloth. Spray cleaner onto the cloth, never onto the screen.
While you're at it, do a quick safety check: housing free of cracks, buttons respond, no unusual smell or noise during a test run. If you imported your machine, also confirm your power supply matches its rating. Here's how to read voltage and frequency on imported machines.
Do's and don'ts
| Do | Don't |
|---|---|
| Unplug the machine before cleaning | Clean a handle that is switched on or still hot |
| Use a damp, well-wrung cloth | Soak, rinse or submerge a handle in water |
| Put cleaner on the cloth first | Spray liquid directly onto handles, vents or connectors |
| Use 75% alcohol or a mild medical disinfectant | Use bleach, acetone or abrasive cleaners |
| Dry fully before the next client | Store handles damp or wrapped in a wet towel |
| Coil cables loosely | Wrap cables tightly around the handle or pull on them |
| Keep a cleaning log for each handle | Skip cleaning on busy days |
The most common mistake is spraying disinfectant straight onto the handle. Liquid runs into seams and vents and can short the electronics, which is usually not covered by warranty. Read what our HIEMT machine warranty covers for the console and handles.
FAQ
Can I use hand sanitizer gel to clean the handles?
No. Gel sanitizers leave a sticky film and often contain thickeners and fragrance. Use alcohol wipes or a surface disinfectant instead.
Can I wash the handle under the tap?
No. EMSlim, EMSzero and HIEMT handles contain a magnetic coil and electronics. They are not waterproof. Wipe them only.
How often should I replace the fixing straps?
Replace them when the elastic loosens, the Velcro stops gripping, or the fabric stays stained after washing. Busy clinics often keep a spare set so one can dry while the other is in use, especially when running two clients at once on a 4-handle EMSlim.
The handle feels hot or shuts off mid-session. Is it dirty?
It can be. Dust in the cooling vents makes handles overheat. Clean the vents first. Short, planned pauses are normal, though. See machine pauses in treatment cycles: what to expect. If it keeps shutting off, stop using it and contact your supplier.
Do RF handles need extra care?
Yes. Remove all RF gel after each session, because dried gel builds up on the electrode surface and can affect heat delivery.
Keep your device working like new
A clean handle is a safe handle, and a well-kept machine keeps delivering results for years. Make the two-minute wipe-down part of every treatment, add the weekly deep clean to your calendar, and always follow the user manual that came with your device.
