A podiatry ultrasonic cleaner uses high-frequency
sound in a liquid bath to help remove contamination from compatible
reusable instruments. It can reduce manual handling and reach parts that
are difficult to brush, but it does not automatically disinfect or
sterilise an instrument.
The cleaner is one stage in a documented decontamination process. The
correct process depends on the exact instrument, its intended use, the
instrument manufacturer’s instructions, the cleaner instructions and the
clinic’s risk assessment and procedures.
This guide covers equipment selection and operation. It does not
replace manufacturer instructions, professional training or a
clinic-specific decontamination protocol.
Short answer
An ultrasonic cleaner can be useful when the bath, detergent, cycle
and load have been selected for the instruments being processed. Results
depend on correct loading, solution condition, temperature, cycle time,
maintenance and performance checks.
Do not use a universal instruction copied from another cleaner. Fill
level, solution concentration, temperature, cycle time, degassing, test
method and maintenance frequency vary between models and processes.
Ultrasonic cleaning does not replace any later disinfection or
sterilisation step required for the instrument and its intended use.
What ultrasonic cleaning
does
An ultrasonic bath creates cavitation in the cleaning liquid. The
action helps loosen material from instrument surfaces, joints and other
accessible areas. Cleaning effectiveness still depends on the complete
process, including pre-treatment, detergent, load arrangement, cycle
settings, rinsing, inspection and drying.
Cleaning removes contamination. Sterilisation uses a validated
process to render viable microorganisms inactive to the required level.
A visibly clean instrument is not proof of sterility, and a completed
cleaning cycle is not proof that an instrument is suitable for patient
use.
The MHRA advises healthcare organisations to consider decontamination
requirements before buying reusable medical devices and to follow the
manufacturer’s cleaning and decontamination instructions. The Health and
Social Care Act infection-control code also states that reusable medical
devices should be decontaminated in line with manufacturer instructions
and current national or local good practice.
22 checks for a
podiatry ultrasonic cleaner
Before buying
-
Define the instruments and process. List the
reusable instruments, materials, joints, lumens and burs that may enter
the bath. Confirm the required downstream process for each
instrument. -
Check instrument compatibility. Obtain the
current instructions for each instrument. Do not place an item in an
ultrasonic bath unless its manufacturer permits the method. -
Exclude single-use items. Do not reprocess a
device labelled single use. The MHRA advises against reprocessing
single-use medical devices outside the applicable regulated
arrangements. -
Choose a usable tank size. Compare the working
dimensions of the tank and basket with the clinic’s normal load. A large
quoted litre capacity does not prove that long or hinged instruments fit
correctly. -
Check the basket and accessories. Confirm that
the supplied basket, cassette, beaker or bur holder suits the load and
keeps instruments away from the tank base where required by the cleaner
instructions. -
Plan the location. Check the electrical supply,
worktop, ventilation, drainage, safe filling and emptying, and the route
from contaminated to clean instruments. Include the space needed to open
the lid and remove the basket without crossing clean work. -
Check records, testing and servicing. Ask what
cycle records the machine provides, which routine checks the
manufacturer specifies, who can service it and what evidence is supplied
after maintenance or repair. -
Price the complete process. Include the cleaner,
baskets, lids, drain fittings, approved detergent, dosing equipment,
test materials, servicing, repairs and staff time. Compare several years
of likely cost rather than the machine price alone.
Before and during each cycle
-
Use a written procedure. Staff should have
instructions for load preparation, detergent, settings, PPE, cycle
release, inspection, faults and record keeping. -
Inspect the cleaner. Check the tank, basket,
lid, drain, cable and controls before use. Remove the cleaner from
service if damage, leakage or a fault could affect safety or
performance. -
Use the specified cleaning agent. Follow the
cleaner and instrument instructions for the detergent or cleaning
solution. Water alone, a household product or a solution recommended for
another model may give poor results or damage equipment. -
Measure the correct concentration. Use the
stated dosing method. A stronger solution is not automatically more
effective and may create residue, damage or staff exposure. -
Use the model’s fill level and temperature. Do
not apply the old rule that every tank should be filled to about 25 mm
from the top. Use the marked level and temperature range in the current
instructions. -
Degas when instructed. Fresh solution can
contain dissolved air that affects ultrasonic activity. Use the
machine’s degas setting or the stated procedure when its instructions
require it. -
Prepare instruments correctly. Open hinges and
dismantle instruments only where the instrument instructions require and
permit it. Do not force apart components that are not designed for
separation. -
Load the basket without overcrowding. Keep
instruments positioned so the solution can reach relevant surfaces. Do
not place items directly on the tank base unless the manufacturer
expressly permits it. -
Control chemical and sharps risks. Use the
clinic’s COSHH assessment and sharps procedure. Select gloves, eye
protection, apron and other controls from the assessed task and the
product safety information. -
Close the lid and use the stated cycle. The lid
can help control splashes, aerosols and noise. Use the cycle time,
temperature and settings specified for the machine, solution and
load.
After each cycle
-
Remove the basket safely. Avoid placing hands
into the bath. Use the basket, handles or tools described in the
operating procedure and allow for hot liquid or surfaces. -
Rinse, inspect and dry as required. Follow the
instrument and cleaner instructions. Check instruments under suitable
lighting. An instrument with visible contamination should not pass to
the next stage. -
Move instruments to the next documented stage.
Protect cleaned instruments from recontamination. Ultrasonic cleaning
does not replace any required disinfection, packaging or sterilisation
process. -
Manage the bath and records. Change solution,
drain, clean and dry the tank at the frequency stated in the written
procedure and manufacturer instructions. Record cycles, routine checks,
faults, maintenance and corrective action at the level required by the
clinic’s system.
Testing and performance
checks
There is no single test schedule that can be applied to every
podiatry ultrasonic cleaner. Follow the cleaner manufacturer’s current
instructions, the clinic’s chosen good-practice framework and any
applicable commissioning or validation requirements.
Possible checks include cycle-control checks, ultrasonic-activity
checks and cleaning-efficacy tests. The accepted method, frequency, pass
criteria and response to a failure must come from the relevant
instructions or adopted standard. Do not copy a foil, energy-meter or
soil-test method from a different machine without confirming that it is
suitable.
Health Technical Memorandum 01-05 contains detailed
ultrasonic-cleaner guidance for primary-care dental practices. It can
provide useful technical context, but its stated scope is dentistry. Do
not present every dental requirement as a blanket rule for independent
podiatry or Foot Health Professional practice.
Cleaning solution and COSHH
Cleaning products can create skin, eye, inhalation or environmental
risks. Keep the current safety data sheet available and complete a COSHH
assessment for the way the product is stored, diluted, used and disposed
of.
Check:
- approved concentration and dosing method;
- permitted water quality and temperature;
- contact time and cycle settings;
- material compatibility;
- shelf life and solution-change rules;
- required PPE and spill response;
- drainage and disposal instructions;
- storage and labelling after opening or dilution.
Do not combine products unless the manufacturer expressly instructs
it. Never assume that bleach, acid, alcohol, a household detergent or a
generic disinfectant is suitable for the tank or instruments.
How to compare
podiatry ultrasonic cleaners
Request written information for the exact model and
configuration.
| Buying point | What to compare |
|---|---|
| Intended use | Instrument types, materials and stated medical or professional applications |
| Working capacity | Tank and basket dimensions, usable load and instrument layout |
| Controls | Time, temperature, degas function, presets and user access |
| Records | Displayed results, printer or electronic logging, data export and clock control |
| Routine checks | Manufacturer test method, test materials, frequency and pass criteria |
| Workflow | Lid, basket handling, drain, filling, emptying, rinsing and drying |
| Consumables | Approved detergent, test products, baskets, cassettes and replacement parts |
| Support | Installation, training, warranty, servicing, repair turnaround and loan equipment |
| Installed cost | VAT, delivery, plumbing or drainage, accessories, consumables and service cover |
Current UK suppliers list small benchtop cleaners and larger machines
with more process control and record functions. These product groups are
not interchangeable. A compact general bath may suit a limited validated
load, while a higher-specification unit may offer drainage, locking,
data logging or testing features that support a busier clinic’s
procedure.
Use the UK
podiatry supplier directory to request comparable quotations.
Confirm current availability, intended use and support in writing.
Buying a second-hand
ultrasonic cleaner
For a used cleaner, ask for:
- manufacturer, model, serial number and age;
- intended-use information and current instructions;
- tank, basket, lid, drain, cable and control condition;
- service, repair, commissioning and test records;
- known faults and the reason for sale;
- availability of approved detergent, test products and spare
parts; - current manufacturer or authorised service support;
- a demonstration using the normal controls without processing patient
instruments.
A machine that powers on and produces noise has not proved cleaning
performance. Arrange an appropriate inspection, service or performance
check before clinical use.

Common questions
Does an
ultrasonic cleaner sterilise instruments?
No. Ultrasonic cleaning is a cleaning process. It does not replace a
validated sterilisation process where sterilisation is required for the
instrument and its intended use.
For equipment-selection context, read the podiatry
autoclave buying guide.
Should
every cleaner use distilled water and detergent?
There is no universal instruction. Use the water quality, cleaning
agent, concentration and temperature stated for the exact cleaner,
instruments and adopted process.
Do operators need to
stand one metre away?
The old article gave this as a universal rule without adequate
support. Follow the machine’s noise information, operating instructions
and the clinic’s risk assessment. Keep the lid closed during the cycle
where the instructions require it.
Can a
domestic ultrasonic cleaner be used in a clinic?
Do not choose a cleaner from price or tank size alone. Obtain written
evidence of intended use, instrument compatibility, operating
instructions, performance checks, service support and the records needed
for the clinic’s process.
Summary
Choose a podiatry ultrasonic cleaner around the instruments, workflow
and documented decontamination process. Compare the usable basket,
controls, detergent, records, routine checks, service support and
whole-life cost.
During use, follow the exact machine and instrument instructions.
Correct loading, solution control, inspection, testing and records
matter as much as the ultrasonic bath itself. Treat cleaning,
disinfection and sterilisation as separate terms and do not claim that a
cleaning cycle completes every decontamination requirement.
Comment update — September 2026: The comments below were published in 2015. Ultrasonic cleaning is a cleaning stage, not sterilisation and not proof that an instrument is ready for reuse. The required process depends on the exact instrument, intended use, manufacturer instructions, risk assessment and current professional or local guidance.
Is it necessary to purchase an autoclave for a podiatry practice. Would using ultrasonic technology be adequate for clean instruments. It seems that a large majority of treatments do not require sterile instruments. I feel that the use of an autoclave is overkill. I would appreciate your insight. Thank you
Thank you for your comment Dr Vona. As the saying goes “clean is not sterile and sterile is not clean” The use of an autoclave is an effective way of sterilizing instruments and an ultrasonic clean used prior to sterilization, ensures the instruments are thoroughly clean. Any instrument that comes into contact with a patient should be decontaminated to the necessary level. An effective risk assessment should form the basis of a good decontamination procedure. I do appreciate that weighing up the implications of cost and time takes careful consideration. A well documented procedure along with effective training can reduce time and costs significantly.
