Ultrasonic Auto Parts Cleaners for Time Saving Superior Results

tova-carb-large.jpg

An ultrasonic auto parts cleaner is a mechanics best friend.  No other method beats the speed and thoroughness of an ultrasonic auto parts cleaner when it comes to cleaning, restoring and maintaining all components of internal combustion engine and drive train assemblies.

Whether you are a shade tree mechanic or are in charge of the service department of major auto, truck or other dealerships, you can rely on Tovatech's family of ultrasonic carburetor, engine and drive train parts cleaners deliver high performance, industrial strength, cleansing action.

Where You'll Find Ultrasonic Auto Parts Cleaners:

  • small engine repair shops
  • automotive and small engine training schools
  • on- and off-road vehicle maintenance bays
  • DIY mechanics' sheds and garages
  • lawn & garden power equipment sales and service establishments
  • marine and other recreation engine maintenance service specialists
  • transmission and power train component maintenance services
  • classic car restoration specialists

7 Good Reasons why Mechanics Depend on Ultrasonic Auto Parts Cleaners:

  1. To clean carbon deposits from carburetors and all manner of engine parts
  2. To remove stubborn oil, grease, lubricants, paint, rust, and dirt (with pre-cleaning in some cases)
  3. Because the process is safe for aluminum parts
  4. Best way to penetrate deep into parts and clean holes, small apertures and crevices
  5. A safe way to clean sensitive parts like wiring and plastic without damage
  6. Process does not require ‘line-of-sight’ for effective cleaning
  7. Helps ensure part longevity due to a high degree of cleanliness

How Ultrasonic Auto Parts Cleaners Work

Ultrasonic cavitation or the implosion of millions of minute bubbles against surfaces immersed in an ultrasonic cleaner tank filled with a cleaning solution formulated for the job (see below).    

The bubbles are created by ultrasonic transducers bonded to the cleaner’s tank.   A widely used ultrasonic frequency is 37,000 cycles per second (37 kHz) delivered by the Elmasonic E Plus series of cleaners available from Tovatech.  

The E Plus series come in 9 sizes from 0.25 to 7.5 gallons.  All are equipped with a heater and timer along with an automatic sweep mode that evenly distributes ultrasonic energy through the bath for more uniform auto parts cleaning action.

Larger auto parts and drive train components can be quickly and thoroughly cleaned using an industrial auto parts cleaner such as the Elma xtra ST units available with capacities to 67 gallons or the Shiraclean units with capacities to 110 gallons.

A Short Course on Ultrasonic Auto Parts Cleaning  

Vo-Tech and apprenticeship programs offering engine repair courses will include sessions on ultrasonic cleaning procedures to help students increase the efficiency of their future careers.  They learn that the ultrasonic process is much more effective than manual scrubbing with solvents in wash tanks and is also faster and safer. 

That’s why it is preferred when removing dirt, grease, crud, carbon and varnish deposits, and other contaminants from engine parts such as carburetors, gears, crankshafts, transmissions, oil pans and bearings. 

Ultrasonic cleaning completes the task in minutes and more thoroughly than manual cleaning can ever achieve.  It’s also safe for rubber or other non-metallic components that can be safely wetted in the ultrasonic cleaning solution.

How to Clean Engine Parts

Elma tec A4 Concentrated Carb CleanerA recommended ultrasonic cleaning solution is elma tec clean A4 concentrate, an alkaline formulation for metal, glass, ceramics, plastic and rubber.  It removes oil, grease, combustion residues, soot and other organic contaminants when diluted to 2 to 5% with water. 

Here is an example of a cleaning cycle using the Elmasonic E Plus ultrasonic cleaner:

  1. Add water to the tank fill line and the required amount of elma tec clean A4 to make a 5% concentration.  (A 2.5 liter container of concentrate dilutes to approximately 9 gallons of solution.)
  2. Turn on the cleaner and allow it to operate for approximately 15 minutes.  This degassing step drives off entrapped air and must be taken each time fresh cleaning solution is prepared.
  3. Prior to cleaning set the thermostat to 70˚C and turn the unit on.  While the solution warms place parts in the mesh cleaning basket in such a way that they do not come in contact with each other.
  4. Lower the basket into the cleaning solution, place the lid on the tank to conserve heat, reduce noise and evaporation.  Set the timer for 20 minutes. Cleaning time depends on the condition of the parts and can be adjusted either way.  While cleaning takes place mechanics can attend to other tasks.
  5. At the end of the cycle remove the component(s) from the bath.  If they need further cleaning run them through another cycle.  Do not reach into the hot cleaning solution.  Instead remove the basket if you want to inspect or rearrange the parts.
  6. Allow the parts to flash dry before reassembly.  

If rust is a concern add 0.05 to 0.5% elma-KS to the cleaning solution. This provides a protective coating on a molecular level for temporary corrosion protection.

Hot to Maintain Ultrasonic Auto Parts Cleaning Solutions

As suggested above, the duration of the ultrasonic cleaning cycle is governed by the condition of parts being cleaned. A good practice is removing loose gross contaminants before placing parts in the bath. 

During the operation contaminants that float to the surface should be skimmed off and set aside for proper disposal. 

When the cleaning solution loses effectiveness, it is time to drain and clean the tank with a water spray.   This removes particles that have settled to the bottom and cause tank damage if allowed to remain over time. While elma tec clean A4 is biodegradable spent solution will contain contaminants and must be disposed of according to local regulations. 

More Examples of Ultrasonic Auto Parts Cleaning

Owners of small engine repair shops more easily accommodate seasonal peaks in demand when they use an ultrasonic cleaner instead of manually scrubbing carburetors, engine blocks and other engine components in harmful solvents that can also present a disposal problem.

Automobile transmission service companies, rebuilders and backyard mechanics can save a tremendous amount of time by using ultrasonic cleaning to remove dirt, grease, metal shavings and other deposits.

Savvy anglers take care of their motorboat engines, and one way to help ensure a fine day afloat is periodically cleaning engine parts in an ultrasonic engine cleaner.

Disassembled drive train parts with deposits of carbon, varnish, sludge, road dirt and similar contaminants familiar to the auto mechanic are quickly and safely cleaned in benchtop or floor mounted ultrasonic cleaners.

Cleaning carburetors can be time-consuming using solvent wash tanks, brushes and aerosol sprays.  Professional results are obtained when an ultrasonic cleaner is used to restore carburetors to a like-new condition.  Other benefits: reduced labor costs and cleaning in as few as 20 minutes. 

For effective cleaning the ultrasonic cleaner must use the right cleaning chemistry, operate at the right temperature, and use the correct frequency.  The part to be cleaned, the contaminant to be removed, and the degree of soil, determine this.  Our years of experience advising manufacturing and maintenance clients on the right process for their cleaning needs help us identify the exact product combo that you need.  Just call us and we’ll guide you to the right solution quickly.
