Introduction to the JCR Cleaning System

The Ion-Stream Commercial (150R) is a smart and versatile product designed for routine cleaning of jewellery for display and specifically to clean jewellery set with delicate or chemically reactive stones. It is made to be versatile and simple in use. Its principle use is the quick and safe removal of tarnish from the surface of gold and silver. It can also be used to clean stainless steel and other metals. The 150R can be used with great advantage in conjunction with an ultrasonic cleaner provided the item is not set with delicate stones. To remove tarnish, oxidisation and oil or grease residues from any conductive surface using the electrochemical process of electrolysis.


In use the item is placed in a non-hazardous electrolyte which has a pH of approx 9.1. This means that it is slightly alkaline and can’t damage chemically active gems like opal, ironstone, lapis lazuli, turquoise, coral, pearls etc.


A carefully measured and regulated current is applied to the surface of the item being cleaned irrespective, of the distance between the electrodes. In practice millions of tiny hydrogen bubbles are formed on the conductive surface of the jewellery connected to the cleaning electrode. These bubbles dislodge and then mix oily molecules with the electrolyte, which contains an effective degreaser. Weak molecular bonds which hold the dirt in place are released by the action of the current. The removal of tarnish from silver is almost immediate taking approximately 2 – 5 seconds. Tarnish from gold takes slightly longer at around 5 seconds. This form of cleaning also removes oily and greasy deposits off the surface of gems and diamonds, leaving them sparkling.

The 150R contains an internal timer. This timer automatically starts when the electrodes are placed in the electrolyte. At the end of the cycle the 150R returns to standby mode. The clean cycle can be interrupted at any time by removing one or more electrodes. The timer immediately resets placing the unit in standby mode, ready for the next cleaning cycle.

Charging the internal battery

The 150R contains an internal high quality Ni-MH rechargeable battery pack and battery management circuit. It has been designed to charge the battery at the optimum rate in order to maximise serviceable battery life.

To charge the battery pack plug the charger into the Power socket at the rear of the unit. Only use the supplied charger, and never exceed a continual charge time in excess of 14 hours.

In practice, regardless of the state of charge of the battery, it is quite acceptable to perform an overnight charge before each day of service.

The blue charge light on the front panel will glow to indicate that charging is in progress.

To protect the operator from potential electrical hazards the functionality of the unit is disabled during charging – the charge plug must be unplugged from the back of the 150R before it will operate. Charging may be interrupted and resumed at any time by simply removing the charge jack from the rear of the unit. This ensures the user is isolated from line voltages at all times.

For safety reasons the internal battery is distributed in a discharged state. We recommend that it is given an overnight charge before it is put into service (an overnight charge is defined as a 10 - 14 hours). From this point forward it is quite acceptable to “top-up” the battery pack as required.

After a full overnight charge the battery will typically run for about 150 minutes of continuous cleaning. When used to clean retail stock, a typical clean will take under 8 seconds. A full charge can clean well over 500 items.

When the battery is too discharged to clean, the blue Check indicator will consistently glow. At this point it is advisable to give the battery a complete overnight charge.


The Electrodes and Leads

Probable Causes

Recommended Solution





Check indicator glows continually, or frequently flickers when the electrodes are in the solution.

1) Battery exhausted

2) Cleaning bath too large – too much distance separating electrodes.

3) Contacts on electrode plugs are dirty, or damaged.

1) Charge battery overnight.

2) 300mL – 1L is the ideal capacity for the bath. Depending on the surface area of the item being cleaned, the electrodes should typically be separated by no more than 100mm – reduce distance if required.

3) Inspect, grease and clean plug contacts. Replace if damaged.


Check  and OK indicators on together


Indicates a caution


Refer to solutions above (most probable cause is that the battery needs recharging)


The timer stops the cycle prematurely


This normally occurs when there is a poor electrical connection on either the electrodes or the lead. When this occurs the Check light will frequently flicker during the cycle.


Make sure all electrode contacts, plugs and sockets are clean. Pay particular attention to the connection between the item being cleaned and the hook electrode. The source of the poor connection can be traced quickly by moving each connection point during a cycle whilst observing the state of the Check light.


When the charger is plugged in, the unit will not operate.


No mains power, or incorrect plug pack.


1) Ensure you are using the correct plug pack!


2) Check that the mains power is on, and that the plug pack is fully pushed into the wall socket.


The battery does not hold it’s charge


The battery may need replacing.


In practice the battery normally needs replacing after 2-3 years of commercial use.




1) If the battery has not been used for many months or years It may be possible to rejuvenate the battery by multiple consecutive charge/discharge cycles.


2) Contact distributor for a battery replacement kit or send the unit back to JCR Solutions for service.
