General introduction:
Ultrasonic cleaning is used in industry for cleaning the most precise and delicate parts such as bearings for
the aerospace industry or gold and silver jewellery. Ultrasonic high frequency waves ( 40 kHz ) are
transmitted through water creating a process called cavitation. This creates microscopically small bubbles
between the surface of the submerged parts and any small particles on surfaces, such as dirt. These bubbles
burst and push the dirt away from surfaces. When cleaning metal or plastic the process must be optimised to
avoid damage to surfaces. To do this it is necessary to control power, temperature and the time of the
cleaning process.
This is how all dirt in the grooves of records, even in new pressings is removed. Sonic results are beyond
expectations!
To bring the ultrasonic cleaning process to every record collector we decided to make the RD kit's
( rotating and drying kit) purchase price as low as possible, thus enabling the customer to purchase the
ultrasonic cleaner bath locally (using our guidlines).
The Rotating and Drying record rack kit ( RD kit) will allow you to submerge records in the ultrasonic
cleaning bath and position them in a suitable drying position.
It will allow you to clean 10 LPs in one hour by the ultrasonic process, giving you the cleanest records
ever, free of static charge.
Brief description of the ultrasonic cleaning process:
Records are positioned on the spindle with spacers on the stand and then submerged into the ultrasonic
cleaner warm bath for a limited time. The liquid is distilled water with a few drops of isoproply alcohol
and wetting agent added. The spindle rotates with the records, powered by a small motor while dipped into
the liquid just below the record labels. The records rotate with 0.4-0.6 rpm ( less then one revolution per
minute).
If by any chance the record label gets wet no harm is done.
After ultrasonic cleaning the spindle with records is lifted out and positioned on the stand to air dry. When
dry, any particles on the record surface are brushed with a carbon fibre brush ( records have no static
electrical charge ) and the records are inserted if you wish into new sleeves.
Description of RD kit: (kit does not include ultrasonic cleaner bath)
The RD kit compromises frame with motor , supporting legs, spindle for holding records, record spacers, a
clamp for fixing records on the spindle and a stand for drying records. In the kit small starter bottles of
isoproply alcohol and wetting agent are also included as well as a carbon fibre cleaning brush and DC
power supply for motor. Kit assembly requires only 10-15 minutes and a meduim size Philips screwdriver.

The main frame is positioned around the ultrasonic cleaner bath. Records are placed with spacers on the
spindle fitted on the stand. The spindle holding the records is then positioned on top of the frame where the
motor slowly rotates them in the bath.
Frame is positioned over ultrasonic (US) cleaner bath
US cleaner must have time, temperature and ultrasonic power control. After aprox 10-15 minutes the
spindle with the records is lifted from the bath and positioned back onto the stand to air dry records. Once
records are dry , the top surface of the record is swept with the carbon brush to get rid of any possible dust
particles and the records put in new record sleeves. As the records are free of static charge, this process is
very easy.

Technical requirements for ultrasonic cleaner bath:
There are various ultrasonic cleners on the market. Simply look into the technical data and if they meet the
following criteria it will clean safely.
Bath inner size: min 297 x 220 x 135 (mm: Lenght x Width x Depth )
max 305 x 240 x 150 (mm: L x W x D)
Cleaner outer size: min 325 x 265 x 270 (mm: Lenght x Width x Height )
Max 365 x 278 x 395 (mm: L x W x H )
(special size frame can be made on request)
Volume: min 8-10 lit ( depends on the bath size)
Ultrasonic frequency: 35-40 kHz
Temperature control: min 20-50 Celsius range ( suggested temperature is 30-33 C degrees)
Timer: min 5-20 minutes range (suggested cleaning time is 10-15 minutes)
Power control: 0-100% ( suggested cleaning power is 50-60 % of full power)
In case of doubt ask your dealer or us directly, sending us technical details about cleaner.

Ultrasonic record cleaning process with RD kit
Ultrasonic Bath:
Purchase an ultrasonic cleaner bath (to our technical requirements) following our instructions and
familiarise yourself with the instruction manual. Find adequate space and a surface, which is not sensitive to
moisture, with good light and a mains outlet. Purchase at least 10 liters of distilled water.
Position the ultrasonic cleaning bath on a solid flat surface. Level horizontally if necessary.
For more information how to prepare the liquid go to page 12. Once you get familiar with cleaning process
everything will be really simple.
RD kit assembling and preparation:
Locate the various RD kit parts. See Fig.1.0. The only tool which is not provided in kit the for assembling is
medium size Philips screw driver. You need to assemble the frame and stand.
