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.
