General introduction:
Ultrasonic cleaning is used in industry for cleaning t e most precise and delicate parts suc as bearings for
t e aerospace industry or gold and silver jewellery. Ultrasonic ig frequency waves ( 40 kHz ) are
transmitted t roug water creating a process called cavitation. T is creates microscopically small bubbles
between t e surface of t e submerged parts and any small particles on surfaces, suc as dirt. T ese bubbles
burst and pus t e dirt away from surfaces. W en cleaning metal or plastic t e process must be optimised to
avoid damage to surfaces. To do t is it is necessary to control power, temperature and t e time of t e
cleaning process.
T is is ow all dirt in t e grooves of records, even in new pressings is removed. Sonic results are beyond
expectations!
To bring t e ultrasonic cleaning process to every record collector we decided to make t e RD kit's
( rotating and drying kit) purc ase price as low as possible, t us enabling t e customer to purc ase t e
ultrasonic cleaner bat locally (using our guidlines).
The Rotating and Drying record rack kit ( RD kit) will allow you to submerge records in t e ultrasonic
cleaning bat and position t em in a suitable drying position. For 45 EP look Notes on page 15.
It will allow you to clean 10 LPs in one our by t e ultrasonic process, giving you t e cleanest records
ever, free of static c arge.
Brief description of the ultrasonic cleaning process:
Records are positioned on t e spindle wit spacers on t e stand and t en submerged into t e ultrasonic
cleaner warm bat for a limited time. T e liquid is distilled water wit a few drops of isoproply alco ol
and wetting agent added. T e spindle rotates wit t e records, powered by a small motor w ile dipped into
t e liquid just below t e record labels. T e records rotate wit 0.4-0.6 rpm ( less t en one revolution per
minute).
If by any c ance t e record label gets wet no arm is done.
After ultrasonic cleaning t e spindle wit records is lifted out and positioned on t e stand to air dry. W en
dry, any particles on t e record surface are brus ed wit a carbon fibre brus ( records ave no static
electrical c arge ) and t e records are inserted if you wis into new sleeves.
Description of RD kit: (kit does not include ultrasonic cleaner bat )
T e RD kit compromises frame wit motor , supporting legs, spindle for olding records, record spacers, a
clamp for fixing records on t e spindle and a stand for drying records. In t e kit small starter bottles of
isoproply alco ol and wetting agent are also included as well as a carbon fibre cleaning brus and DC
power supply for motor. Kit assembly requires only 10-15 minutes and a meduim size P ilips screwdriver.

RD kit ( rotating and drying) 8 pcs extension legs included
RD kit:
1x main frame wit motor ( DC 9V wit provided mains adaptor)
1x spindle ( record older)
1x drying stand
1x clamp ( grip lock)
8x extension legs( 40 mm- for ig er size cleaners)
10x PVC spacers
1x record carbon brus
1x PVC bottle wetting liquid- as for p otograp y ( for 5 bat fillings)
1x PVC bottle isopropyl alco ol ( for 2 bat fillings)
1x instruction manual
2x Allen keys for leg and rods fixing ( 3mm, 2,5 mm )
2x Allen keys for spindle positioners adjustment ( 2 mm, 1,5 mm)
For 45 EP look Notes on page 15.
To start cleaning your records you need to purchase :
1x ultrasonic cleaner bat
10 liters distilled water( for one filling: 300-400 LPs)

T e main frame is positioned around t e ultrasonic cleaner bat . Records are placed wit spacers on t e
spindle fitted on t e stand. T e spindle olding t e records is t en positioned on top of t e frame w ere t e
motor slowly rotates t em in t e bat .
Frame is positioned over ultrasonic (US) cleaner bat
US cleaner must ave time, temperature and ultrasonic power control. After aprox 10-15 minutes t e
spindle wit t e records is lifted from t e bat and positioned back onto t e stand to air dry records. Once
records are dry , t e top surface of t e record is swept wit t e carbon brus to get rid of any possible dust
particles and t e records put in new record sleeves. As t e records are free of static c arge, t is process is
very easy.

Ultrasonic Bath:
Purc ase an ultrasonic cleaner bat (to our tec nical requirements) following our instructions and
familiarise yourself wit t e instruction manual. Find adequate space and a surface, w ic is not sensitive to
moisture, wit good lig t and a mains outlet. Purc ase at least 10 liters of distilled water.
Position t e ultrasonic cleaning bat on a solid flat surface. Level orizontally if necessary.
For more information ow to prepare t e liquid go to page 12. Once you get familiar wit cleaning process
everyt ing will be really simple. For 45 EP look Notes on page 15.
RD kit assembling and preparation:
Locate t e various RD kit parts. See Fig.1.0. T e only tool w ic is not provided in kit t e for assembling is
medium size P ilips screw driver. You need to assemble t e frame and stand.
