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.

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.

US cleaner bath filling: Fig.8.0.
For t e first time read bat preparation on page 5 again. Plug in mains connector to US bat after you fill in
liquid. As you know you should NOT switch on ultrasonics without water in the bath!
Preparation of liquid:
Pour distilled water into bat to about 50 mm below t e top edge. It will be topped up later. Add 100 ml
isopropy alco ol and 10-15 drops of wetting liquid ( agent). Precise quantities are not important.
Switc on ultrasonic cleaning for 15 minutes and set temperature at 30 deg Celsious ( C). T is will prepare
and mix liquid and more important minimise air bubbles in t e liquid itself for maximum cleaning effect.
Add or remove some liquid to get desired level of liquid. Fig. 8.0.
Fig. 8.0. US cleaner bat wit water Fig. 8.1. Drain tap in closed position
Power adjustment:
Full power will create big ripples on t e surface- t is will mix water and minimise air bubbles.
At some point reduce power for a s ort time so t at only small ripples are visible. Mark t at position! T is
is t e working US cleaning power for record cleaning. Wit more records in t e bat you mig t increase t e
power a little . It is important t at you keep t e power level in t is range but a bit more will be just fine.
Working conditions:
Temperature: 30-33 deg C ( you can experiment up to 40 deg C)
Time: 15 minutes ( but it is not critical if less)
Power: adjust it till ripples are very small on top surface ( about 50-70 % of full power)
Spindle positioning on frame over bath: Fig. 9.0.
We suggest t at for first time you use only few old unimportant records to familiarise yourself wit t e
cleaning process.
Carefully lower t e spindle wit records onto t e frame. Observe t e records eig t and water level ( around
25 mm t e top edge of t e bat ). Observe t e edges of bat to fit records in it. Position spindle wit toot
w eel on top of motor toot w eel. Spindle s ould neatly sit in t e two bearing support. Fig. 9.2. Wit some
cleaners you mig t need to reposition spindle positioners by using allen keys- see Fig. 1.1 &9.5.
Water level s ould be below record labels. But w en more records are submerged t e water level will rise a
little. Adjust water level accordingly by adding more water or removing it . Also try readjusting t e frame
eig t. Adjust liquid to raise 5-10 mm below record label. Wit use c eck liquid level and add some water
if need it.

W en you are satisfied switc on rotation and ensure records rotate. T e water level s ould be below t e
black spacers or labels. If necessary retig ten records by pus ing t e clamp towards t e records.
W en you switc on t e ultrasonic power and you may notice bubbles forming inside t e bat or on t e
record surfaces. T e cleaner t e record, t e less bubbles will be seen. Do not forget t at t e main aim is
cleaning inside t e record grooves and t ese bubbles are NOT visible. You will see your records s inier
t en ever after t e cleaning process.
If t e water wets t e labels- do not worry as it will dry up wit out any damage.

Spindle lifting and positioning in drying position: Fig.10.0.
W en t e time is nearly fins ed very slowly lift up t e spindle wit records and gently s ake it. Position
spindle wit records in tilted ole- keeping t e wetter part of t e records in t e lower position.
Less water is stuck on record surfaces if t e ultrasonic is still working w ile lifting records out of t e bat .*
Of course you can also lift records out of t e bat after ultrasonic is turned off. Drying takes about 30-40
minutes. You can s ake t e spindle.

Record wiping and storing: Fig. 11.0.
W en records are dry (c eck after 40-60 min.), position spindle back in t e vertical position on t e stand
and you are now ready to put your clean records back in t e sleeves.

During t e cleaning process small particles of dust collect in t e bat or may ave fallen from your clot es
so w en t e records are dry you mig t see some of t ese particles on top of t e record surface.
Removing particles from t e record surface wit a carbon fibre brus is very easy due to t e lack of static
electricity.
Some ot er US cleaners dry records quicker but t is makes records statically c arged again.
Remove t e clamp by pressing t e button and wit fingers of one and old outer record edge, pus down
label and rotate record. Wit second and old brus and remove particles. Use good lig t. Fig. 11.1.
Lift up record, flip it over and repeat cleaning of t e second side. T en insert clean record into clean sleeves.
Remove all remaining records one at a time in t e same way.
Finishing cleaning:
W en not in use cover bat wit a lid. If you are not planning to use it for more t en 8 ours we suggest you
switc off t e bat .
Increasing production:
If you would like to clean more records in one session you s ould purc ase a spare spindle wit spacers and
stand. Two extra sets will allow you to clean 30 records in 60-70 minutes. You need to purc ase spare
stand wit spindle: Fig. 1.1& 1.2. To speed up drying process use slow blowing fan.
Notes:
-After you clean a few records you will get used to t e process and you will find it very easy to use.
-You may notice a fine black powder in t e water. Due to t e nature of t e cleaning process t is will not get
in t e grooves. We suggest you clean 300-400 records before replacing liquid.
- If your records are very dirty t en t e liquid will collect dirt . We suggest you clean very dirty records first
wit vacuum cleaning or clean very dirty records just before you are planning to replace water wit new.
-You mig t observe t at records will bend w en submerged in warm liquid ( over 35 deg C) but t ey will
flatten after a few revolution in bat .
-* If you ave time leave records rotating in bat after t e ultrasonic was for additional 15 minutes. In t is
way t e least particles will stay on top surface of t e record.
For 45 EP( singles) cleaning: ask for 45 adaptors to center records and fit t em as on p oto- but you mig t
need to erase liquid level in bat .
