Vinyl Record Cleaning

 If you have collected the old or new vinyl records, you will know the importance to keep them clean and dustless. The playback quality of economic records equipped with middle-end stylus can also be improved significantly by cleaning their vinyls. No matter how cautiously you put one record aside, the dust will enter the internal sleeve gradually after a long time. When cleaning the records, if the dust can not be eliminated, then the audio track will be damaged. The problem is how to clean the vinyl records safely without damaging the record surface? The answer is ultrasonic vinyl record cleaners.  

   The new type record bracket and rotary electric machine have been created by Granbo, integrating with the 6.5 L and 180 W cleaning trough of Granbo desktop ultrasonic cleaners. The new type record bracket can usually accommodate 6 to 8 records at a time, each record bracket can be isolated by circular plastic waterproof pad and rubber ring, preventing the record label from moistening. 

The Features of Granbo Vinyl Record Cleaners：
1.Being able to clean 8 vinyl records simultaneously.
2. Adjusting the lifter to optimal cleaning position conveniently. 
3. One-click control for the rotary cleaning of vinyl records. 
4. Removing the dirt/eliminating the crackle quickly.
5. With durable stainless steel structure.
6. The internally equipped transducer can strengthen the ultrasonic power, and producing excellent cleaning effect.
7. The stainless steel cleaning basket can be utilized for cleaning small objects with less friction, reducing the frictions between small objects and tanks.
8. The drain-pipe with traffic control valve, convenient for cleaning and washing.
9. Non-slip rubber feet.
10. Conducting general cleaning with tap water/pure water, you can add the professional cleaning fluid for improving the efficiency. 

• First of all, installing the records on main axis.
• Filling in pure water in water slot, tap water can not be used, and adding 10 to 15ml drops of domestic liquid detergent. 
• Adding the pure water to the position with 1cm distance from the edge.
• Then descending the records to water slot, the water separation panel design can prevent the labels from getting wet.
•  If the water temperature is lower than 10 centigrade, launching the heating function, setting the cleaning time as 5 to 15 minutes, setting according to the record condition. 
•  Lifting the records, air-drying vertically. 

• If the LP is very dirty, pure water + absolute ethyl alcohol (purchasing 95 percent alcohol in drugstores) + 0.25 percent isopropanol (only for extremely dirty records, which can be purchased in chemical reagent stores) + surface active agent (which can be replaced by neutral detergent). Proportion: 62 percent water, 30 percent ethyl alcohol, 8 percent isopropanol, with 1ml of neutral detergent.
•  If the Lp record is not very dirty, only 500 ml ethyl alcohol needs to be added in tanks, then adding pure water, and at last, adding 1 ml neutral detergent. 

     Ultrasonic method is verified to be safe and efficient, which can remove the dust, dirt, grease dirt and other contaminants on refined objects, it can be applied extensively in industries and scientific environment. 

     For record lovers, only ultrasonic cleaning is available for cleaning the extremely refined record concave troughs, and it is the only method for restoring them to the required original status that simulating high-fidelity audio.      

     Different from manual cleaning, ultrasonic cleaning can remove the particles in the concave trough of vinyl record efficiently.  

     As it has been described above, the cavitation bubbles produced by ultrasonic can enter the audio tracks of records more efficiently than any other tools.

     Gerry is a collector living in the Spring Hill of Florida, and he has at least 4500 records. 

    “For maintaining (or restoring) such sound quality, no other thing is better than the desktop ultrasonic cleaner, it is equipped with a kind of electric machine which can rotate the records pass in and out of the cleaning solvent,” he remarked. “Ultrasonic is safer and quicker, which can remove the dust and other contaminants that can affect the quality in concave trough completely. 

    “In my opinion, ultrasonic cleaning can improve the record cleaning to a new level” he said.

    “The frequency from 37 kHz to 40 kHz is more suitable for eliminating heavier dirt deposit sediment, and the relatively higher frequency and its relatively small cavitation bubbles can assure the cleaning effect to penetrate the refined concave trough in vinyl,” Gerry explained.
