"I have to declare that the KARC-1 is the best record cleaner on the market. Bar none.​"​

A revolutionary Ultrasonic Record Cleaning and Record Groove Restoration System. Using a spray that ionizes the record, it not only SURFACE CLEANS, but removes the release agent where dust at the pressing plant lands on a hot record and is fused into this oil, causing those unwanted pops. result: a 1.3 to 3-4 dB gain over floor. Detail as pressed by the stamper revealed!

(for the 120VAC U.S. model for U.S. Clients, RESTORES 2 X LP, 1 X 10"/78, 1 X 45 RECORDS SIMULTANEOUSLY in 18 to 20/25 minutes. Records come out virtually dry, no need for vacuum or air drying)*

Seeing, Hearing, Is Believing. The Images Validate Our Process. Learn about the science:

  • Our development process started 11 years ago. Supported by consulting engineers and chemists, now selling in our 6th year, the Kirmuss KA-RC-1/2 is recognized globally as a RECORD RESTORATION SYSTEM and not a record surface cleaner or jewelry or dental ultrasonic with DIY skewer assemblies.

    Indeed we use cavitation, but where records and water have the same charge and repel each other, so we need to do more to get into the groove!

    Our unique IP sees one apply a PVC safe and record groove friendly water soluble ionizing surfactant spray applied to the record. Once the record is inserted, it spins, attracting cavitation. Other sonics and vacuum or manual cleaning methods can only clean surfaces as the PVC of the record repels water and soaps as both have the same relative slightly negative electrical charge. Like chares repel, that is why cleaning agents "pool" on the record as they are repelled by the record. That is why one needs to dry a record using a vacuum or forced air dryer (fan). Not with the Kirmuss.

    As to our cycling a record in and out of our machine: As the record spins, the charge wears off. That is why one needs to reapply the spray with the supplied brush.

    Over several cycles, we first remove films left over from prior cleaning processes, (that were air or vacuum dried onto the record), then the release agent (Pressing oil as discovered by the Shure Brothers, circa 1977), where dust and dirt at the pressing plant are fused into this cooling material, cause of those unwanted pops.

    Films and release agent removed, the needle is picking up the detail of the record once hidden.

    The ionizing agent has a colorant added. This allows one between applications to see what the ultrasonic and cavitation softened in the previous cycle. When this rapidly evaporates, that is indication where there is nothing left in the groove to removed.

    New records 16 years or younger undergo a fixed 5, 4, 4, 4, 5 minute cycle.

    RESULT: A 1.3 to 3/4 dB gain over floor.
    Increased imagery, timbre, soundstage.
    ...Like opening a window!

    Is your ultrasonic actually using cavitation?

    If you review our training videos we use a simple aluminum foil record to verify the presence and even distribution of cavitation. One 40 KHz German Made advertised ultrasonic as well as a 40 KHz machine made in Hong Kong ARE NOT ULTRASONICS USING CAVITATION, rather, are ultrasonic bubblers!

    Mr. Michael Fremer (Trackingangle.com) has commented: FINALLY! CAVITATION EXPLAINED CLEARLY AND CONCISELY.

    What exactly is "cavitation" as applied to record cleaning? None of the novelty videos on YouTube explain what it is and most of them make recommendations that clearly indicate the advocates have no idea what they are talking about! In fact, many of the "cavitation" machines do not actually cavitate. After editing this video and watching it a second time, I feel fully confident in claiming that this video is among, if not the most important and useful video you will find on YouTube— if you are serious about vinyl playback and proper record care.

    In our generic training videos and in Mr. Fremer's video, see for yourself how the aluminum foil test also proves that 12 records skewered on DIY rotisserie style attachments see no even ultrasonic cavitation action on the record.

    Due to the law of ultrasonic loading in a 7.5 liter bath: We cannot process more than 4 records simultaneously as the records need to be spaced no less than 1.78 inches apart to see all grooves made contact with the effects of cavitation, cleaned and release agent removed, thus restoring the record. Any closer as with DIY or skewered or copy cat systems with 12 records suspended see standing waves created by the records being in too close a proximity with each other and as such negates the effect of cavitation where only the first inch or so from the outer edge of the records are cleaned at best.

  • Professional and Safe: Our system meets electrical and safety standards. (ETL Certified to meet CSA, UL, PS, FCC and CE). WHAT ABOUT YOURS? A LISTED EXTERNAL LAPTOP STYLE POWER SUPPLY DOES NOT REFER TO PRODUCT SAFETY!
  • Safe for shellacked or lacquered records, restores, not just “surface—cleans”. (2 minute cycle)
  • ALL TOLD: We bring life back to music, it's like playing what the lathe cut into the lacquer!

    CLEANS AND RESTORES 4 RECORDS AT A TIME REMOVING THE RELEASE AGENT IN  18 or 15 TO 25 MINUTES depending on using a 2 minute or 5 minute cycle! (Consult the FAQ section as to when to revert to a 2 minute cycle.)
