Why does the Disco-Antistat Ultrasonic work at 46 kHz – and not at 80 or 120 kHz?

Why does the Disco-Antistat Ultrasonic work at 46 kHz – and not 80 or 120 kHz?

A question we hear again and again.

---

If you've ever looked into ultrasonic record cleaning machines, you might have noticed:

Many manufacturers advertise the highest possible ultrasonic frequencies.

60 kHz.

80 kHz.

120 kHz.

This suggests an assumption: the higher the number, the better the cleaning result.

However, it's not that simple.

---

The most important number is not the frequency.

What's important is the cleaning result.

When developing the Disco-Antistat Ultrasonic, we therefore asked ourselves a different question:

How do we clean records as thoroughly as possible – without unnecessarily stressing the vinyl?

The answer is not "higher frequency", but the perfect interplay of all components.

Why exactly 46 kHz?

46 kHz has proven to be the optimal compromise in our development and long-term tests.

The ultrasonic waves reliably remove dirt from the fine grooves.

At the same time, the system works gently on materials and is safe for vinyl.

But for us, ultrasound is only one part of the whole.

---

Why does the ultrasonic always switch off?

We also get this question frequently.

The answer is simple: ultrasound generates heat.

If it were to run continuously, the cleaning fluid could continue to heat up.

However, vinyl reacts sensitively to temperatures around 35 °C.

That's why the Disco-Antistat Ultrasonic deliberately operates in intermittent mode.

This keeps the temperature in the optimal range – and your records are cleaned particularly gently. This mode of operation is a conscious design decision and serves to protect the vinyl.

---

Why don't we only clean with ultrasound?

Because we are convinced that no single method alone delivers the best possible result.

That's why the Disco-Antistat Ultrasonic combines three cleaning technologies:

• 46-kHz ultrasound, which loosens even fine dirt from the grooves.

• Specially developed goat hair brushes, which gently support the cleaning process.

• An antistatic cleaning fluid, which removes dirt and simultaneously reduces static charge.

Our conclusion

When it comes to ultrasonic record cleaning machines, it's not about the biggest possible number.

What matters is how all components work together.

That's precisely why the Disco-Antistat Ultrasonic was developed as a coordinated complete system.

Because in the end, only one thing matters to us:

Clean records. Protected vinyl. More music enjoyment.
