Kirmuss Audio - KA-RC-1 - Ultrasonic Record Restoration System

Hear Your Records the Way They Were Meant to Sound!

Every pop, crackle, and hiss you hear isn't just wear and tear — it's decades of dust, mould, fingerprint oils, and invisible manufacturing residue sitting deep inside your record's grooves. Standard cleaning methods just push it around. The Kirmuss Audio KA-RC-1 Ultrasonic Record Restoration System actually removes it.

This isn't a record cleaner. It's a record restorer — and there's a big difference.

Why Your Records Need More Than a Brush

When a vinyl record is pressed at the factory, a release agent is baked into the groove itself. Every time your stylus runs through that groove, it heats up that residue, welding dust particles deeper into the surface. Over time, this builds up — silencing the detail, warmth, and dynamics the artist intended. Wiping, vacuuming, or rinsing with cleaning fluid can't touch it.

The KA-RC-1 can.

The Science Made Simple

Using 35kHz ultrasonic cavitation — the same technology used in professional laboratory and medical equipment — the KA-RC-1 creates millions of microscopic bubbles that collapse with enormous energy directly inside your record grooves. This dislodges and lifts out contaminants that nothing else can reach.

But Kirmuss goes further than standard ultrasonic cleaners. A specially developed ionising surfactant spray (included) is applied to each record before cleaning. This temporarily reverses the electrical charge of the record, attracting the ultrasonic plasma wave directly into the grooves — something no other system on the market does. The result is true groove restoration, not just surface cleaning.

A passive 70kHz resonance works alongside the primary frequency to evenly distribute the cleaning energy across the record, protecting it from damage while maximising results.

What Makes the KA-RC-1 Different

• Patented record suspension system — records float safely in the bath, properly spaced. No skewers, no squeezing, no risk of label damage
• Clean up to 4 records at once — process two LPs, one 45, and one 78 rpm record in a single session
• Works on all record sizes and speeds — 12", 7", 10", 33⅓, 45, and 78 rpm
• Removes what others leave behind — release agents, micro-welded dust, mould, fungus, and residue from previous cleaning products
• Visible results — you can actually watch the contamination being lifted from the grooves as you work
• PVC-safe chemistry — the included surfactant is water-soluble, antibacterial, antifungal, and completely safe for your vinyl
• ETL (US) and CE (EU) safety certified
• Endorsed by Stereophile Magazine — Michael Fremer called it "Enthusiastically Recommended"
