The Degritter RCM MARK II: Unleashing the true potential of your vinyl records

The vinyl revival is no longer a marginal phenomenon. In 2024, vinyl record sales continue to grow, attracting both nostalgic listeners and new audiophiles. However, owning quality vinyl isn’t enough: proper maintenance determines sound quality and longevity, which is where the Degritter RCM MARKII comes in !
The consequences of poor maintenance
Problem | Impact on Listening | Impact on Equipment |
Dust in grooves | Crackling, hissing | Premature stylus wear |
Fingerprints | Sound distortion | Residue accumulation |
Manufacturing residues | Parasitic noise | Microscopic scratches |
Static electricity | Dust attraction | Clicking during playback |
Degritter: estonian innovation revolutionizing vinyl cleaning
Degritter is an Estonian company founded in 2016, which began commercializing its machines in 2019. The brand distinguishes itself through its premium approach, offering machines that integrate seamlessly into high-end Hi-Fi systems while democratizing professional ultrasonic technology.
How does ultrasonic technology work?
RCM MARKII‘s ultrasonic technology operates through a 4-step process:
- Wave generation: transducers emit high-frequency waves
- Microbubble creation: waves form cavitation bubbles in water
- Controlled implosion: bubbles implode, creating high-pressure micro-jets
- Deep cleaning: jets dislodge impurities from microgrooves
Why use high frequency (120 kHz)?
Higher frequency generates much smaller cavitation bubbles (2.5 µm) than low frequency (8 µm). This microscopic size is essential, as the bottom of a vinyl microgroove measures only one micron.

RCM MARK II: a user-focused machine
Component | Specification | Advantage |
Transducers | 4 units at 120 kHz | Uniformly distributed power |
Power | 300W average, higher peaks | Most powerful per liter of water on market |
Tank | 1.4 liters | Optimized for 33 RPM records |
Materials | Anodized aluminum | Premium resistance and aesthetics |
Filtration | Continuous active system | Prevents dirt redeposition |
Drying | Variable filtered air | 50-70 dB, customizable time |
- Intelligent temperature control: The machine monitors water temperature. If it exceeds a certain threshold (35°C), automatic cooling cycles are triggered to prevent vinyl damage.
- Active filtration system: An active filtration system continuously pumps water through a replaceable filter, ensuring removed dirt doesn’t redeposit on the record.
- Customizable drying: Drying occurs via filtered airflow. Users can adjust fan speed and drying time to minimize noise (between 50-70 dB) and reduce static electricity.



How and when to use your Degritter
RCM MARKII usage guide
Preparation
- Fill reservoir with distilled water (mandatory)
- Add 2-3 ml of Degritter cleaning fluid
- Check filter cleanliness
- Turn on and let preheat for 2 minutes
Cleaning
- Insert record without forcing
- Select appropriate program
- Press START
- Machine automatically manages: soaking → cleaning → drying

Recommended cleaning programs
Record Type | Program | Duration | Usage |
New vinyl | Quick | 5 min | Manufacturing residue removal |
Personal collection | Medium | 10 min | Regular maintenance (every 10-20 plays) |
Very dirty used | Intensive | 15 min | First use or neglected records |
Restoration | Double intensive | 30 min | “Lost” records with multiple passes |
Maintenance frequency by usage
- Active collector: cleaning after purchase + maintenance every 15 plays
- Occasional listening: initial cleaning + maintenance every 25 plays
- Intensive use: cleaning every 10 plays + monthly check
- Precious vinyl: preventive cleaning before each critical listening session
Results that transform listening
Users consistently report these improvements:
Noise Reduction
- Complete elimination of dust-related crackling
- Disappearance of surface hiss
- Significant reduction of background noise
Sound quality
- Restored dynamics: better loud/soft differentiation
- Improved clarity: cleaner instrumental separation
- Expanded soundstage: impression of space and depth
- Revealed details: previously masked micro-details
“ I am very satisfied with this device’s performance. Records find or rediscover pure sound. Previously, I had a Humminguru. It did the job very well, but the Degritter is above: records washed several times with the Hummi still improved with the Degritter. More silence, fewer clicks or clacks… Moreover, the Degritter works in automatic mode, you insert a record, press the button and that’s it until the next record. Again, even if it’s not essential, it’s more practical than the Hummi. In short, impossible now to listen to an LP without it going through the Degritter. Only the price might make you hesitate, I myself took a long time to take the plunge. But I don’t regret it ”
