You’ve unboxed your new Creworks Ultrasonic Cleaner, filled the tank, and you’re ready to watch that grime vanish. But before you hit “Start,” there’s a button you might be ignoring: DEGAS.
If you’ve ever wondered why your cleaning results are inconsistent—sometimes sparkling, sometimes “just okay”—the secret usually lies in the air you can’t see.
The Science: What is “Degassing”?
When you fill your tank with fresh tap water, it’s packed with dissolved oxygen and gasses. In the world of ultrasonic cleaning, air is the enemy.
Ultrasonic cleaning works through cavitation: millions of microscopic vacuum bubbles forming and imploding against your item. However, if the water is full of dissolved air, those cleaning bubbles act like tiny “pillows.” Instead of imploding with force to scrub away grease, they just bounce off.
Degassing is the process of stripping that air out of the liquid so the bubbles can do their job at 100% power.
How to use Degas Mode like a Pro
Most Creworks digital models feature a dedicated Degas button. Here’s the “Creworks Workflow” for the best results:
- Fill & Mix: Add your water and cleaning solution (we recommend a 1:10 ratio for most jobs).
- Heat it Up: Set your target temperature. Warm water (around 40°C–60°C) degasses much faster than cold water.
- Run Degas: Press the Degas button. You’ll hear the machine cycle on and off in a rhythmic “pulse.” This pulse allows air bubbles to rise to the surface and escape rather than staying trapped in the solution.
- The Visual Cue: You’ll know you’re ready when the “hissing” sound of the machine becomes sharper and the surface of the water looks like it’s “shimmering” rather than just swirling.
Creworks Tip: Always degas for 5–10 minutes every time you change the water. If you don’t have a dedicated button, simply run a standard cycle for 10 minutes without any items in the basket.
Three Times You Must Degas
While we recommend it for every cycle, degassing is mandatory in these scenarios:
- Fresh Water Changes: Tap water is the “airiest” right out of the faucet.
- Adding New Chemicals: Introducing soap or specialized concentrates creates new air pockets.
- Intricate Parts: If you’re cleaning carburetors or watch movements, you need maximum cavitation to reach those tiny, “blind” holes. Without degassing, air stays trapped in those holes, and the cleaning waves never actually reach the dirt.
The Result?
By taking ten extra minutes to degas, you aren’t just “washing” your items—you’re scientifically optimizing your machine. You’ll notice faster cleaning times, a more “surgical” shine, and less wear and tear on your machine’s transducers.
