1. Best Ultrasonic Retainer Cleaner 

When it comes to the best ultrasonic retainer cleaner, you need something designed specially for dental appliances. Research shows ultrasonic cleaners are highly effective at eliminating bacteria, viruses, and pathogens that accumulate on oral appliances.

• The 200 ml capacity is perfectly sized for retainers and aligners.

But here's what makes it special: the built-in Germicidal Ultraviolet-C (UVC) light function. This UV technology sanitizes your dental appliances without water or chemicals, giving crucial disinfection for the items that go in your mouth daily.

2. Best Ultrasonic Jewelry Cleaner

For jewelry cleaning, you need enough power and capacity to handle different pieces while being gentle enough not to damage the precious metals and stones.

Creworks 60W Ultrasonic Cleaner with 100W Heater - $53.99

That’s why the Creworks 60W Ultrasonic Cleaner with 100W Heater, the best ultrasonic jewelry cleaner in our books, uses frequencies between 40-48 kHz for optimal cleaning balance. Originally $59.99, this 60W ultrasonic cleaner gives some incredible value for serious jewelry cleaning.

• The 2L capacity means you can clean multiple pieces at once, while the 40 kHz frequency provides perfect cleaning action without the risk of any damage.
• The 100W built-in heater makes the cleaning process more efficient by loosening dirt and grime more effectively, especially important for jewelry that has collected oils, lotions, and everyday grime over time.
• The dual knob design gives precise control over the temperature range of 70-175°F and a cleaning time of up to 30 minutes.
• This control is crucial because different jewelry types require different cleaning approaches based on what and how they’re made.
