Ultrasonic cleaning uses high-frequency sound waves (45,000 Hz) to create millions of microscopic bubbles in water through a process called cavitation. These bubbles rapidly implode, creating gentle yet powerful scrubbing action that reaches into every groove, crevice, and hard-to-reach area of your dental devices. This removes plaque, stains, protein buildup, and debris that manual brushing and soaking can't effectively eliminate. Combined with UV-C light sanitization, the Petal Ultrasonic Combo delivers professional-grade cleaning in just 5 minutes.

The Petal Ultrasonic Combo is perfect for cleaning a wide variety of dental devices and orthodontic appliances, including: clear aligners (including Invisalign® and NewSmile®), wire retainers, plastic retainers, sports mouthguards, night guards for teeth grinding, dentures, partial dentures, bridge work, and orthodontic retainers.

Absolutely! Ultrasonic cleaning is one of the safest and most effective methods for cleaning clear aligners, including popular brands like Invisalign® or NewSmile®. In fact, many orthodontists recommend ultrasonic cleaners because they remove buildup without scratching or clouding the plastic material.

The ultrasonic cleaner works effectively with just water alone, but we highly recommend using the Petal Pods for optimal results. The pods are specially formulated to enhance the ultrasonic cleaning action by breaking down stubborn protein buildup, eliminating odor-causing bacteria, and leaving your devices with a fresh, clean scent. Each pod is pre-measured for the perfect concentration, ensuring consistent results every time. Your purchase includes a FREE 1-month supply, and you can subscribe for automatic refills every 2 months at 35% savings.

The Petal Ultrasonic Combo offers two cleaning cycle options: a 5-minute quick clean cycle for daily maintenance and light cleaning, and a 10-minute deep clean cycle for more thorough sanitization and stain removal. Most users find the 5-minute cycle perfect for daily use, while the 10-minute cycle is ideal for heavily stained devices or weekly deep cleaning. The device automatically shuts off when the cycle is complete, so you can simply set it and forget it.

For optimal hygiene and to prevent bacteria buildup, we recommend cleaning your dental devices daily if you wear them regularly. The 5-minute quick clean cycle makes daily cleaning effortless and convenient—simply clean them each morning or evening as part of your routine. For devices worn less frequently, such as night guards or sports mouthguards, clean them after each use. Deep cleaning 2-3 times per week with the 10-minute cycle will help maintain their appearance and eliminate stubborn stains.

Yes! UV-C light has been scientifically proven to eliminate 99.9% of bacteria, viruses, and other harmful pathogens. UV-C light works by damaging the DNA and RNA of microorganisms, preventing them from reproducing and effectively killing them. This same technology is used in hospitals, dental offices, and medical facilities worldwide for sanitization. The Petal Ultrasonic Combo's UV-C light penetrates your dental devices during the cleaning cycle, ensuring they're not just visibly clean but truly hygienic at a microbial level.

Maintaining your Petal Ultrasonic Combo is simple. After each use, empty the water from the tank and wipe it dry with a soft cloth. Once a week, wipe down the interior of the tank with a damp cloth to remove any residue. Allow the unit to air dry completely with the lid open between uses to prevent moisture buildup. The stainless steel tank is resistant to staining and corrosion, making maintenance effortless. Never submerge the entire unit in water, only the interior tank should contain water during cleaning cycles.

The Petal Ultrasonic Combo operates quietly at a low hum during the cleaning cycle. While you'll hear the ultrasonic waves working (a gentle buzzing sound), it's not loud or disruptive. Most users find they can easily use the cleaner in their bathroom or bedroom without disturbing others. The noise level is comparable to an electric toothbrush, noticeable but not bothersome.

We strongly recommend using only our Deep Clean Pods or plain water in the Petal Ultrasonic Combo. Denture tablets, bleach, harsh chemicals, or other cleaning solutions can damage the ultrasonic mechanism, corrode the stainless steel tank, or leave residue that affects performance. Our Petal Cleaning Pods are specifically formulated to work synergistically with ultrasonic cleaning technology, providing optimal results without risking damage to your device.

Manual brushing, while better than nothing, has several limitations: it can only clean surfaces you can physically reach with the bristles, it can create microscopic scratches that harbor bacteria, it requires significant time and effort, and it's easy to miss areas or apply inconsistent pressure. Ultrasonic cleaning reaches 100% of surfaces including tight spaces between wires, deep grooves, and textured areas. The cleaning action is uniform and consistent across the entire device, and it's completely effortless—no scrubbing required. Most importantly, the combination of ultrasonic waves and UV-C light provides a level of sanitization that manual brushing simply cannot achieve.
