Q&A
Q: Can I clean rings, necklaces, or dentures?
A: This machine is specifically designed for
retainers/orthodontic aligners, and we do not
recommend cleaning other items.
Q: Why is the blue light flashing?
A: Continuous 20-minute operation triggers a
5-minute overheating protection.
Q: Why does the device adopt the specialized USB
port instead of the universal Type-C charging
port?
A: A specialized charging port is adopted because
the standard USB port commonly used for
smartphones is prone to oxidation when
exposed to water. However, this device (unlike
smartphones) frequently comes into contact
with water, so a more durable design is chosen
to extend the product's service life.
Q: Can I use dish soap, toothpaste or other viscous
cleaning agent for better cleaning effect?
A: No.The viscous cleaning agent may interfere
with the operation of this ultrasonic retainer
cleaner, which will reduce the cleaning effective-
ness. It's recommended to use the Coslus
specialized effervescent tablet to achieve the
best result.
