Question 1

Is the cleaning solution included, and is it enough for long-term use?**

Accepted Answer

The machine comes with a small sample of cleaning solution to get you started. Many users recommend purchasing a dedicated ultrasonic cleaning fluid separately for optimal, long-term results, as the included amount is intended for initial use.

Question 2

What items can I safely clean with this machine, and what should I avoid?**

Accepted Answer

It's excellent for everyday items like eyeglasses, rings, silver jewelry, coins, and razors. However, avoid cleaning delicate gems (like opals or pearls), porous stones, plated items that may chip, and anything with glued components. When in doubt, check with the jeweler or manufacturer.

Question 3

How loud and powerful is it during operation?**

Accepted Answer

As noted in several online reviews, the cleaner does produce a noticeable humming sound and vibration. It's not silent, so it's best used in a kitchen or bathroom rather than a quiet office or bedroom. The vibration is a normal part of the ultrasonic process.

Question 4

What happens if the machine stops working? What is the warranty or return policy?**

Accepted Answer

The KECOOLKE cleaner is designed for reliable performance, as reflected in its overall positive system ratings. Should any issues arise, we recommend contacting the seller or KECOOLKE customer support directly through your purchase platform for assistance with warranty claims or returns, as policies can vary.

Question 5

Is this suitable for cleaning heavily tarnished or very dirty jewelry?

Accepted Answer

This cleaner is fantastic for regular maintenance and light soil. For heavy tarnish or caked-on grime, it works best as part of a process—you may need to pre-soak items or gently brush them afterward. It's a great time-saver but not a complete substitute for manual cleaning on extreme cases.
