Very easy, all you need to do is fill it with water (warm, distilled is best) and a drop of cleaning solution (optional).

Place item in and press the button.

Simple as that! Now enjoy the spotless shine!

A cleaning cycle takes just a few minutes, if you have extremely dirty glasses or other items.

You can also run multiple cycles back to back.

That is completely up to you and how much you use your glasses and jewellery. Every few days , once a week.

The state of your glasses will tell you when they need another dip in Spotless cleaning machine.

Absolutely! The ultrasonic waves reach deep into the tiny crevices removing trapped dirt and dust. Oil, grime, dirt are removed from your lenses through these waves as well.
