diamond cleaner

Most listings say these cleaners are suitable for precious metals and stones such as gold, platinum and diamonds, and for various precious and semi‑precious stones. Some liquid formulas also list pearls and other delicate gemstones as cleanable, but a few product notes explicitly warn against using certain cleaners on pearls, coral or opal. Always check the product details for any exclusions before cleaning.

Ultrasonic cleaners use high‑frequency sound waves to create microscopic bubbles (cavitation). When those bubbles collapse, they dislodge dirt, oil and buildup from crevices and settings, delivering a deep but gentle clean without scrubbing.

Timer and cycle options vary by model. Some units provide a few preset cycles (examples in listings include 5 or up to 18 preset times), with common quick/deep settings such as about 5 minutes and 10 minutes. Overall timer ranges reported in listings run from roughly 90 seconds up to about 30 minutes, depending on the model.

Most ultrasonic cleaners operate with simple one‑button or digital timer controls. Many models clean effectively using only water, though product descriptions often note that adding a compatible ultrasonic cleaning solution can improve results for heavy soils or specific materials.

Several listings explicitly warn against using certain liquid or gel cleaners on delicate materials such as pearl, coral and opal. Pearl is named as not recommended in multiple listings. Check the product notes for any model‑specific exclusions before cleaning delicate items.

Typical tank sizes reported in listings are around 20 oz (about 600 ml) and around 400 ml. Note that some product bullet points use inconsistent units (for example, one listing shows “400 ounces” in its details), so verify the listed capacity and units on each product page.

Common accessories include a dipping/cleaning basket or tray and a small brush. Many machines also include a watch holder/watch stand, plus supporting items such as a quick‑start guide and a one‑year warranty in some kits.

Listings commonly show frequencies in the ~40–48 kHz range (examples include 40,000 Hz, 42,000 Hz and 48 kHz). Power figures cited for different models include values around 35–40 watts.

Liquid dip cleaners can be very fast (one listing claims “cleans in 30 seconds”). Ultrasonic cycle times reported in listings range from about 90 seconds up to 30 minutes, with common quick/deep presets around 5 and 10 minutes.

Liquid jewelry cleaners are commonly sold in about 8 fl. oz. (236 ml) bottles. One listing notes enough solution for over 80 ten‑drop cleaning batches; gel stick sizes or per‑stick use counts were not specified in the available details.
