Caribbean Gem Ultrasonic Cleaner Solution Concentrate 2×237 ml — Plant-Based, Highly Concentrated

Caribbean Gem Ultrasonic Cleaner Solution Concentrate is a highly concentrated, plant-based cleaning fluid designed to restore shine to jewellery, eyewear, watches, and small metal parts when used in ultrasonic machines.

This two-bottle pack (2 × 8 oz) of USA-made concentrate turns ordinary water into a powerful cleaning bath for home or professional ultrasonic units. Formulated from plant-derived ingredients with a pleasant Caribbean-inspired scent, the solution is non-abrasive and intended for routine cleaning of precious metals, gems, eyeglass frames, and accessories. A single capful diluted per 20 ounces of water delivers many refills, making it economical for repeated use.

How should I use this concentrate in my ultrasonic cleaner?

Measure one capful of Caribbean Gem concentrate into 20 ounces of warm water inside your ultrasonic tank, then run the recommended cycle for your device and items. For delicate pieces, shorter cycles or lower temperatures help protect settings and porous stones. After cleaning, rinse items in clean water and dry with a soft cloth to avoid spotting.

• Mix ratio: 1 capful per 20 fl oz (approx. 1:80 dilution).
• Use warm—not boiling—water to improve cleaning action.
• Short cycles for fragile items; longer cycles for heavy tarnish.
• Rinse and pat dry after ultrasonic cleaning.

What materials and items are safe to clean with this solution?

The concentrate is formulated to be plant-based and non-abrasive, suitable for most common jewellery metals (gold, sterling silver, platinum), eyeglass frames, watches (bands and metal cases), coins, and small metal tools. Avoid using ultrasonic cleaning on loose or treated pearls, soft porous stones (like opal or turquoise), and items with loose settings; check manufacturer guidance for sensitive pieces.

• Safe: gold, silver, stainless steel, hard gemstones, eyeglass frames.
• Avoid: porous stones, glued items, delicate enamel or certain watch faces.
• Test a small inconspicuous area when unsure.
• Use a soft brush for stubborn grime after machine cycle.

How many cleanings will two 8 oz bottles provide and is it cost-effective?

Each 8 oz bottle yields many refills because the concentrate is highly concentrated; the manufacturer estimates up to 74 machine refills from the set under normal use. Diluting one capful per tank means the product stretches considerably, reducing per-cleaning cost compared with ready-to-use formulations. That makes it practical for hobbyists, optical shops, and small jewellery businesses that need frequent maintenance cleaning.

• Two 8 oz bottles packaged for extended use.
• Estimated total refills: up to 74 (varies by cap size and usage).
• Concentrate format lowers storage volume and shipping cost.
• Good option for frequent home and light-professional use.

Does the product leave a scent or residue, and how should I store it?

Caribbean Gem’s formula includes subtle banana and coconut notes for a fresh scent; when diluted and rinsed properly, it should not leave noticeable residue on cleaned items. Store the concentrate tightly closed in a cool, dry place away from direct sunlight to preserve fragrance and efficacy. Keep out of reach of children and follow disposal guidance on the label.

• Light tropical fragrance—rinse items to remove any trace.
• Store sealed in a cool, dry location away from heat.
• Avoid freezing; keep away from children and pets.
• Follow local disposal rules for cleaning solutions.
