Specifications

What’s Included

• Best Built SD-180HT ultrasonic cleaner
• Stainless steel lid

Recommended Use

Effective for jewelry metals (gold, silver, platinum), set diamonds and hard gemstones (e.g., ruby, sapphire), and shop tools and parts. Ultrasonics do not remove tarnish.

Do Not Ultrasonically Clean

• Soft or porous stones: emeralds, opals, turquoise, pearls, amber, ivory, etc.
• Stones with many inclusions or fractures; heat- or shock-sensitive materials.
• Complete watches submerged in the tank. To clean metal bands, suspend the watch head above the solution and immerse only the bracelet using an appropriate holder in a basket.

Operating & Care Guidelines

• Do not run continuously; most cleaning occurs within the first 30 seconds.
• Keep solution level between 3/4 and 7/8 full; top off as needed.
• Always use a non-ammoniated, non-flammable ultrasonic cleaning solution. Pre-mix concentrates with water before filling the tank.
• Degas the bath: run the unit a few minutes before cleaning for best results.
• Use a basket: never place items directly on the tank bottom—this can damage transducers and void the warranty.
• To economize solution: after settling overnight, decant the clear top layer for reuse, strain the bottom, recover any valuables, dispose responsibly, and refill with saved solution plus fresh mix.
