What Not to Put in an Ultrasonic Cleaner

Items not built for immersion

Items that cannot be safely submerged or that contain non-waterproof parts should not be placed in a bath, especially a heated one.

Assemblies that trap water or that are not meant to be opened should be checked.

• Non-waterproof assemblies
• Parts that trap water
• Items damaged by heat

Delicate and incompatible materials

Certain fragile, soft or poorly bonded materials and some specialty surfaces can be affected by cavitation, heat or chemistry, and should be validated or excluded.

Some gems, settings and delicate finishes are not suited to ultrasound.

• Fragile or soft items
• Poorly bonded surfaces
• Unverified specialty finishes

Loose and hazardous items

Very loose parts that can fall into the tank and cause damage should be secured, and items that release hazardous material should not be processed.

Chemistry not intended for the bath should not be added.

• Loose fittings
• Hazard-releasing items
• Unapproved chemicals

Confirm before cleaning

Confirm the material, chemistry, temperature and frequency with a representative item, and use a basket or enclosure to keep parts managed.

Industrial parts are generally validated before production.
