What can I clean in a 15 L ultrasonic cleaner?

The tank volume suits batches of metal parts: carburetors, injectors, bolts, tools, gun parts and similar hard items. It is not meant for delicate jewelry, soft stones or anything heat-sensitive.

Does the heating function matter?

Yes. A heated bath softens grease, oil and carbon so the ultrasonic action lifts them faster. Many parts that stall in a cold bath come clean in a warm one.

What solution should I use?

Use a cleaning solution made for ultrasonic tanks and dilute it as the maker directs. Skip flammable solvents and strong acids, which can damage the stainless tank or create hazards when heated.

Is 304 stainless steel good for this?

304 is the standard grade for ultrasonic tanks. It resists rust and most water-based cleaning solutions, so the tank holds up to repeated heated cycles.

How is it different from a small benchtop cleaner?

The main difference is volume. A small unit cleans one or two items at a time; this one takes a batch, which saves cycle time in a shop but needs more bench space and more solution per fill.
