How to clean blackened brass


Brass, a material used in a wide range of objects, often darkens and loses its original lustre over time. 

Fortunately, ultrasonic washers are a powerful tool that can help you clean blackened brass efficiently and without damaging the parts.

 Join us as we explore practical tips for using ultrasonic washers to clean brass.

How cleaning with ultrasonic cleaning machines works

Ultrasonic washers use high-frequency sound waves to remove dirt, rust and other contaminants from surfaces.

In the case of blackened brass, these machines can be particularly effective, as their vibrating action penetrates into the layers of dirt and restores the original shine to brass.

Steps to clean blackened brass with an ultrasonic washer


Before you start, make sure you have all the necessary elements. 

Fill the ultrasonic washer with lukewarm water and add a mild detergent specifically designed for this type of cleaning.

Disassembly (if possible)

If your blackened brass parts are removable, it is advisable to separate them before cleaning. 

This will allow the water and ultrasonic waves to reach all areas more efficiently.


Place the brass parts in the basket of the ultrasonic washer, making sure not to overload it. It is important that the parts do not touch each other to avoid possible damage.


Turn on the ultrasonic washer and select the appropriate time and power for cleaning the brass.

Cleaning process

During the cleaning cycle, the ultrasonic waves will generate small bubbles that implode, releasing energy and removing dirt from the blackened brass.

This process can take several minutes, depending on the degree of blackening.

Rinsing and drying

Once the cleaning cycle is complete, remove the parts from the washer and rinse them with warm water to remove any detergent residue.

Be sure to dry the parts carefully with a soft, absorbent cloth to prevent water spots from forming.
