Cleaning of silver by ultrasound

Ultrasonic cleaning of silver is a very high-quality and fast procedure that allows removing dirt of any origin from products of all sizes and shapes. Ultrasound removes dirt even in the most inaccessible places with which special active liquids failed. Very well cleans products with stones and those places where they are fixed, which can not be done by conventional methods manually at home. At the same time, it eliminates manual cleaning and makes it possible to replace expensive toxic cleaning liquids with inexpensive safe alkaline solutions and mixtures.

What is ultrasound?

Ultrasound is a sound wave whose frequency is in the range 16 kHz - 1 GHz and exceeds the threshold of human audibility. Application of ultrasound in a medium with liquids creates the effect of ultrasonic cavitation.

Important! Cavitation is an instant formation and destruction of small bubbles in liquids. It arises from the produced waves that have arisen from ultrasound, alternating between low and high pressure. From such exposure, the bubbles increase from microscopic size to large, after which they shrink and burst. The cavitation process, in combination with detergents or chemical agents, leads to active removal of impurities from the surface of the silver product to be cleaned.

What kind of contamination removes ultrasound?

As already noted above, silver cleaning by ultrasound allows removing all kinds of existing contaminants on decorations, cutlery, decor items.

Blacking and dirt on silver appear from various factors, such as:

• application of cream, lotion, perfume, soap cause a reaction to the metal;
• the natural fat release of the skin leaves its imprint, which form a thin film, it accumulates dirt and clogs into the indentations;
• corrosion products such as oxide film, rust, sludge;
• hard deposits formed on the surface of the product by solid particles of metal, abrasive, dust and fiber;
• deposit, which consists of resin, coke, ash;
• inorganic compounds - protein, sugar, starch, blood, salts.

Important! To clean the dirt from the silver and not to damage it, ultrasonic cleaning machines are used. Cleaning of silver in an ultrasonic bath Hagerty Sonic Cleaning Machine can be carried out and at home. With it, you clean your favorite products without making great efforts.

What is an ultrasonic bath?

An ultrasonic bath is a dishwasher in which a special liquid is poured and an object is placed that needs to be cleaned. When the device is turned on in the bath, oscillations occur at a frequency of 18 to 120 kHz in the ultrasonic range.

The device of such a device includes the following elements:

1. The generator generates electrical oscillations and amplitude modulation.
2. Transmitter converts vibrations electrical into mechanical( ultrasonic), they penetrate through the wall of the bath into the liquid to be cleaned.

Important! The generated vibrations penetrate deeply into all places on the object, even with a complex relief surface. This is the reason for the high-quality cleaning of silver in the ultrasonic bath.

After the procedure, the mud settles on the bottom of the bath. This method of cleaning is absolutely safe and takes only a few minutes, suitable for almost all types of non-porous stones.

Important! Before cleaning jewels with precious stones, it is recommended to consult a jeweler, so this procedure can lead to loss of shine of an expensive stone - this is the only drawback of this method.
