Cleaning with dry ice has proven to be an extremely effective method of removing contamination in the electrical industry. Dry ice, which is in the form of frozen carbon dioxide (CO₂), offers a number of advantages that make it particularly suitable for cleaning sensitive electronic components.
Dry ice cleaning is often applied by spraying or blasting the dry ice pellets onto the surfaces to be cleaned. The extremely low temperatures of dry ice (-78.5 °C) cause contaminants such as dust, oil and other residues to contract and detach from the surface. This often happens without any risk of mechanical damage, which is particularly important in the electrical industry.
The low abrasiveness and ability to remove even the finest particles make dry ice an ideal choice for cleaning circuit boards, cables, housings and other electronic components.

One of the key advantages of dry ice is its non-conductive property. This means that, unlike water or other liquids, it cannot cause electrical conduction. In the electrical industry, where electronic components are often very sensitive and have short power lines or tight designs, it is of utmost importance that no moisture or conductive residue is left behind. Dry ice cleans by sublimation, i.e. by immediately turning into gaseous carbon dioxide on contact with the ambient air, without leaving behind any liquid that could lead to corrosion or short circuits.
In addition to the technical advantages, dry ice cleaning is also more environmentally friendly than many traditional cleaning methods. Because dry ice is derived from CO₂, which is a waste product in many industrial processes, the use of dry ice has a lower environmental impact. It also eliminates the need for chemical cleaning agents, which can often be harmful to the environment and the health of workers. Cleaning with dry ice leaves no chemical residue, which means that the cleaned parts can be put into operation immediately, without further post-treatment or drying times.
Another practical advantage of dry ice cleaning is the efficiency and speed with which it can be carried out. In an industry where downtime is costly, fast and thorough cleaning with dry ice allows machines and systems to be back up and running quickly.
One of the main applications is dry ice cleaning of assemblies and control boxes, where dust, dirt and other contaminants can often lead to malfunctions or even breakdowns. With dry ice, companies can ensure that their products remain in optimal condition, extending the life of the equipment and reducing maintenance costs.
Dry ice cleaning is also ideal for cleaning electrical insulators, transformers and motors. These components are often difficult to access and require thorough cleaning to ensure their functionality. The precise application of dry ice makes it possible to remove particles and deposits without damaging the sensitive material or leaving any residue behind.
Another significant advantage of dry ice cleaning is the time it saves. Compared to conventional cleaning methods, where appliances often have to be dismantled or cleaned in complex processes, dry ice cleaning enables fast and effective cleaning on site. This minimizes production losses and downtimes.
Dry ice cleaning offers an innovative and practical solution in the electrical industry that is both safe and effective. The non-conductive properties of dry ice, coupled with its ability to remove even the most stubborn contaminants, ensure that companies can manufacture their products to the highest quality, helping them to remain competitive in an increasingly technical market.
