Dry Ice Cleaning Made Easy

Keeping surfaces and machinery clean is essential on a practical level to allow a machine to function well and not get clogged or overheat due to grime, dust, or other coated material. On an aesthetic level, keeping surfaces clean presents a better image for homeowners or owners of private or public property, and can reduce the chances of bacterial growth or allergies. Often, cleaning chemicals or blown air are involved in cleaning industrial and home surfaces, but another option for industrial cleaning and a cleaning solution in general is dry ice blasting. What is ice blasting? How is it good for fin fan cleaning and purging waste buildup in computers and other machines?

The Basics of Dry Ice

Fin fan cleaning and other cleaning jobs can be done with dry ice. What is it? Rather than being a form of standard water ice, dry ice is in fact frozen carbon dioxide, frozen at -79 degrees Celsius. Due this very cold temperature, dry ice will sublimate, or evaporate from a solid to a gas, if its container is not insulated properly. Dry ice, if allowed, will sublimate daily at a rate or 2 to 10%. This gas, CO2, is a natural trace gas found in the atmosphere, making up 0.05% of all air. Since dry ice is a very cold surface, this means that it must be handled with great care before fin fan cleaning or any other job. Its very cold surface can be a frostbite hazard to bare skin, and sublimated dry ice is a carbon dioxide poisoning hazard to workers. Therefore, anyone handling dry ice should wear protective gloves, long sleeves and pants, and goggles when handling this material, especially while moving blocks of it or breaking up blocks into smaller pieces. In a large freezer with dry ice blocks, a worker may even wear a full body protection suit against the cold and gas.

Using Dry Ice

Overall, three main types of hazards exist that can make surfaces or food unsafe for humans. Biological hazards include microorganisms such as bacteria, chemical hazards may be cleaning solvents or strong acids or bases, and physical hazards may include dirt, hair, dust, or other fine powders and materials. Pollen from plants may be categorized either as biological or physical; it can cause allergies, or clog the heat sinks and other delicate parts in a computer, for example. Large and small devices and surfaces, then, need cleaning, but sometimes, the wrong chemicals or their misuse can stain or corrode a surface and damage electronics. The solution is dry ice cleaning.

A dry ice blasting machine can be used on computers, car engines, kitchen surfaces, fan fin cleaning, and anything else where contaminants may be found. A dry ice blaster compresses air between 80 to 90 PSI and blasts pellets of dry ice at high speeds across any desired surface or area. One advantage of this cleaning method is that since no chemicals or powders are used, there is no mess to clean up and no chance of corroding or discoloring the affected surfaces. There is not even a mess to remove, since the dry ice, once exposed to warm or hot air and surfaces, will sublimate after use and leave behind no trace. Only the actual dirt being blasted away will be left, and this method even allows dry ice blasting to reach small or obscure areas or surfaces hard to reach with hand rags or other cleaning supplies, or wherever liquids would do a lot of harm.

What is more, dry ice is not conductive, so there is no electrical shock or short circuit hazard involved, according to Polar Clean, and dry ice is non flammable and non abrasive, so it will not scratch or erode any surface that it is used on, from metal to wood to delicate computer parts. When a business needs surfaces cleaned, such as fin fan cleaning or computers or vehicle engines, they can contact a cleaning company and request a crew with dry ice blowers. These devices may be hand held or be moved on wheels or carts, and with enough power, they can efficiently scour any surface of contaminants of any kind.
