What is the use of dry ice blasting for cars?
2 Answers
Dry ice blasting cleaning can solve the problem of carbon deposits in cars. Here is some introduction about dry ice cleaning: 1. Dry ice cleaning uses high-pressure gas to blast dry ice particles onto the surface of the object being cleaned. The rapid change in momentum causes the dry ice to melt quickly. Due to thermal expansion and contraction, the high-temperature piston is enveloped by dry ice particles (-78.5°C), and the temperature difference rapidly separates the carbon deposits on the surface, causing them to quickly become brittle and break apart. 2. After dry ice particles penetrate the cracks in the dirt, their volume rapidly expands 600 to 800 times, stripping the dirt from the surface of the object. The dirt is then carried away by the gaseous CO2, causing no damage to the surface of the object being cleaned, especially metal surfaces, and does not affect the smoothness of the metal surface.
I've always thought that dry ice blasting on cars is mainly used for professional cleaning, especially for stubborn stains or grease. The dry ice itself is extremely cold and can quickly freeze the dirt, then directly sublimate into gas under high-pressure blasting, leaving no water marks or chemical residues. When I worked in the workshop, I often used it to clean carbon deposits in the engine bay or adhesive residue in door gaps. It's much faster than traditional scrubbing and doesn't damage the surface of the parts. For older cars, it can restore them to a near-new condition, saving the hassle of disassembly. Of course, this isn't a DIY job—it requires professional equipment and experience to avoid personal injury. Cost-wise, it's more expensive than regular car washing, but in the long run, it helps preserve the vehicle's value. If you find tough stains on your car, it's worth considering professional services, but always pay attention to safety measures and wear protective gear.
