Why Do You Need It?
  • Carbon deposits are residues produced by incomplete combustion of unsaturated olefins and colloids in engine oil and fuel at high temperatures during engine operation. Scorched substances, called "carbon deposits", what happens to the engine after severe carbon deposits? 1. The engine is difficult to start cold and shakes at idle speed. 2. The power of the engine decreases, and it is difficult to accelerate. 3. The fuel consumption of the engine increases. 4. The emission of exhaust pollutants increases.
  • 【Advanced Technology】The walnut sand carbon deposition cleaning technology, physical cleaning, pure natural material, will not cause any wear and tear on the interior of the auto, will not damage the electronic components in the auto, and will not affect the process accuracy of the cleaning part.
  • 【Safe and Harmless】Walnut sand is a kind of organic particulate matter. Even after cleaning, there is still a small amount of residue inside the engine, but walnut sand belongs to plants. After the high temperature combustion of the engine, these residual walnut sand particles will also be easily burned. It will cause any harm and loss to the material and operation of the auto engine.
Features
  • Large Capacity & High-Efficiency Cleaning, No Damage to Pipes】Utilizing a 1200W high-power motor, the powerful vacuum suction quickly removes media, effectively improving work efficiency.Also, walnut blasting features a 13L large-capacity stainless steel sand storage tank, allowing for continuous sandblasting without frequent refills. This cleaning method is a physical, harmless process, free of chemical pollution, and will not damage or corrode pipes, while providing superior cleaning results.
