The raw material of walnut sand is a walnut shell, which is made and synthesized through strict screening and classification and multiple processes after the walnut shell is broken. It is a walnut extract and belongs to metal polishing media. It has the characteristics of high hardness, high-pressure resistance, and wear resistance, and the surface is microporous. It has strong adsorption and sewage interception ability, no corrosion and no pollution. Walnut shell is a natural and non-chemical raw material, so using walnut sand as an abrasive will not damage the surface of the workpiece, and using walnut sand to clean auto carbon deposition will not damage the engine, the cleaning effect is remarkable and the cost is low.
There are some hydrocarbon olefin residues attached to the engine intake, cylinder when the fuel burns in the engine not completely. It residues change into a hard black shell in high-temperature conditions, called carbon deposition.
Why need Clean Carbon Deposition?
Carbon deposition will decrease the air-fuel ratio, cut down engine output power, increase fuel consumption, engine drastic shake on idle status all the thing will hurt the engine deeply. So normally we should clean carbon deposition after every 40000-50000 kilometer trip.
