Introduction to the steps of removing carbon deposits from Audi walnut sand

1, we prepare a small bucket of ground walnut sand;

2, preparing a high-pressure nozzle, wherein one end of the high-pressure nozzle is connected with a high-pressure pump, and a feed pipe is connected with walnut sand;

3. We use gauze to block the nozzle of our engine (at this time to prevent walnut sand from entering the nozzle when washing);

4. We use a high-pressure nozzle to clean the parts of the engine with carbon deposits (note that the inside of the engine cylinder cannot be cleaned), and then vacuum with a vacuum cleaner;

We can clean one cylinder at a time.
