What are the procedures for car wash maintenance, and what are the processes for professional car wa

There are four processes for a professional car wash.

The first step in cleaning is to remove the dust from the car, sweep away the dirt from the large pieces, and then use a vacuum cleaner to remove the dust from the carpets and the crevices of the seats.

Clean the control room:

The dashboard and steering wheel are mostly made of plastic and leather goods, which are easy to adhere to dust, but also easy to clean. It must be noted that due to the long-term exposure of the dashboard to sunlight, it is prone to aging and brittleness. Therefore, it is best to choose the best surface to spray wax, and then wipe it clean with a clean cotton cloth, so as to protect the dashboard well.

Clean empty air conditioning ducts:

Remove the air outlet, insert the air cleaner into the air duct, and spray an appropriate amount of air cleaner. Then turn off the air outlet, open the air circulation, start the engine, and idle for about 10 minutes. Clean the air filter at the same time.

Cleaning of seats:

When cleaning the seat of the flannel or its fabric, spray the high-efficiency foam cleaning solution on the dirt, stop for a minute, and carefully wipe it repeatedly with a clean, dry towel until the stain is removed.

Summary. Hello dear, it is a pleasure to serve you <>

The correct process of car maintenance is: change the oil, oil filter, gasoline filter, air filter; Check whether the position of the liquid level of the automobile coolant meets the regulations; Check the position of the brake and clutch fluid level; Check whether the oil level of the steering power tank meets the regulations, and check whether there is oil leakage at the interface of each oil pipe of the system; Check the liquid level of the battery and the liquid level of the glass cleaning agent tank.

The correct process of car maintenance is: change the oil, oil filter, gasoline filter, air filter; Check whether the position of the liquid level of the automobile coolant meets the regulations; Check the position of the brake and clutch fluid level; Check whether the oil level of the steering power tank meets the regulations, and check whether there is oil leakage at the interface of each oil pipe of the system; Check the liquid level of the battery and the liquid level of the glass cleaning agent tank.

Extended information: China's new national standard "Terms and Definitions of Automobile and Trailer Types" (GB T3730 1-2001) defines a car as follows: a non-track vehicle driven by power with 4 or more wheels, mainly used for:

carrying persons and/or goods; towing vehicles carrying people and/or goods; Special Purpose.

The basic maintenance process is divided into five items: external maintenance, engine maintenance, tire maintenance, battery maintenance, and air conditioning maintenance. The specific maintenance process: 1. Regularly replace the new spark plug 2, regularly replace the air filter 3, and overhaul the cooling system on schedule.

1. Replace the spark plug with a new one regularly. Check whether the spark plug wire is cracked or burned out, whether the insulation is broken, and the cracked high-voltage wire will increase fuel consumption because it cannot conduct sufficient voltage to the spark plug. Confirm that the ignition timing is adjusted according to the manual.

2. Replace the air filter regularly. Replace the fuel filter at the time required by the instructions. Make sure that the mixture of idle speed and carburetor is correctly adjusted according to the instructions.

Use a motor oil with a defined viscosity to reduce friction. Use rear axle and transmission lubricants with defined viscosity.

3. Overhaul the cooling system on schedule. Check whether the water tank cover is cracked, whether the liner is damaged, if the water tank cover is not tightly closed, the cooling system will not work properly. Confirm that the thermostat is working properly, if the thermostat is sluggish and does not open for a longer time, it will also delay the engine heating up, and the fuel consumption of a cold engine is equal to twice that of a warm engine.

First, the correct steps to wash the car:

1. Use clean water to rinse hard particles such as floating sand on the surface of the car.

2. Configure the car wash wax cleaner according to 1:150, load it into a high-pressure foam spray can and spray it all over the car.

3. Use a car wash sponge to wipe the dirt of the whole car, and then rinse off the foam of the whole car with clean water.

4. Finally, use a clean dry towel to dry the whole car.

Second, car washing needs attention

1. Do not wash the car in high temperature and scorching sun, the high temperature and cold water of the body will cause uneven heat and cold and damage the car paint.

2. Do not use a high-pressure water gun to rinse and wipe the body directly, because the body dirt will have hard particles, and direct cleaning will scratch the car paint.

3. Don't think that you don't need to wash the car in the rainy season, the washing power of the rain can't wash off the dirt of the body at all, and the long-term adhesion of the dirt will be combined with the car paint. Moreover, modern rainwater is weakly acidic, and it will corrode the car if it is not washed for a long time.

4. Don't wash the car too often, it is not recommended to wash the car more than 4 times a month, too often will also damage the surface of the car paint.

5. Do not use household products such as detergent to wash the car, ordinary detergents are generally acidic and alkaline, which will corrode the whole car paint and aging rubber. It is recommended to use special car wash wax as a cleaning agent, such as Medigy, Chefu, Turtle, 3M and other big brand products.

A car wash cleans the dirt from the surface of the car, and it also maintains the car. Below, let's take a look at the basic steps of car washing.

When the customer arrives, the professional will go to the reception, let the customer wait indoors, and drive the car to the washing place. Then use a water gun to rinse the car, this step can wash off the dust and sediment on the surface of the car.

After the car flushing step is completed, start to foam the paint surface of the car, which is mainly to decompose some dirt on the surface of the car that is difficult to wash off with professional car wash foam.

After the foam is finished, you can scrub the car, usually with a sponge. Mainly scrub the painted surface of the car and places such as wheel belts.

After the car wiping steps are completed, use a wiper to scrape off the moisture on the car, and then use a towel to wipe the paint off the car.

Then use a cleaning towel to clean the interior of the car, mainly the pedals of the car, around the door cracks, floor mats, etc.

1. Wash away the sediment first.

When cleaning with a high-pressure water gun, use a high-pressure water gun to wash the sediment off the surface of the body from top to bottom. Then wash the rear of the car, and finally the lower part. Take care to wash the wheels and brake discs, fenders and grids from mud.

2. Spray car wash liquid.

After the high-pressure water gun rinses the car body, it is time to liquidate the car, splash the car wash liquid evenly on the body, and then use a multi-functional high-pressure car wash machine or manually wipe the car wash liquid evenly, do not use laundry detergent, soap, etc.

3. Wipe the body with a car wash sponge.

It is to wipe the car wash liquid on the car body with a car wash sponge, and then use a high-pressure water gun to rinse the car clean.

4. Remove stains.

Carefully remove some of the remaining stains on the body, which requires the use of descaling water in conjunction with it.

Note: When removing stains, wipe them in a direction perpendicular to the car's driving.

5. Wipe the body moisture dry.
