Summer is here, and the underground garage is starting to get trendy. My Big White BMW X6 is not often driven and has been parked in the underground garage. During this time, I found black things on the ground under the car. I thought it was dirty on the ground, so I didn’t care too much. Later, there were more and more black things, so I turned on my flashlight to shine on it. The floor was full of dirty water and the bottom of the car was rusted.
It should be because the snow-melting agent was not washed clean. I drove to Harbin in winter. When I came back from Harbin, the highway was covered with snow water sprinkled with snow-melting agent, and the entire journey was nearly 1000 kilometers. At that time, the car was so dirty that I simply washed the car without deeply cleaning the chassis.
The chassis is rusty and dripping
Returning to Dalian from Harbin in winter, the car was filled with snow water with snow-melting agent
When I found that the chassis was rusty, I found a self-service car wash overnight. There is no car wash shop in Dalian that can not only lift the chassis but also wash the car, so I washed the car myself first to see the effect.
In a self-service car wash shop, the chassis was repeatedly washed with a high-pressure water gun, and the next day after washing the car, the car was parked in the sun to dry.
I parked the car back in the underground garage, observed it for a few days, and found that the chassis was still dripping, so I searched the Internet for a store that could lift the car and wash it.
This was the only store I found in all of Dalian and came here after making an appointment with the owner.
The entire rust removal and car washing process takes about 3 hours, cost: 400.
We’re at the door.
The store is very large
The boss first lifted the rear of the car and inspected it and found that the chassis was covered with salt grains. Fortunately, BMW’s chassis did not have much iron and the rust was not serious. The rust on the exhaust pipe was fine.

Get the trunk up
The boss began to remove rust, adding solvent to the bottle, spraying it on the chassis of the car, and then brushing it with a brush.
Repeat the previous step. After brushing the undercarriage clean, spray the undercarriage with high-temperature steam to make the stubborn salt and rust on the undercarriage fall off.
The rusted chassis is especially clean!

After cleaning the rear, he moved the front of the car and raised the front of the car to clean the chassis in front.
The steps are the same, first spray with solvent and brush, and then spray with high-temperature steam.

There is also a cat in the store
After the chassis was derusted, the outside of the car was washed and the engine compartment was also washed clean.
The entire rust removal and car washing process took about 3 hours. The boss said that my BMW chassis was not seriously rusty because there was not much iron. Previously, the chassis of other brands of cars was completely rusty, and it took several days to clean the car.
After cleaning, I felt light and thought the car was useless. Snow melting agent is too terrible. Normal car washing cannot wash the chassis completely. We can only find a shop that washes cars carefully and clean the chassis.
