1. Prepare tools and materials
Prepare the car paraffin washing gun, PA foam pot, water wax car washing liquid, car washing sponge/wool gloves, detail brush, absorbent towel in advance, and choose a cool and ventilated area for operation.
If the vehicle has just been driven or exposed to the sun, it needs to be left to cool to room temperature to avoid damage to the paint due to thermal expansion and contraction during washing. Put away the rearview mirror, turn off the automatic wiper, and ensure that the charging cover/window is sealed to avoid water ingress.

2. Cleaning steps
Rinse the dust on the surface of the car body with clean water, focusing on cleaning the tires, wheels and chassis mud and sand. Dilute the water wax car washing liquid in proportion and pour it into the PA pot. Use the car washing gun to make dense foam to cover the entire car, let it stand for 3-5 minutes, and use the lubricating effect of the foam to loosen stubborn stains such as mud, sand, and shellac. Then rinse the foam from bottom to top, use the water flow to take away the loose dirt, and reduce the risk of subsequent scrubbing and scratching. Use a car washing glove or sponge to clean the car in the order of "roof → window → hood → door → rear". After cleaning each sheet metal surface, clean the tool with a bucket of clean water to avoid residual sand and gravel scratching the paint surface. After cleaning, rinse the car body from top to bottom with clean water to ensure that there is no foam residue. Focus on checking the seams, wheel arches and other areas prone to water accumulation. Finally, use a microfiber towel or suede cloth to absorb water by zone to avoid residual water stains. Wipe the glass area separately to improve transparency.
