The process of dry cleaning involves gently stirring clothes soaked in solvent until dirt and some oily stains are removed. In addition to general cleaning, so-called dry cleaning also includes using solvents to dissolve stains and remove stains. Inject lubricating oil into clothing to eliminate stains; convert stains into soluble or invisible substances through specific chemical reactions.

Oil stains can also be "dry cleaned" directly with toothpaste. After the clothes are stained with oil stains, squeeze some toothpaste and moisten it with a few drops of water. Apply evenly to the oil stains and rub gently. After the white foam covers the entire piece of cloth, use a small amount of water to remove the toothpaste and you can say goodbye to oil stains.

The specific steps for cleaning by yourself are as follows:

1. First prepare a large basin and put an appropriate amount of warm water.

2. Soak the oil-stained area in warm water for five minutes to keep the oil-stained area moist.

3. Apply toothpaste to the oil stain and let it sit for five minutes.

4. Dip a small amount of toothpaste into the toothbrush and scrub the oily areas.

5. Clean the oil-stained parts of the down jacket in clean water.

6. Check the down jacket after dealing with the oil stains. Just dry the down jacket in a ventilated place.
