1. Use No. 120 solvent gasoline, or chemical organic solvents such as trichlorethylene, tetrachlorethylene, benzene, etc., dip it in with a small brown brush or a small towel, and lightly brush or scrub the stain repeatedly. The grease and gasoline in the stain will dissolve, and as the chemicals evaporate, the stain will gradually disappear. It should be noted that traces often appear after oil stains are removed. The reason is that after the oil dissolves, it does not completely evaporate and remains on the fabric.
The removal method is: put 120 grams of solvent gasoline in a watering can, spray it evenly around the traces, and the area should be larger. While spraying, dry wipe with a clean small towel, and the traces can be removed.
2. Oil stains that have been contaminated for a short time can be removed by washing with crushed soap washed with boiling water. 3. Wash with the original liquid detergent, and then rinse with clean water.
