The first type: If the leather sofa is stained with soy sauce, you can use a knife to cut the fresh lotus root, and then apply the fresh lotus root juice to the soy sauce stain. After 10 minutes of washing in water, you can remove soy sauce stains.
The second method is to soak the leather sofa set, then apply some soda powder to the soy sauce stained area, and then wash it with water after 10 minutes, so that the soy sauce stain can be removed.
The third method is to soak the stained area with water, then sprinkle a spoonful of white sugar, and rub it by hand. You can see that part of the soy sauce stained on the sugar, and then washed with water to remove the stain.
These three methods are some very common small methods in life. Of course, if you can’t remove the grease on the leather sofa, you must find a professional master, otherwise it will cause damage to the leather sofa.
