Anonymous users2024-01-24You can use 10 ammonia or 3 hydrogen peroxide to wipe the stain, and after a while, wash it with cold water.
If it is still not clean, wash it with 10-15 oxalic acid solution, and finally rinse it with water.
Whether it is a new trace or an old trace, it can be rubbed and cleaned with sulfur soap.
Apply hand oil to the blood stains, leave it on for about 15 minutes, and wash it with water and soap.

Anonymous users2024-01-23Hello answer, according to my query. Blood stains should be cleaned with cold water, which can be removed with hydrogen peroxide, and when the hydrogen peroxide is foamed, it should be dipped in a clean, white dry cloth. After a long time of blood stains, the ferrous iron in the heme is oxidized to trivalent iron, and coagulates together with the protein, which is difficult to wash off when it is stained on the fabric to form blood spots.
Freshly stained blood stains should be washed immediately with cold water (never hot water, as the blood clotted when heated). Hydrogen peroxide has a bleaching effect and has a noticeable effect when cleaning up blood stains. Hope it can help you.
Ask what to do with blood stains that have been in the business for a long time.
Apply the solution to the blood stain and gently scrape off the clotted blood stain with a spoon.
When the blood stains are completely dissolved, use a towel to absorb the excess water, and the mattress will be back to new condition!

Old blood stains can be washed away with oxalic acid. It can also be washed with lemon juice and salt water. (Even the ones are old.) (Except for the iron in hemoglobin).
Sulfur soap cannot be washed with hot water, only with cold water.
Use enzyme laundry detergent.
Collar clean, dish soap, hydrogen peroxide.

It should be washed off with gasoline.
Erase it with an eraser. Wetting is acceptable. Don't let the leather permeate the water, then the color will become darker. >>>More
Apply that Shanghai brand sulfur soap and brush with a brush. You try it, and the sulfur soap washes the blood very strongly. By the way, don't use hot water, just cool and cool.
When it is first contaminated, it should be washed immediately with cold water or light salt water (hot water is prohibited, because the blood contains protein, it will coagulate when heated, and it is not easy to dissolve), and then wash with soap or 10 potassium iodide solution; >>>More
After the wax part is removed, the wax that penetrates into it should be sucked with absorbent paper, and the white absorbent paper is placed on the sofa surface with wax, and heated on the paper with an iron or a stainless steel container filled with hot water, so that the wax can penetrate into the absorbent paper after melting, and the absorbent paper is replaced repeatedly until there is basically no wax. If the sofa cover can be removed, it is better to spread absorbent paper on the top and bottom. There is really no absorbent paper, handkerchief paper and toilet paper are all fine.
