How to wash off the blood in the pants:
1, fresh blood
How to wash clothes when blood is stained, if you find blood stains at this time, immediately wash with cold water or light salt water (hot water is not allowed, because the blood contains protein, it will solidify when heated, and it will not melt easily), and then use soap or 10% Potassium iodide solution for cleaning. If you find that the blood stain has not disappeared completely, you should put a cloth on the back of the blood stain, spread slices of white radish or pureed white radish on the blood stain, and then pat vigorously, or wash with enzyme laundry detergent, the effect is quite good, and finally use water Just wash it.
2, old blood stains
How to wash the blood stains on clothes if they have solidified and become stale blood stains? First, you should soak them in cold water for a long time. Because when the blood is not coagulated, the iron in heme is in the form of ferrous iron and can be dissolved in water. Over time, the ferrous iron in the heme is oxidized into trivalent iron, which is coagulated together with the protein, and it is difficult to wash off the blood stains formed on the fabric. Enzyme-added laundry detergent can be used to soak for a long time to remove the blood stains between the fibers. The alkaline protease in the enzyme-added laundry powder can relax and disintegrate the protein in the blood stains and peel them from the fabric. If it is still not clean, wipe the contaminated area with tartaric acid solution or ammonia (10%), or scrub with 10%-15% oxalic acid solution for 1 to 2 minutes, because oxalic acid is a reducing agent and can remove the trivalent insoluble in water. Iron is reduced to divalent iron, which is soluble in water.
What to do if you stick gum on your pants:
1. Vinegar method: soak the chewing gum on the clothes with vinegar, stop for a while, and gently scrape it off with a razor blade. For the masses, this method is the most convenient and feasible method.
2. Freezing method: This method requires a refrigerator at home. Put the clothes with chewing gum in the refrigerator for two hours. After freezing, the chewing gum loses its stickiness, and it will fall off as soon as it is gently removed. If you don’t have a refrigerator, you can also put ice cubes on the chewing gum area. After a while, the chewing gum can be easily removed. The principle of the two is the same.
3. Gasoline method: Chewing gum can be dissolved in gasoline. Put the part that holds the chewing gum into gasoline. After a period of time, the chewing gum will degrade, so just wash it.
