How do you save books that have come across food crumbs?

Books and periodicals are people's precious wealth, and if they are not kept well, they are not conducive to long-term use. So how should our families protect and collect books?

Humidity is very unfavorable to books, because the non-cellulose components in the paper or the acid, alkali, bleaching powder and other harmful substances remaining in the paper will cause the aging of the paper and the corrosive effect on the fiber of the paper under the influence of high temperature and high humidity.

In addition, dampness can also cause mold and insect damage to books. Therefore, the bookshelves and bookcases of the family should be placed in a dry and ventilated place. All kinds of light are harmful to books, and sunlight in particular is even more harmful. Therefore, the bookshelves should be protected from direct sunlight.

For books that have been damp and waterlogged, the method of ventilation and drying should be adopted, and they must not be exposed to sunlight to prevent the writing from turning yellow and brittle.

Books should be protected from insects. Bookshelves and bookcases can be placed with some paper-wrapped sanitary balls, natural camphor sperm blocks, camphor powder and other harmless insecticide drugs; In addition, books should be frequently overturned, and books and periodicals that are eaten by insects and rats should be dealt with in a timely manner to prevent the spread.

When the books are placed, hardcover books and paperback books can be placed in real place, with the spine facing outward, which is easy to find. When placed, if the layer is not full, you can put a book file to avoid the book being loose and crooked, causing the back of the book to be bent and the pages to be curled. Thread-bound books are lighter and should not be placed upright.

It is also better to lay flat the thread-bound book with a letter sleeve. Books with large openings (e.g. journals and magazines) should not be shoehorned into low shelves. Keep bookshelves and bookcases clean. Dust not only contaminates books, but also causes moths and mildew.

Damaged books should be repaired in time, especially the wrinkles in the corners of the books, and they should be leveled at any time. To remember to see a page of the book, use bookmarks, not fold corners.

Books and periodicals with finger marks, oil stains, etc., can be soaked in cotton soaked in soapy water and scrubbed once or twice, and then use absorbent paper to absorb the water.

If there is ink stains, you can use absorbent paper to pad under the pages of the ink, gently scrub them with a cotton ball soaked in hydrogen peroxide, and then cover it with a piece of absorbent paper, press a few thicker books on the paper, and when the pages are dry, the ink will disappear.

Books and periodicals can be scrubbed with a cotton ball soaked in alum water, and then the water can be blotted dry with absorbent paper.

Good luck! Reference.

Camphor wow works great haha.

You've used too much oil-controlling facial cleanser, and your face is dry and peeling, right? You use a mild facial cleanser that can be washed off, and then wipe something moisturizing and moisturizing, and you are severely dehydrated, and you prove that there is an imbalance between water and oil.

It is recommended that you use some oil control and hydration products. Having oil does not mean that there is no water. There are many times when oil production is a manifestation of water production.

1. Put all food in the refrigerator or use preservatives.

Putting desiccant next to the book and some shells, like abalone shells, can also be used to protect it, and a small amount of mothballs, if necessary, you can wrap the book cover and put it in the cabinet.

Books are also considered organic, and too much dryness can damage the paper.

If it does not move, the gas phase method is the best way, sealing and filling with inert gas.

Use a glass bottle of the right size (cans, bottles, coffee bottles, etc.), seal the bottle mouth with plastic wrap before capping, and then close the cap after sealing, so that it is equivalent to a vacuum state that can be maintained for a long time.

You eat it right away, within a week. Do not verbally tie it tightly and put it in the refrigerator. Don't leak anymore.

Vacuum seal with a plastic bag and place it in a dry place.

If possible, put some desiccant or something.

1. Bananas: If you put them in the refrigerator, they will turn black and taste bad.

2. Bread: The loss of moisture will affect the taste, and it is best not to store it in the refrigerator when it is not easy to become moldy, and it must be stored in the freezer when it is placed in the refrigerator.

3. Eggs: If you put eggs in the refrigerator, they will absorb the flavor in the refrigerator, and the eggs will be damaged.

4. Mayonnaise: Mayonnaise is easy to decompose below 9 degrees, and fungi are easy to multiply, so it is best to store it at room temperature.

5. Potatoes and radish: If potatoes are stored in the refrigerator, they will greatly affect the taste, so they should be stored in a room without sunlight. If the radish is kept in the refrigerator for a long time, the color and taste will be affected.

6. Carrots and tofu: If the carrots are placed in the refrigerator, the moisture in them will freeze, affecting the texture and losing nutrients. Tofu is best to eat immediately after purchase.

7. Canned food: When canned food is made, it is made for long-term preservation, so it makes no sense to put it in the refrigerator. After opening the can, the remaining contents are stored in other containers.

8. Tomatoes: After tomatoes are frozen at low temperature, the flesh is blister-like, soft and rotten, or there is a phenomenon of spallation, there are black spots on the surface, undercooked, no umami, and in serious cases, it is rancid and rotten.

9. Ham: If the ham is stored in the refrigerator at low temperature, the moisture in it will freeze, the fat will precipitate, the leg meat will clump or loose, the meat will become tasteful, and it is easy to spoil.

10. Chocolate: After the chocolate is frozen in the refrigerator, once it is taken out, a layer of hoarfrost will form on its surface at room temperature, which is very easy to mold and deteriorate and lose its original taste.

11. Cucumbers and green peppers: cucumbers and green peppers are stored in the refrigerator for a long time, and frostbite "injury" will appear - blackening, softness, and flavor. Cucumbers also grow and are sticky.

Because the storage temperature in the refrigerator is generally about 4 to 6, while the cucumber storage temperature is 10 -12, and the green pepper is 7 to 8. Therefore, it is not suitable to exist for a long time.

12. Fresh lychee: If the fresh lychee is placed in the environment of 0 for a day, the skin will turn black and the flesh will become flavorful.

Most tropical fruits such as dragon fruit, mango, lychee, longan, papaya, and rambutan are afraid of cold and should not be refrigerated in the refrigerator. Frostbitten fruits are not only destroyed in nutrients, but also spoil easily. After a few more days, the flesh will rot.

How long does food last in the fridge list:

Fresh eggs: refrigerate for 30-60 days.

Cooked eggs: refrigerate for 6-7 days.

Milk: Refrigerate for 5-6 days.

Yogurt: refrigerate for 7-10 days.

Fish: refrigerated for 1-2 days frozen for 90-180 days.

Beef: Refrigerated for 1-2 days Frozen for 90 days.

Steak: refrigerated for 2-3 days, frozen for 270 days.

Sausages: refrigerated for 9 days, frozen for 60 days.

Chicken: refrigerated for 2-3 days, frozen for 360 days.

Canned food: Refrigerated unopened for 360 days.

Peanut butter, tahini: open and refrigerated for 90 days.

Coffee: Refrigerated after opening the can for 14 days.

Apples: Refrigerate for 7-12 days.

Citrus: Refrigerate for 7 days.

Pears: Refrigerate for 1-2 days.

Ripe tomatoes: refrigerate for 12 days.

Spinach: refrigerate for 3-5 days.

Carrots and celery: refrigerate for 7-14 days.

The following foods should not be stored in the refrigerator:

1) Bananas: Stored in an environment below 12 will make them black and rotten.

3) Cucumber: If you leave it in the refrigerator for three days, the skin will become water-soaked and lose the flavor it holds.

4) Tomatoes: After freezing, some or all of the fruits will be soaked in water and soft and rot, showing brown round spots.

It is better not to put bread in the refrigerator: the starch straight chain part of the flour has aged during the baking process, which is why the bread develops an elastic and soft structure. As the bread is left for a longer period of time, the amylopectin in the bread slowly associates, and the soft bread gradually hardens, a phenomenon called "aging".

The rate at which "aging" is temperature dependent. It ages faster at low temperatures (above the freezing point), while bread hardens faster when it is stored in the refrigerator.

Cucumbers and green peppers should not be stored in the refrigerator for a long time: If green peppers are stored in the refrigerator for a long time, they will have frostbite "injury" - blackening, softness, and taste. Cucumbers also grow sticky hair.

Because the temperature stored in the refrigerator is generally about 4 to 6, while the suitable storage temperature for cucumbers is 10 to 12, and green peppers are 7 to 8. Therefore, it is not suitable to exist for a long time.

Another place to be clear is that the principle of storing food in the refrigerator is to slow down the growth and reproduction of microorganisms, and cannot kill microorganisms. The most suitable reproduction temperature for most microorganisms is around 37 degrees Celsius, and some can multiply rapidly above 20 degrees Celsius, although the vast majority of microorganisms grow slowly below 10 degrees Celsius, but there are still some bacteria that can survive or even multiply at lower temperatures.

Therefore, inappropriate storage temperature, high food temperature, raw and cooked cross-storage, etc., all affect the refrigeration effect and reduce the "insurance coefficient" of the refrigerator.

Let me tell you some common sense, good answer**I wish your whole family happiness and health! Please be sure to prevent the occurrence of "refrigerator diarrhea" and be sure to store processed foods reasonably.

1.Keep a thermometer in the refrigerator room and keep it at 4-10.

2.When storing, raw and cooked should be separated, and packed separately in a plastic wrap box or plastic wrap to avoid cross-contamination.

3.Cooked food should be stored when it has been cooled to room temperature, as it is dangerous to store at room temperature for longer periods of time.

4.The food taken out of the refrigerator should be heated indoors after it has been warmed before heating, and the heating time should be more than 15 minutes.

5.The storage time should not be too long, and the food that needs to be stored for a longer time should be stored in the freezer.

6.Clean the refrigerator frequently and keep it clean.

1.**is to express it with**.

2.Comics are all expressed in **.

Oh, hehe, seriously! ）

Get off the sail and pat Hui to carry a reading treasure and go to the top to find it.

I, He Liang, found it.

It could also be sediment in tap water, or attached toothpaste, which is usually changed every three months, so you don't need to worry too much...

Toothpaste that has not been rinsed clean.

It is still necessary to change the toothbrush once a month, and it is a waste to change it more often.

I suspect it's the shedding of the toothbrush bristles.
