The screws on the lid of my pot are rusty.

It doesn't matter, people are already consuming iron, and there is a lot of iron in the blood. If all the iron in a person's body is extracted, an iron nail can be made.

Rust is 3-valent iron, which enters the stomach to form iron chloride, and the iron nail rusts melts into the water only in trace amounts, except for the absorbed ones, and the rest will be excreted from the body.

In the past, Chinese have always used iron pots to stir-fry and cook, and foreigners use aluminum pots. Therefore, Chinese people have anemia and Alzheimer's disease far lower than those in Europe and the United States.

So don't worry at all.

In addition, there may be bacteria in the rust, and it will get tetanus when it touches the wound, so it is better to replace the rusty screws quickly.

The screws are rusty, you can try the following:

1.The use of knocking, shocking, burning, and welding methods can temporarily solve the problem of rusting screws, you can pour some oil at the screw position, use the method of knocking and vibration, loosen around the screw, and then use a dry brush to evenly apply the oil to the screw. Rusty screws can be welded with a welding torch first, and then screwed off with a wrench.

2.Drip vinegar on the rusty screws, brush off the rust after four or five hours, and then wash it with clean water.

3.Mix baking soda and water, apply it to the screws, wait for a while, rotate the screws with a wrench, and wipe them clean with a cotton cloth.

4.You can use a rust remover to remove rust from the screws, spray the rust remover on the screws before use, wait a few minutes and then use a paper towel or rag to dip a small amount of gasoline and wipe the rusty screws until the rust is removed.

The above is the way to solve rusty screws, I hope it will help you.

First find a small saw blade to see slowly for a while, and then use a screwdriver and clamp to fix the screws in both directions, and the small screws that have been injured by the saw blade will be broken.

Drop a few drops of oil on top and try again in two days.

If the silk rusts are dead, you can take it out with cola, hammer, and cooking oil, taking cola as an example, the specific operation method is as follows:

1. Wrap the cotton cloth around the rusty screws that need to be unscrewed.

2. Then pour an appropriate amount of cola into the cotton cloth wrapped in the rusty screws, and soak the cotton cloth with the poured cola, and the ingredients in the cola will have a chemical reaction with the rust.

3. After standing for a few days, slowly take out the screws with wire cutters.

Hammer: Use a hammer to gently tap around the rusty screw, and after a while, the rusted screw will loosen, and then it can be easily unscrewed.

Cooking oil: Add a small amount of cooking oil to the perimeter of the screw, let it stand for about 5-10 minutes, and then gently rotate it with a vise to remove it.

Summary: If the silk is rusted, you can take it out with cola, hammer, and cooking oil.

Hello dear, for your inquiry, the screws on the lid are rusty and toxic. Rusty screws release toxic substances such as lead, cadmium and chromium, which are potentially harmful to human health. Therefore, it is advisable to use non-rusted pot lid screws, or replace rusty screws in time.

At the same time, when using the lid, care should also be taken not to allow the screws to come into direct contact with the food, so as to avoid the food being contaminated with the mold. The above questions have been answered for you, if you have other questions, please continue to ask, if there is no stool branch, please give a thumbs up! Good luck to you:

Have a good life and all the best!

A shock. For rusty screws, do not hard screw them with a wrench to prevent them from slipping the six-sided edges and corners of the screws, breaking the screws or breaking the wrench. At this time, you can use a hammer to gently shake the handle of the wrench, and the screws that are generally rusted can be vibrated and unscrewed.

Two knocks. With the edge of the square-topped hammer, it is easy to loosen the nut by striking the rusted nut. For example, the nuts that fix the bolts at both ends of the pedals of a bicycle can be struck with force according to the thickness of the pedal and the metal structure.

The nut at the cast iron can be used with a slightly larger force, and the plastic part should be gently beaten. If that doesn't work, you can easily remove the nut by tapping it in a circular motion with a hammer.

Three burns. Some screws are very seriously etched, and the above methods still do not work, so "fire attack" can be used. Use a gas welding oxidation flame to grill the screws and nuts thoroughly, and then drip a trace of oil on the red-hot screws.

The purpose of heating the screw is to make the screw expand when heated. The purpose of dripping oil is to make the screw shrink quickly when cold, increase the gap between the screw and the nut, and the nut can be unscrewed after the oil flows in. However, if there are plastic devices nearby, use this method with caution.

Four-stroke. The top of the screw of some devices is corroded and out of shape, and cannot be discharged with a wrench or wire cutter, which can be used by impact method. First, use a hammer and a top-permeated flat cone to impact a V-shaped groove in the vertical direction of the top of the screw, and then adjust the angle of the punch cone to impact in the direction of the screw.

Once loosened, the screws can be screwed out with a wire cutter. When the "one" or "ten" screw sliding, this method can also be used to screw out the screw in combination with the wire cutter.

Five welding. When disassembling a device, it is not uncommon to unscrew the screws. For the screws with broken tops, electric drills are generally not used, because the slightest carelessness will drill the wire holes.

It is better to weld a long piece of iron to the broken wire with electric welding. The cross-section of the iron block is determined by the diameter of the screw. After the iron is firmly welded, oil is quickly dripped into the solder joint to soak the nut.

After cooling, use a small iron cone to knock the other end of the iron back and forth in the horizontal direction, and when the screw is loose, rotate the iron to unscrew out the broken wire.

Hello, now there is this rust remover that can be soaked and then smeared.

Wet with some oil first, and then open it after it is fully wetted.
