Can you wash your hands with dirty water, you can't wash your hands completely, dirty water handwashing just washes the surface, but bacteria are still there.

It can't be washed at all. I want to wash my hands with running water.

That depends"Wash well"What is the standard, there is an old saying:"Wash out the white melons in the muddy water"That's it.

The more you wash, the dirtier it gets, so change the water to clean it.

1. Clean water cannot wash off all the bacteria on your hands.

2. When washing hands, you need to use soap and hand sanitizer. Soap removes bacteria from your hands** and dissolves things that are difficult to wash off with water. Washing hands with soap can reduce the likelihood of dysentery than rinsing with water alone.

3. If you're not sure whether soap or hand sanitizer is available in public places, it's also a good idea to carry a portable hand sanitizer with you. It's a good idea to dry your hands with a paper towel after washing them, as wet hands are more likely to carry more germs when touching things than dry hands.

Hello classmate, this doesn't matter, you don't eat with your hands, although clean water can't completely remove bacteria, but you can also wash your hands, don't worry about this. The most important thing is that when eating, the hands are not directly touching the food, even if they do, it doesn't matter.

Hope it helps.

For example, dirt stains and the like, in some places involving ghosts or psychics, dirty things may refer to ghosts, ghosts, etc., and in biology or chemistry, they can also refer to contaminated samples and reagents.

Why does water wash away dirt? Maybe it simply takes away the dirt, like the river takes away the wood chips that are thrown down?

Then give it a try. Put your dirty hands under the tap and flush. Will it get clean?

I'm afraid not. You know no one is going to wash their hands like that. When we wash our hands, we always rub one hand against the other. Why? To wipe off the dirt and scrape it off.

That's exactly what it takes to do laundry. We don't just put the laundry in the water and forget it, but scrub it – by hand or even with a brush.

Scrubbing clothes, this is rubbing dirt off clothes, just like we use an eraser to wipe the handwriting from paper. Once the dirt is removed, it is not difficult for the water to wash it away.

1. The action of force, when water washes dirty things, it produces a force that separates the object from the dirty thing.

2. Water can dissolve dirty things in water, which is equivalent to washing off dirty things'Stuff.

Because, ordinary dirt is dissolved in water. So it can be washed off.

Some things are soluble in gasoline, such as cooking oil.

Water is a crystallization of hydrogen and oxygen. 4.5 billion years ago, there were about 4 clusters of water molecules. The diameter is about 0 2 nanometers.

The pH of water is about 10 5 and has negative bioelectricity of about 600 millivolts. With the indiscriminate discharge of plants and animals, etc. Attach anions (sulfuric acid, carbonic acid, nitric acid, phosphoric acid, chlorine, heavy metals, and other pollutants with negative bioelectricity) to hydrocolloids.

The cations (calcium, potassium, sodium, magnesium, selenium, etc.) that are inherently positive bioelectric in water lose their charge balance. Anions and cations should keep bioelectricity slightly conserved with each other, and the water molecules become larger. When the water is flowing, the hydrocolloids rub against each other and become electrified, separating the hydrocolloids into hydrogen and hydroxide ions.

Hydroxide ions are the cause of life and have a restorative function. Therefore, the anions on the contaminant are easily decomposed. So water has the effect of washing things.

Wash your hands with the right amount of hand sanitizer and rinse it thoroughly.

According to the oil or other stain components on the hands, as well as people's requirements, there are different varieties, one is ordinary hand sanitizer, one is disinfection products, and the other is a special type of heavy oil hand sanitizer. The former plays the role of cleaning and decontamination, and the latter contains antibacterial, bacteriostatic or bactericidal active ingredients. Hand sanitizers with heavy oil stains are mostly used to clean industrial oil stains (e.g. engine oil, gasoline, butter, diesel, etc.) and stubborn stains.

Different hand sanitizers are different in outer packaging, ordinary hand sanitizers are generally "quasi-brand", and hand sanitizers are mostly "elimination". Hand sanitizers generally do not contain phosphorus, aluminum, alkali, sodium alkylbenzene sulfonate and other ingredients, and adopt the principle of gentle decontamination, which is easy to accept.

Wash your hands properly.

Moisten your hands with water first, take an appropriate amount of hand sanitizer in the palm of your hand and rub your hands fully for at least 30 seconds, pay attention to rubbing to the fingertips and fingers during the process, and let the foam cover all parts of the whole hand, and rinse off with running water after rubbing. Finally, be careful to dry with a clean, dry towel or paper towel, preferably not tumble dry, because the rapid evaporation of surface water will cause **partial water loss, resulting in**dry hair and become rough.

If your hands are visibly dirty or bleeding, soap is better than hand sanitizer. In contact with people with diarrhoea, soap can also kill most pathogenic bacteria. When many people use hand sanitizer, they often press several drops at a time, which is not only a waste, but also makes their hands "dirtier" the more they wash.

Hand sanitizers are mostly formulated with alkaline ingredients, which also contain surfactants. If you squeeze too much at a time and can't be washed off in a short time, these substances are easy to stay on your hands, and hand sanitizer itself is highly concentrated, and one drop is enough to wash your hands clean.

In addition, it is recommended that the general household hand sanitizer is best to buy a small bottle, so as not to run out of bacteria and breed bacteria.

Although hand sanitizer is more popular nowadays, it is still much inferior to soap. In conclusion, hand sanitizer should not be used as a substitute for soap.

When your hands are dirty, you can't wash your hands with hand sanitizer once, and you need to wash your hands again.

If it is not enough, it should be rinsed repeatedly with running water to be clean.

In fact, soap or hand sanitizer are the same thing. What is the standard of washing, that is, whether there are bacteria, viruses and other substances that may affect the health of the body on the hands. This depends on what kind of hand sanitizer or soap you choose.

Personally, I feel that Shufujia soap is good, and the hand sanitizer for Anjie sterilization is also good, so there is no problem of washing feeling or not washing.

Not necessarily, at least two or three times.

A small toothbrush is used to assist in brushing for the cleanest.

Put soap on both hands, rub each finger on the front and back, and wash for more than 30 seconds.

This is a requirement for surgeons, but it is also applicable to ordinary people and scientific researchers who are often exposed to toxic drugs.

The seven-step handwashing method is as follows:

Step 3: Palms facing each other, cross your hands and rub them against each other along the finger seams;

Step 4: Hold the thumb of one hand and rotate and rub with the other hand, and the exchange is carried out;

Step 5: Bend the joints of each finger, rotate and rub in the palm of the other hand, and exchange;
