Question 1: How to clean stainless steel products? 1. First prepare the stainless steel tableware that needs to be cleaned.

2. Then pour the tomato juice and dish soap into the stainless steel tableware that needs to be cleaned, and soak for 3 to 5 minutes.

3. After soaking, you will find that it is very convenient to clean.

Note:

You don’t need too much dish soap and tomato juice, just a 1:1 ratio!

Question 2: How to clean the stainless steel surface? Commonly used stainless steel surface treatment technologies include the following treatment methods: ① surface whitening treatment; ② surface mirror brightening treatment; ③ surface coloring treatment. 1.3.1 Surface whitening treatment: During the processing of stainless steel, black oxide scale is produced after rolling, edging, welding or artificial surface roasting and heating. This hard gray-black oxide scale is mainly composed of two EO4 components, NiCr2O4 and NiF. In the past, hydrofluoric acid and nitric acid were generally used to remove it by strong corrosion methods. However, this method costs a lot, pollutes the environment, is harmful to the human body, and is highly corrosive, so it is gradually being eliminated. At present, there are two main methods for treating oxide scale: (1) Sandblasting (shot) method: It mainly uses the method of spraying micro glass beads to remove the black oxide scale on the surface. ⑵ Chemical method: Use a pollution-free pickling passivation paste and a normal temperature non-toxic cleaning solution with inorganic additives for immersion. In order to achieve the purpose of whitening the original color of stainless steel. After treatment, it basically looks like a dull color. This method is more suitable for large and complex products. 1.3.2 Stainless steel surface mirror brightening treatment method: Depending on the complexity of the stainless steel product and user requirements, mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve mirror gloss. The advantages and disadvantages of these three methods are as follows: 1.3.3 Surface coloring treatment: Stainless steel coloring not only gives various colors to stainless steel products, increases the variety of designs and colors of the products, but also improves the wear resistance and corrosion resistance of the products. There are several stainless steel coloring methods: ⑴ chemical oxidation coloring method; ⑵ electrochemical oxidation coloring method; ⑶ ion deposition oxide coloring method; ⑷ high temperature oxidation coloring method; ⑸ gas phase cracking coloring method. A brief overview of various methods is as follows: ⑴Chemical oxidation coloring method: The color of the film is formed through chemical oxidation in a specific solution. There are dichromate method, mixed sodium salt method, sulfide method, acidic oxidation method and alkaline oxidation method. . Generally, the INCO method is commonly used, but if you want to ensure that the color of a batch of products is consistent, you must use a reference electrode to control it. ⑵Electrochemical coloring method: The color of the film is formed through electrochemical oxidation in a specific solution. ⑶ Ion deposition oxide coloring method chemical method: the stainless steel workpiece is placed in a vacuum coating machine for vacuum evaporation plating. For example: titanium-plated watch cases and watch straps are generally golden yellow. This method is suitable for high-volume product processing. Because of the large investment and high cost, small batch products are not cost-effective. ⑷High-temperature oxidation coloring method: The workpiece is immersed in a specific molten salt and maintained at certain process parameters, so that the workpiece forms an oxide film of a certain thickness and presents various colors. ⑸ Vapor phase cracking coloring method: more complex and less used in industry. 1.3 The choice of treatment method for stainless steel surface treatment depends on the product structure, material, and different requirements for the surface, and the appropriate method should be selected for treatment.

Question 3: How to clean the protective film of stainless steel products? There is something written on the protective film. It is usually torn off within 3 months after leaving the factory. If it is not torn off in time. Just scrub with alcohol. It's easy to clean off if it doesn't take long. If it takes a long time. Then clean it several times.

Question 4: How to clean new stainless steel products? Just use ordinary dishwashing liquid and dishcloth. If you have a disinfection cabinet at home, it would be better if you can heat it in the disinfection cabinet. Mainly the stainless steel surface. There may be a little bit of residual steel powder and dust from packaging materials remaining. After cleaning, it is naturally best to let it go to high temperature. If not, just rinse it a few more times.

Question 5: How to clean stainless steel products? Method: Clean with mild detergent

1. Treat the stain as soon as possible.

If necessary and possible, soak the object in dilute cleaning solution. If you're cleaning something small like a stainless steel pot, you can soak it in washing-up liquid to help remove burnt food or other stains. For very difficult stains, soak it overnight. For larger objects or dishes that are not very dirty, skip this step.

2. Wipe the stainless steel with a damp cloth or thick sponge. Take a cloth or sponge and gently wipe the surface. Usually no force is required. Wash and wring out the rag from time to time to keep it moist and clean to avoid hard dirt causing abrasion on the steel surface. If the stainless steel surface is polished, do not rub the surface hard when wiping, but rub along the surface and avoid making circular wiping on the surface.

3. Rinse the stainless steel thoroughly with warm, clean water. Dampen and wipe the stainless steel with a clean rag or sponge. Be sure to wash away all detergent residue, otherwise streaks and discoloration will form on the surface.

4. Repeat as many times as necessary. General cleaning will remove most stains and contaminants, but if stains remain, repeat the process.

Be patient—consistent wiping can usually remove even the most stubborn stains.

Question 6: How to deal with stubborn water stains on stainless steel products? Use stainless steel cleaning fluid. It can also be cleaned with stainless steel pickling liquid. But the time has to be quick. Good rust removal ability.

Question 7: How to clean the non-stick traces on stainless steel products? To remove self-adhesive labels from stainless steel products, you can bake them with fire and peel them off carefully, or you can use cooking oil to remove them by smearing them and soaking them.

Question 8: There is grease on stainless steel products. How to remove it quickly? Stainless steel appliances: After being used for a long time, scratches will appear on them, which affects the appearance. This is caused by frequent cleaning with steel wool. How to clean stainless steel products so that they are clean and scratch-free? 1． Cut the carrots into 2-3cm heads. 2. Pierce the carrot tops with chopsticks and roast them over the fire. 3． When the carrot tops are roasted soft and the surface changes color a little, you can use the roasted soft carrot tops to test the stainless steel tableware. You see, the oil stains on the stainless steel plates can be easily wiped off, and they will be clean after rinsing them with clean water.

Stainless steel kettle: The appearance will gradually turn black after being used for a long time. At this time, the dust and oil on the surface are burned into charcoal, which not only covers the surface of the pot, but also becomes hard and cannot be easily removed with sandpaper. Moreover, the sandpaper will damage the surface gloss. How to remove stains on the surface of stainless steel kettle? You can first add half a bowl of boiling water with caustic soda, soak a towel and spread it on the pot surface for half an hour, then use a scouring pad dipped in detergent to wipe it off evenly. If it is still not removed, you can use a kitchen knife to gently scrape the veneer, and then clean it again with the above method. It can also be wiped off with commercially available stain removers.

Remove the rust in the stainless steel pot: After using the stainless steel pot for a period of time, there will be light brown rust in the pot, which cannot be wiped off by hand. If you boil a pot of water and then move the pot, you will find small objects floating in the water. But when the water is taken out, those small floating objects disappear. What happens now? In fact, since it is called a stainless steel pot, it will not rust. Those light brown things are not rust, but substances formed on the pot wall by the minerals in the water that condense over time. These traces do not need to be removed and are not harmful to the human body. If it must be cleaned, try pouring a little white vinegar into the pot and shaking it well, then boil it slowly for a while to see the effect. However, if you have boiled white vinegar, you must wash it off with a cleaning agent such as dish soap, otherwise it will easily leave a sour smell. You can also use fine water sandpaper to remove those marks evenly. As for the small floating objects mentioned above, they are still related to the water quality. These floating objects are more obvious in well water or mountain spring water. They are crystals formed by minerals.

Remove the rainbow color that appears on the bottom of the stainless steel pot after cooking soup: it is called stainless steel and must be able to withstand acid and alkali corrosion, so making soup does not affect the quality of the steel, but the rainbow color on the bottom of the pot may be After being heated over a fierce fire, the surface gloss will only change. It will not harm health and does not need to be removed. If it needs to be wiped off, dry sanding can be done with No. 0 water sandpaper.

Cleaning stainless steel countertops: Vegetable and fruit residues, which have always been regarded as garbage, can also be used to remove oil stains and polish stainless steel appliances. So don't use it until you throw it away. Vegetable and fruit cores, potato peels, radish tops and other vegetable pomace that are usually treated as garbage can be used to wipe the stainless steel countertops, which can make the originally slimy and tarnished countertops look brand new again. As long as you develop the habit of wiping the stainless steel countertops with these waste materials before discarding them, you can keep the countertops clean. After wiping, please wipe it with clean water once.

① When heating plastic bottles containing baby milk, the dry water is dissolved on the bottom of the stainless steel pot and is difficult to remove. You can try the following method: add a little water and simmer over low heat. When the water-dried colloid is soft, slowly pick it out and shovel it clean. You can still use this pot to boil baby bottles later without causing any harm.

② After the stainless steel kettle has been used for a long time, scale and oil stains will make the surface of the kettle dark. You can try to wipe it with a scouring pad woven with acrylic wool, which can restore the luster without damaging the surface.

③ Stainless steel utensils smell of oil. If you don’t know whether it is edible oil, industrial oil or paint, you can buy yeast tablets from the pharmacy, mash them and sprinkle them on the oil stains, then sprinkle a little water and let them dissolve. Finally, add a little washing powder to wipe it.

④ If the boiled water produced by a stainless steel kettle has an "iron smell", it may be caused by impurities on the surface of the pot that have not been cleaned, because it is said that boiling water in a stainless steel kettle should not have an "iron smell" "of. In this regard, you can first use a new scouring pad dipped in scouring powder and a few drops of detergent to clean it carefully, and then boil it with a cup of white vinegar and two cups of water (this method is to remove minerals from the water). Can remove the "iron smell".

Question 9: What is the best way to clean stainless steel? Stainless steel is made of iron-chromium alloy mixed with some other trace elements. Because of its good metal properties and resistance to rust compared to other metals, the utensils made are beautiful and durable. Therefore, more and more are used to make kitchen utensils and gradually enter the majority of households. However, if the user lacks relevant knowledge and uses it improperly, the trace metal elements in stainless steel will also slowly accumulate in the human body. When it reaches a certain limit, it will harm human health. Therefore, you must pay attention to the following points when using stainless steel kitchenware and tableware:

1. Do not store salt, soy sauce, vegetable soup, etc. for a long time, because these foods contain many electrolytes. If they are stored for a long time, the stainless steel Like other metals, it will react electrochemically with these electrolytes, causing toxic metal elements to be dissolved.

2. Stainless steel vessels cannot be used to cook Chinese medicine, because Chinese medicine contains many alkaloids, organic acids and other ingredients, especially under heating conditions, it is difficult to avoid chemical reactions with them, which will render the medicine ineffective. , and even produce some more toxic compounds.

3. Do not use strongly alkaline or strongly oxidizing chemicals such as soda, bleach, sodium hypochlorite, etc. for washing. Because these substances are electrolytes, they will also react chemically with stainless steel.

In order to maintain the gorgeous surface of stainless steel products and extend their service life, regular maintenance is required.

1. Wash surface dust and dirt with soap, weak detergent and warm water

2. Use warm water and weak detergent to wash the trademark and film. Use alcohol or organic solvents to clean the adhesive components.

3. If the surface is contaminated by grease, oil, or lubricating oil, wipe it clean with a soft cloth, and then wash it with neutral detergent or ammonia solution or special detergent.

4. If there is acid attached, rinse with water immediately, then soak with ammonia solution or neutral carbonated soda solution, and then wash with neutral washing or warm water.

5. The rainbow pattern on the surface of stainless steel is caused by excessive use of detergent or oil. It can be washed away with warm water and neutral washing.

6. Rust caused by dirt on the surface of stainless steel can be washed with 10% nitric acid or abrasive detergent, or with special cleaning chemicals

Question 10: There is a lot of oil stains on stainless steel products. How to Clean When the surface is seriously oily, organic solvents such as gasoline should be used to clean it. When there is less oil pollution, chemical degreasing, electrochemical degreasing, etc. can be used.

(1) Chemical degreasing:

Sodium hydroxide 60~80g/L, sodium phosphate 20~40g/L, sodium carbonate 20~40g/L, sodium silicate 3 ~10g/L. The total alkalinity is 65~100g/L, the temperature is 70~90℃, and the time is until the oil is removed.

(2) Electrochemical oil removal: sodium hydroxide 30~50g/L, sodium phosphate 20~30g/L, sodium carbonate 20~30g/L, water glass 3~5g/L. Total alkalinity 40~60g/L, temperature 60~80°C, current density 3~10A/dm2, time: cathode 3~5min, anode 1~5min, electrode material is steel plate or nickel-plated steel plate.

Large-sized stainless steel products, such as composite panels, large pressure vessels, etc., cannot be placed in a degreasing tank for degreasing. You can use a rag or mop dipped in an aqueous solution of room temperature degreasing agent, washing powder, etc. to wipe and degrease. . For large batches, small size and light weight parts, it is better to use a roller to degrease. Put these parts into the drum and add appropriate abrasives and degreasers for degreasing. The effect is good, the cost is low, and the operation is easy. But it is not suitable for thin parts that are easily deformed. The standard for clean degreasing is: wash with water after degreasing, and the water film should not crack for 30 seconds. Refer to the information knowledge of jsxhhx/
