Stainless steel is characterized by a very thin but extremely durable and compact layer of a stable, rich chromium oxide film (protective film) on its surface, which prevents further oxygen penetration and oxidation, thereby achieving corrosion resistance.

Force. Once there is some reason, this film is constantly destroyed, and oxygen atoms in air or liquid will continuously penetrate, or iron atoms in metal will continuously separate, forming a loose oxygen

The iron is corroded, and the metal surface is constantly rusting. There are many forms of damage to this surface film,

The following are some common examples in daily life:

1. The surface of stainless steel is covered with dust or foreign metal particles containing other metal elements. In humid air, condensation water between the adhering matter and stainless steel will connect the two.

A micro battery, triggering an electrochemical reaction, damages the protective film, which is called electrochemical corrosion.

2. Stainless steel surfaces adhering to organic juices (such as fruit and vegetables, soup, phlegm, etc.) can form organic acids under the presence of water and oxygen. If left for a long time, these organic acids can corrode the metal surface.

3. Stainless steel surfaces may become adhered with acid, alkali, or salt-containing substances (such as alkaline water from decorating walls or lime water spray) which can cause local corrosion.

4. In polluted air (such as air containing large amounts of sulfur dioxide, carbon monoxide, and nitrogen oxides), when cooled and condensed, it forms acidic liquids such as sulfuric acid, nitric acid, and acetic acid, causing chemical corrosion.

All conditions can cause the destruction of the protective film on stainless steel, leading to rust. Therefore, to ensure that the metal surface remains permanently bright and is not corroded,

We suggest:

1. It is necessary to regularly clean and wipe the surface of decorative stainless steel to remove adherent substances and eliminate external factors that cause damage.

2. Coastal areas should use 316 stainless steel, which can resist seawater corrosion.

3. Some stainless steel pipes on the market do not meet the corresponding national standards for chemical composition, failing to meet the requirements for 304 material. This can also cause rust, which requires users to carefully choose a reputable manufacturer.

The product of the family.

【注意事项】：
1. Before using stainless steel tableware for food, it must be boiled and washed several times to perform high-temperature sterilization.
2. Avoid spills, falls, collisions, and strong impacts, as these may cause deformation of stainless steel products, affecting their appearance and effectiveness.
3. Stainless steel products should not be in contact with soy sauce, vinegar, and other salty substances (or other acidic or alkaline substances) for a long time, to prevent rusting.
4. Sometimes, the inside of stainless steel utensils may develop some red rust spots due to the presence of iron or other substances in the contents. You can remove these spots by soaking the utensils in warm water mixed with diluted vinegar for 30 minutes, and then thoroughly cleaning them.
5. Stainless steel utensils should be cleaned with soft cloths and dishwashing detergent diluted with warm water. Do not use alkaline bleach, metal scouring pads, or chemical rags.
6. To prevent the production of odors or stains and to maintain long-lasting cleanliness, after using stainless steel utensils, please clean them thoroughly and allow them to dry completely.
7. After stainless steel utensils are heated at high temperatures, do not directly touch them with your hands to avoid scalding.

Maintenance of Stainless Steel Kitchenware
Stainless steel kitchenware is both beautiful and practical, and it is deeply loved by everyone. However, when used in places like the kitchen, it is easy to become stained with oil and grease, making cleaning quite troublesome. Now we introduce two methods for removing stains:
1. Apply the cleaning powder on the surface of kitchen utensils and scrub it clean.
2. If detergent cannot completely clean the stain, use fine sand to gently rub the dirty area to remove the stain.
In addition, we can also pay more attention when using to avoid the accumulation of stains, such as adding oil when the pot is cold, cleaning after use, and drying the water stains, etc. Using orange peel together with cleaning powder to clean the surface can make old kitchen utensils shine like new.
