1、 Characteristics of stainless steel cups
Strong durability
Stainless steel (such as 304/316) is drop resistant, corrosion-resistant, and more wear-resistant than glass and ceramics.
Suitable for outdoor, travel, sports and other scenarios.
Insulation and cooling
Double layer vacuum stainless steel cups (such as insulated cups) can keep warm for 6-12 hours and cool for 12-24 hours.
Single layer cups are suitable for daily consumption and dissipate heat quickly.
Safety and hygiene
Food grade 304/316 stainless steel, free of harmful substances such as BPA.
Smooth surface, not prone to bacterial growth, easy to clean.
Environmentally friendly and reusable
Replace disposable plastic cups to reduce environmental pollution.
2、 Common types of stainless steel cups
| type | characteristic | Applicable scenarios |
| vacuum cup | Double layer vacuum, insulation and cooling | Office, Outdoor, Travel |
| Random cup | Single layer, lightweight and easy to carry | Drink water and exercise regularly |

3、 How to choose stainless steel cup utensils?
Look at the material
304 stainless steel: universal food grade, high cost-effectiveness.
316 stainless steel: more corrosion-resistant, suitable for storing acidic beverages (such as juice and coffee).
201/202 stainless steel: prone to rusting, not recommended for selection.
Look at the craftsmanship
Double layer vacuum: good insulation effect, but heavier.
Single layer: lightweight, suitable for daily use.
Cup mouth design: wide mouth easy to clean, narrow mouth leak proof.
Check authentication
Food grade certification: such as GB 4806.9 (China), FDA (USA).
Leak proof test: Check the sealing of the cup lid (inverted shaking test).
Check capacity
350-500ml: Suitable for carrying around.
500-750ml: Suitable for sports and outdoor activities.
1L or above: Suitable for long-term outdoor or office use.
4、 Use and maintenance of stainless steel cups
✅& nbsp; Correct usage method:
Before using the new cup for the first time, clean it with warm water and a small amount of neutral detergent.
Avoid carbonated drinks (which may cause high air pressure).
It is recommended to preheat hot drinks first (pour in hot water and let it sit for 1 minute before filling).
❌& nbsp; Avoid the following operations:
Long term storage of high salt, strong acid (such as lemon juice, vinegar) drinks.
Heat in the microwave (stainless steel cannot enter the microwave!).
Use a steel wire ball or strong acid cleaner to scrub.
�� Cleaning and maintenance techniques:
Daily cleaning: Warm water+soft cloth, soak stubborn stains in baking soda or white vinegar.
Deodorizing: Add lemon slices and warm water and let it stand for a few hours.
Rust prevention: Wipe dry promptly after use and avoid storing in damp conditions.
5、 Frequently Asked Questions and Answers
Q1: Does stainless steel cup coffee/tea leave a taste?
A: 316 stainless steel has stronger corrosion resistance and is less prone to residual odors; 304 is also available, but it is recommended to clean it promptly.
Q2: Why does the outer wall of my stainless steel cup sweat?
A: If there are condensation droplets on the outer wall of the double-layer vacuum cup, it indicates that the insulation is normal; The reason why single-layer cups sweat is due to the large temperature difference between the inside and outside.
Q3: Can stainless steel cups be used to make tea?
A: Sure, but it is recommended to use a tea filter to avoid discoloration of the cup wall caused by prolonged soaking of the tea leaves.
Q4: How to determine if it is genuine 304 stainless steel?
A: Use stainless steel testing solution (304 turns red, 201/202 turns black), or check the product testing report.
