Now there are many insulated water bottles in the market. They don't need special cleaning when they are bought. They have been disinfected before they leave the factory. You just need to scald the first bottle of water. Generally, the manual will also indicate how to maintain it.
1. Outer layer: the paint surface of the insulated water bottle is divided into various types: matte paint, bright finish paint, rubber paint, etc. The insulated water bottle of bright finish paint is not stained with ash or stain, and easy to clean. It can be maintained by using clean water or adding detergent.
2. Liner: the liner of the insulated water bottle is generally made of food grade 304 or 306 stainless steel. When it is used for the first time, it only needs to be soaked in boiling water for 2-3 times.
If you still don't feel relieved, you can use detergent to clean it, but you must use a soft sponge brush to clean it, otherwise it will damage the paint surface of the insulated water bottle body and leave traces, which is a pity. Use sponge brush, otherwise the paint surface will be easy to leave marks.
I usually use boiling water to scald my insulated water bottle. I don't drink the first cup of water. If I still feel peculiar smell, I will disperse the smell for a few days. If there is still an obvious smell, it means that the quality of the insulated water bottle may not be up to standard. The purchase of insulated water bottle depends on the material, not just the price.
