The thermos cup is generally a water container made of ceramic or stainless steel with a vacuum layer, with a lid on the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of liquids such as water inside to achieve the purpose of heat preservation. When drinking coffee, tea or beverages frequently, the inner tank will change color. This is normal, and it can be removed with a bottle brush for hydro flask.

With the upgrading of environmental protection concept, many customers will choose plant-based brushes. Plant-based brushes can clean ceramic cups, but they cannot be used to clean stainless steel cups. Do you know why?

Plant wool is generally processed from stem and leaf fibers. Because it is plant fiber, it has good water absorption. However, the bottle brush for hydro flask of plant fiber has another characteristic, that is, it is very hard; Nylon, pig bristles and other materials, plant fibers are particularly hard to the touch, and have poor recovery. Therefore, if used to clean stainless steel bottles, the excessively hard wool will scratch the bottles and destroy their insulation effect.
