Peter from Russia emailed us and said that they needed to buy non-rusty, non-coated test tube brushes nylon. He said that the previously purchased test tube brushes nylon steel wire had a layer of glue on it, but after cleaning for a period of time, the glue fell off, exposing the steel wire inside, and it was easy to rust. He hoped to use a different steel wire material.

We recommended Peter our stainless-steel wire. For test tube brushes nylon, we generally choose stainless steel wire. If rubber-coated wire is used, the rubber layer is easily corroded, so that the internal iron wire is rusted. However, stainless steel wires are relatively stable and are not so easily corroded and rusted. But the cost of stainless steel will also be higher than the cost of the covered wire.

After a period of communication, we reached a cooperation and Peter received the test tube brushes nylon. A few months later, Peter emailed us again and wanted to purchase again. He said that the test tube brushes nylon he purchased from us last time is very durable. The stainless-steel wire is indeed better than the rubber-coated wire. It also makes sense.
