Can I use someone else's used rag?

Better not. I used it. There must be some bacteria hidden in it.

Kitchen rags can use oil-free bamboo fiber rags. The characteristics of this rag are as follows: first, it has strong water absorption and strong oil removal ability. It is difficult to clean a common rag with detergent after it is stained with stains, while the bamboo fiber rag can be separated from the rag immediately by washing it with water and rubbing it gently. Clean towels are as bright as new. Second, it has strong antibacterial ability. Ordinary rags will turn yellow, slippery, greasy, hard and stale after being used for a long time, and can also protect the mess. This is mainly because a large number of bacteria have been produced on the rag. Using this rag will bring cross infection. After processing, the bamboo fiber rag does not contain sugar and fat needed for bacterial growth, so no matter how long it is used, there will be no bacterial growth and it has super decontamination ability.

If you want to wipe the rag of glass furniture, you'd better use the microfiber rag. This rag is absorbent, lint-free and soft to the touch!
