Clinley's magic sponge eraser is simply the best helper for housewives. Every small white square is nano sponge, and the tiny molecular structure is easily fused with dirt and dust, and falls off when it meets water. The most convenient thing is that you don't need any emulsion, and you can easily remove dirt with a little water. Whether it is the keyboard in the office, the pots and pans in the kitchen, the sofa in the living room or the faucet in the bathroom, it can be cleaned. This sponge saved me.
