Metal needle removal method: You need to prepare a metal needle or toothpick (the thinner, the better), and an eraser. Pay attention to gently lifting it from one end (be careful not to exert force in the direction of the object being attached, but be sure to exert force outward). In this way, it is possible to pick off a larger area at once (don't let the dropped labels fall on other things, otherwise it will become secondary pollution). There will also be residual glue when the strength is different. In this case, just use an eraser to wipe it gently (pay attention to the location where the eraser falls). Nail polish remover removal method: spare nail polish remover and cotton swabs. Apply a small amount of water to the overall fragile label and use your fingernail to gently scrape off the label that will peel off. Then use a cotton swab dipped in a small amount of nail polish remover and apply it to the remaining glue on the label. After 1 to 2 minutes, the remaining glue will fall off if you gently rub it. These methods do not damage the object being attached and can cleanly remove the self-adhesive labels.

The principle of using rubber: rely on the rubber to fuse the self-adhesive glue. Method: Use an eraser to wipe continuously. The areas with glue will turn black at first, but after rubbing for a long time, the glue will slowly fall off. Advantages: easy to operate, quick results Disadvantages: average effect. Edible oil removal method: Reserve a spoonful of edible oil, and then apply it evenly to the place where the label is attached (fragile labels will lose their stickiness under the action of oil). After 3 to 5 minutes, you can slowly peel it off from the corner of the label with your hands, so that no trace of the label will be left. Use the lemon juice principle: the principle of similarity and compatibility. Method: Squeeze lemon juice onto the hands that are stained with stickers, and rub them repeatedly to remove the sticker marks. Advantages: Suitable for removing stickers stuck to hands without causing any harm to the skin. Disadvantages: Not effective in removing adhesive from other objects.
