Paper is usually as white as jade because it is used to carry text and other written information. However, paper is easily stained with oil, making the paper with text worthless. This is a destruction of knowledge. Therefore, it needs to be processed and restored. Let’s take a look at how to remove oil stains from paper. I hope you can understand it. 1. When paper is stained with oil, put a piece of absorbent paper on the oil stain and gently iron it several times with an iron. The oil stain will be absorbed into the paper, making the paper smooth and clean. 2. If the paper is stained with ink, put a piece of absorbent paper under the paper stained with ink, soak the stain with 20% hydrogen peroxide solution, and then put another piece of absorbent paper on the paper and press it with a heavy object. In this way, the ink will be dissolved and absorbed by the hydrogen peroxide, and the ink marks will naturally disappear after drying. 3. If there are damp marks on the paper, you can wash it with alum solution. If it is rust stains, you can wipe it off with oxalic acid or citric acid, then wash the pages with clean water, press them with blotting paper, and dry them in the sun. Note: If you don’t have absorbent paper, use paper towels or more absorbent toilet paper. When paper gets greasy, put a piece of absorbent paper on the stain and gently iron it several times with an iron. The grease will be absorbed into the paper, making the paper smooth and clean. If the paper is stained with ink, you can put a piece of absorbent paper under the paper stained with ink, soak the stain with 20% hydrogen peroxide solution, and then put another piece of absorbent paper on the paper and press it with heavy objects. In this way, the ink will be dissolved and absorbed by the hydrogen peroxide, and the ink marks will naturally disappear after drying. If there are moisture marks on the paper, you can use alum solution to wash it, but please wear gloves and pay attention to safety. If it is rust stains, you can wipe it off with oxalic acid or citric acid, then wash the pages with clean water, press them with blotting paper, and dry them in the sun. People who smoke frequently can also solve this problem by using the remaining cigarette ashes. The main component of detergent is wood ash, which is carbonate, weakly alkaline, equivalent to alkaline flour, and is very effective in removing grease. |
