First, read the English article below.

You only need to do this when you have a lump of sap on your clothing. It won’t come off easily unless you freeze it. Throw your clothing in the freezer or pack some ice in a bag over the sap. After a few minutes, it’ll harden. Get a blunt butter knife to avoid cutting your fingers or your clothing. Hold the knife flat against the fabric and scrape it over the gob of sap. Be very careful when using the knife. The frozen sap should be brittle and break easily, so you won’t need to push hard. Moisten an old rag, hand towel, or cotton ball with the alcohol. You can find bottles of isopropyl alcohol at any drug or general store. If you don’t have it, you may use an alcohol-based hand sanitizer or hair spray instead.  Rubbing alcohol is effective in removing sap from your hair and body as well. For leather, try saddle soap instead. A little bit of peanut butter may also work without damaging the leather. Blot the area with the damp towel. If you put a little rubbing alcohol on the spot directly, you can also rub it in with your finger or an old toothbrush. You’ll most likely see the alcohol dissolving the sap stain immediately. For large spots, you’ll need to apply more. Use the rag again or apply extra alcohol directly. Rub the spot until it fades. Wash the clothing as you normally would. You can put it in the washing machine and use your regular detergent. For the most effective cleaning, get the water as hot as it can safely be for the fabric you’re treating. To find this, look at the label on the clothes or search the fabric type online for recommendations.
