Hi Ling Ting, thank you for your question about cleaning and maintaining the eDegree FS1 Electric Scooter Stem. To keep it in good condition, we recommend wiping it down with a soft cloth and mild soap after each use. For more thorough cleaning, mix equal parts water and white vinegar in a bowl, then dip a cloth into the solution and gently scrub the stem. Make sure to rinse it thoroughly with clean water afterwards. Regular maintenance will help extend its lifespan. Would you like any specific tips for handling scratches or other minor damages?
