In fact, silica gel is not as difficult to clean as we thought. Now let me talk about several methods to clean silica gel:
1. Silica gel can be cleaned with clean water. If it is not so smooth and uneven, we can find a small brush to gently clean it; If cleaning is not feasible, you can apply soap on it for cleaning;
2. If it is the kind of silica gel for heat dissipation, we can use alcohol to remove it;
3. Dip some xylene with a small rinse, dip it in the silica gel, wipe the silica gel soaked in xylene with a paper towel, and finally wipe it with a rag.
