Cleaning dried thermal silica gel can be challenging, as it tends to adhere strongly to surfaces. However, here are some steps you can follow to clean dried thermal silica gel:

1. Soften the Thermal Silica Gel

Begin by attempting to soften the dried thermal silica gel. Apply a small amount of heat to the gel using a heat gun or a hairdryer set to a low heat setting. The heat should help soften the gel and make it easier to remove.

2. Physical Removal

Once the gel has softened, use a soft brush, such as a toothbrush or a non-abrasive brush, to gently scrub the affected area. Be careful not to apply excessive force that could damage the surface. Gradually loosen and remove the softened gel by brushing in a circular motion.

3. Solvent or Cleaning Solution

If physical removal alone is not sufficient, you can try using a solvent or cleaning solution. Some suitable options include isopropyl alcohol (IPA) or a specialized electronics cleaner. Moisten a clean cloth or cotton swab with the solvent or cleaning solution and gently dab the dried gel. Allow the solvent to penetrate and loosen the gel, and then gently wipe it away. Ensure that the solvent is compatible with the surface you are cleaning by performing a spot test in an inconspicuous area first.

4. Repeat if Necessary

Depending on the severity of the dried gel and the surface material, you may need to repeat the process multiple times until the gel is completely removed. Be patient and persistent while avoiding excessive force or aggressive cleaning techniques that may damage the surface.

5. Rinse and Dry

After successfully removing the dried thermal silica gel, rinse the area with clean water or wipe it down with a clean, damp cloth to remove any residue from the cleaning process. Then, ensure the surface is thoroughly dried before reapplying the thermal gel or using the component again.

Remember to always follow safety guidelines and refer to the thermal pad manufacturer recommendations for cleaning procedures, as the specific instructions may vary based on the type and formulation of the thermal silica gel you are working with.
