Using isopropyl alcohol wipes or a cotton swab is recommended for cleaning thermal surfaces in Lenovo products because isopropyl alcohol is effective at removing thermal paste residue without leaving fibers or particles behind, which can be harmful to the delicate components. The use of wipes or a cotton swab allows for targeted application, ensuring that only the intended area is cleaned. This method minimizes the risk of damaging adjacent components or contaminating other surfaces.

Additionally, isopropyl alcohol evaporates quickly and doesn’t conduct electricity, making it a safer option for cleaning sensitive electronics. This is critical when working with thermal surfaces, where the buildup of dust and old thermal paste can impair the performance of heat sinks and cooling systems. Proper maintenance with the right cleaning materials ensures optimal thermal performance and longevity of Lenovo devices.
