I used it to clean the thermal paste that I had never changed on my 8-year-old laptop. As you can imagine, it was completely dried out after so many years. The job was done excellently in 5-10 minutes with the help of paper towels and cotton swabs; it evaporates very quickly, and the bottle's nozzle is ideal for dripping targeted drops on a small surface without spilling everywhere. P.S.: It would be good to use it with an open window for ventilation because isopropanol is a relatively dangerous chemical if not used carefully.
