95% isopropyl alcohol works well for removing thermal paste from CPUs and GPUs. You don’t need 99% to achieve the job.
Over 90% is acceptable. Directly applying alcohol can cause more damage. Start by wiping the residue with a dry paper towel over a trash can. If it’s sufficiently dry, it will break apart easily and leave minimal leftovers, which you can then remove using alcohol and a clean towel.
