If you're doing a deep clean or trying to remove thermal paste or some sticky residue, isopropyl (like 99%) is the move-leaves zero residue, evaporates fast, and doesnโt corrode your components. Tap water leaves garbage behind and might short stuff if it seeps under components before drying. Dried minerals can also mess up thermals long term. Just get a cheap bottle of distilled or alcohol and do it right, you're not washing a damn car.
