Aluminium MacBook Pros look stunning but they attract fingerprints and grime like magnets — particularly around the palm rests and keyboard area. GT85 is a PTFE-based spray lubricant and water displacer that turns out to be surprisingly effective for cleaning the aluminium body without damaging it. The key is using it sparingly on a microfibre cloth rather than spraying it directly onto the machine, which avoids getting it anywhere near ports, the keyboard, or the screen.
The Cleaning Process
Apply a small amount of GT85 to a clean microfibre cloth and work in sections — the aluminium body, the palmrests, and the lid. The PTFE in the spray lifts grease and fingerprints effectively while leaving a light protective film that helps resist future grime. Keep it well away from the screen (use a dedicated screen cleaner for that), the keyboard, and any openings. A dry microfibre cloth to buff afterwards leaves the surface looking close to new. The whole process takes about fifteen minutes.
Verdict
GT85 on aluminium MacBook bodies works better than dedicated tech cleaning products in most cases — it’s cheap, effective, and leaves the surface with a subtle protective quality that helps keep it cleaner for longer. Avoid it on any rubber surfaces (it can degrade rubber over time) and keep it away from the display. For the aluminium body itself, it’s hard to beat. A useful cleaning tip that cost almost nothing to discover.
