\"MacBook<\/a><\/strong>MacBook cleaning means taking the machine apart and removing the dust from the inside, not blowing air through the vents: compressed air will not get the dust out, it only comes out once the computer is open. This is worth doing once every two to three years.<\/p>\n

Laptops arrive here so neglected that the letters on the keyboard are no longer visible under the grime. Crumbs under the keys, a thick felt of dust and hair inside, the fan still spinning but no longer cooling anything. The owner is convinced everything is fine \u2014 the computer turns on, after all.<\/p>\n

What happens inside without cleaning<\/h2>\n

Dust does not settle in an even layer. It packs into felt and sits on the heatsink fins on the fan side, exactly where the air is supposed to pass. Nothing shows from the outside, the case is closed, and the airflow is already near zero. That is where the noise, the overheating and the sudden shutdowns come from.<\/p>\n

Then comes the part that makes cleaning more important than it looks. Dust holds moisture against the pads, metal traces and contacts of the board. The moisture triggers corrosion: the metal breaks down into particles, and those particles short neighbouring pads and contacts to each other. This is a board that had not been opened for years:<\/p>\n

This corrosion builds up slowly and quietly over years. Spilled coffee is a different story \u2014 that damage is instant, and it is dealt with separately: what to do if liquid was spilled on a laptop<\/a>.<\/p>\n

How often MacBook cleaning is needed<\/h2>\n

There are two kinds of work here, and they should not be confused.<\/p>\n

Routine<\/strong> \u2014 once every two to three years, roughly like servicing a car every ten thousand kilometres. Dust removal, a general inspection, cleaning the screen, top case and keyboard, plus small fixes as needed.<\/p>\n

Full<\/strong> \u2014 when the machine has been ignored for years and the board is heavily contaminated. Complete disassembly, ultrasonic board cleaning if we agree on it, thermal paste replacement, and repair of whatever the inspection turns up.<\/p>\n

The intervals are not rigid. In a flat with pets, next to a construction site, or where people smoke, MacBook maintenance is needed more often. In a clean air-conditioned office a machine comfortably goes four years untouched.<\/p>\n
