In 1992, I built a PC for a friend's CAD/CAM work. When I installed it, I told him to clean it out with an air gun, twice/year, making sure that he cleaned out the PSU too. Last time I was there, about 5 years ago, they were still using it. They had the Hdd upgraded several times, and replaced the CPU fan when it started groaning. Going back 40 years, in another life, we regularly got field returns from two sites. One was a coal mine, the other, a biscuit (cookie) factory. We would put them straight in a basin of warm soapy water, overnight to get rid of the coal dust and sticky sugary residue, then leave them in a warm dry place for a few days, before we would even test them. On one occasion, one of the field techs returned a replacement cage fan saying that it sucked instead of blew !
