@jens I think that only happens if you smoke indoors?

(Cooking fats/oils that aren't vented adequately also do that, yes.)

@jens Ah yes, though thankfully it doesn't get sticky.

It makes all the difference when one can just use an electric duster to clear it out without anything more complicated (do that while wearing a respirator either outside or inside with an air purifier working, that amount of fine dust in the air is not good to breathe).

@lispi314 Yeah.

I used to work in a computer shop back around the turn of the century, sadly pre-smartphone times, or I would definitely have taken pictures of the odd computer insides.

I am still impressed with one computer that came in for servicing because it "just stops working after a while". The nicotine yellow case should have warned me, but I still wasn't prepared for what I saw.

The *entire* case was full of fluff, no space left. The CPU fan couldn't turn, and even if...

@lispi314 ... it could have, there wouldn't have been air to push around.

A hoover "repaired" it.

Still, I'm kind of impressed with the engineering, though. It's is a lot of abuse that this machine endured.

I'm so impressed, I still recall the company of the client. Their business was related to computers...
