Debate: That repair shop guy who said to never use Q-tips for sensor cleaning

Had a guy at a shop in Seattle tell me last year that Q-tips are fine for cleaning sensor dust if you use the right solution. I went with the rocket blower for months after that, still had spots. Finally tried a proper swab kit last week, but now I'm wondering if he was right that Q-tips work in a pinch. The spots came off fine with the swabs, but I burned through three of them for one sensor. On the other hand, I've seen people gum up sensors with cotton fibers from cheap Q-tips. So which side are you on - are Q-tips a legit option or just a shortcut to a damaged sensor? Anyone else have a shop guy give you advice that split the room like this?

Yeah...glue residue sounds like something I'd accidentally do.

Here is the thing nobody talks about: cheap Q-tips shed fibers but the real risk is the glue holding the cotton together. That glue can dissolve with sensor cleaning fluid and leave a sticky residue that traps more dust than you started with. A proper swab is a single use sealed piece designed to not break down chemically. The shop guy might have been thinking of the old days when sensors had a protective glass cover that was tougher, but modern sensors are more delicate. Saving ten bucks on swabs is not worth the headache of a smeary residue that a rocket blower cannot fix.
