I see tape path demagnetising like insurance. Before playing an important tape, I demagnetise the tape path. Not because I believe the machine is magnetised, but maybe it is. Even a slightly magnetised tape path can erase some signal, and each time the tape is played on that deck the erasing effect multiplies.

Adjusting playback azimuth is a regular thing for me so demagnetising the screwdriver or other driver is also important before getting the tool anywhere near the tape path.

On the other hand manual demagnetising has to be done carefully or we can end up making the problem worse.
