The grills come off and people have suggested using a dry cloth to clean them. Microfibre clothes I had are static-y and "sticky" when i touch them. Would this be effective you think in removing stuff like lint and dust?
I'm just afraid of the cloths being too static, and causing inadvertent damage to the speakers themselves (E.g. once I put the grilles back on, after removing them)
And which vacuum type is good? Will the suction be too strong--which hose attachment, if any?
I think a vacuum cleaner is your best bet. Wiping a fabric surface with a cloth seems strange to me at least. Maybe a lint roller as was suggested. I think you're overthinking this in general. Just use a vacuum attachment for either fabrics or crevices or the basic hose...your pleasure.
I have OCD (now I'm embarrassed), and so I don't know the "right" way or proper way of cleaning speaker grilles. I'm very particular, and when there is a "best" way, I will always use this way. So I will be trying the vacuum w/soft bristle attachment.
Last question, but will the hose suction be too strong or would it be good without warping the grille/cloth?
Unless your speaker grills are of very low quality I wouldn't worry about the vacuum. Don't press the nozzle/head/attachment into the speaker so as to press into the tweeter dome or driver, etc. OCD isn't so bad, there's worse.
I have noticed dust and likely dead skin cells on my speaker grilles, and I vacuum once a week.
Is the best way to remove this stuff without damaging the grilles to use a microfibre cloth, feather duster or a hand vacuum?
Do any of you go further, and even handwash with a detergent/soap?
I use a vac with the soft brush attachment. I also use a soft shoe brush on speaker grills. It also works wonders on remote controls and face plates.
