i have been using mechanical keyboards for at least five years, and i always face dust issues. i have to clean my keyboard every month. most of my keyboards are white, so it makes maintenance even worse. i always cover the keyboard with some kind of cloth when I'm away from it. i recently heard about a keyboard rug that covers the whole keyboard and prevents even tiny particles from getting in. what do you all do about this, and is there anything else I can do to solve this issue?
