How do you clean your hifi equipment, speakers etc?

Probably been discussed before.. But how do you guys clean your hifi setup, speakers, connection behind your amp for instance? Do you only do as the manual says or do you just use some mild soap? I’ve heard people that use cans with air to clean their amp as an example free for dust. Dynaudio for instance says if you’re very careful you can wash the speaker drivers with a cloth with some water. I never touch the speaker drivers.
