so I spilled wine on my keyboard. I have cleaned the inside with isopropyl, as well as cleaning all the keys and allowing them to dry. it now works fine, apart from a bit of a smell. However some keys stick in and are stiff. I have tried the hot water and straw method which works for a few hours, however the keys go back to being stiff. I'm thinking that I might have to re-lube some of the switches, does anyone know of any which are safe for using on keyboards?
