Crazy ex- boyfriend poured bleach into my Yamaha Motif 6 music production workstation keyboard. After discovering bleach dripping from the vents, I never turned it on and it stood untouched for over 3 years.  I replaced that machine, but I'm wondering. Did this caustic liquid evaporate or is it perhaps rusted inside? I'm not knowledgeable about this sort of thing, and Id like to ask, what will happen if I turn it on,  now? Is it best to take it apart first before I attempt to power up, or even let an authorized technician take a look and swallow the expense? Any suggestions based on this information would be great. There is not a lot of info out there about bleach inside the interior of electronics. I'm thinking about trading the keyboard for another piece of equipment
