Help with cleaning keyboard and trackpad?

[JakobAloudMadge]

I haven't spilled anything on my MacBook Pro Retina "13, and I usually wash my hands right after I eat anything and before I use it, but the keys and mousepad just have a "dirty" and non-smooth feeling to them right now. What is safe to clean with? Thanks.

Isopropyl (rubbing) alcohol is what I use with a microfiber cloth. Don't soak it, and let it dry before closing the lid.
