Suggestions for keyboard cleaning products?

Almost all my keyboards are white due to them being vintage, and they attract dirt and dust, especially between the keys. While I have a special plastic cleaner that is alcohol-free and easy to use on most surfaces with a microfiber wipe, I have problem with between the keys

Should I order some specialty kit, or just get some brush from some local hardware store? Makeup brushes don't work very well for this purpose in my experience.
