Will taking off the keycaps to clean them + putting them back on injure the Neo 2?

I'd like to take the keycaps off, give it a nice clean and am even thinking about painting the keycaps, but I know some keyboards don't like their caps being removed and will re-attach a bit wobbly or loose. Has anyone done this and does it affect the quality of the typing afterwards?

Also I'm thinking of painting the keycaps, or replacing them with a more "aesthetic" version! Does anyone know which paint to use on keycaps (so it's not sticky or rubs off when typing) or which style keycaps will fit the Neo 2?
