Razer Laptop Keyboards Question

Does razer put grease or something on the metal bars that are underneath some of the keycaps on their laptop keyboards, because one of my keycaps broke off for my razer blade stealth, and in trying to fix it, I touched the bar and could have sworn I got something on my finger, however my friend touched it and didn't feel anything. So does anyone know if I am right and they do put stuff there? (As much as this kind of a joke/help-me-settle-a-bet post I did proceed to type on my laptop after touching it and would like to know if I need to clean the keyboard to remove the grease residue or whatever that was on my fingers. /https://xender.vip/
