slap a case on, I know not the greatest idea but at least it will keep your phone safe and clean

a case is a good way .... or a soft microfiber cloth with a light disinfectant spray... on the cloth not the phone

@CodyH  yes good idea to have a case for your device which will help,  remove this when cleaning though.   Best advice is to use a microfibre cloth with a small amount of cleaning solution or water.   Apply this to the cloth, never directly on device.    More details here https://eu.community.samsung.com/t5/community-newsroom/how-to-clean-your-smartphone/bc-p/2061800#M22...

New screenprotector and also case, and even so use microfiber towel or smtg and clean it Time by time with a solution for screens or pure alcohol, it should help you best regards Alex 😉
