I clean my Apple mobile stuff daily with 70% Isopropyl Alcohol. A 1L bottle is pretty cheap and it lasts a long time. I just spray it on a cloth and wipe with that.

I use a glassware/window type Microfiber that I got from the Supermarket. For the Apple Watch, I use a cheap cotton handkerchief from eBay because a Microfiber snags too much on the metal mesh bracelet.

It’s been really effective. The IPA does mean the Oleophobic coating will wear off faster, but it doesn’t last that long anyway and the IPA stops dirt and smudges building up.
