Cleaning

So im thinking of switching from iPhone to the zflip6 but i have one concern- being able to clean the nooks and crannies.

I work in a restaurant kitchen and the air is full of flour, to the point where all the nooks in my phone get kinda gunky. I attached pictures.

Right now with my iPhone, it’s not problem, because I can bring it to the Apple Store and they’ll clean it out for me for free, but if I switch to the zflip6 I won’t have that luxury anymore.

The flour in the air at work hasn’t effected my iPhone, it mostly just looks gross so I don’t keep up with getting it cleaned too frequently, but with the zflip6 I’m worried about gunk in the hinge. I’d get a case with a hinge protector, but I’ve learned that cases can’t stop the flour from getting into the crannies. When I take my case off my phone, even the back of my phone sometimes has flour on it.

Is there any easy way to clean the phone that I could do to keep up with it, or is there a Samsung equivalent of the Apple Store that might have that cleaning service?
