It looks like the oleophobic coating has worn off my s3. What’s the best way to clean oil/fingerprints off the sapphire crystal screen? A microfiber cloth still leaves a haze. Maybe wetting the microfiber a little?

I just use the 3M microfiber cloth and a little condensation from my breath. I change them out often too so I don’t get a bunch of gunk built up from previous cleanings.

Since the oleophobic coating has already essentially worn off as you noted, you could use a slightly damp microfiber cloth with a very minimal amount of isopropyl rubbing alcohol, that should remove any remnants of smudges and fingerprints.

I just rub it on my shirt/t shirt or whatever. I thought sapphire was meant to be tough. It's survived since 2015 or whenever the series 0 launched.

That's not a good idea. Even though the sapphire glass is scratch resistant it's still much better to use a microfibre cloth.

I’ve had Rolex since 2010 and have rubbed the crystal with my shirt since day 1. Zero issues. Same with all 3 sapphire AWs. Same with every other sapphire crystal watch I’ve owned.

To the OP, you’re asking how to get the fingerprints off of a touch screen watch?

A cotton T-Shirt should be fine as long as you shake it out to make sure there isn't any sand or grit on it that might scratch the crystal - same applies to a microfibre cloth that not everyone carries with them at all times.

Rubbing your shirt on a sapphire display is not going to affect it, in the case of the Apple Watch, it would only affect the oleophobic coating, which are two different things.

I've always cleaned every Apple Watch I've ever owned on my shirt or pant leg, whether it be sapphire or not, and never gotten a single scratch that way. Now if you're a construction worker, I wouldn't recommend that :)

I suspect all you people who use your shirt or t-shirt think you don’t have any scratches but I would be surprised if you didn’t have micro scratches probably barely visible or not at all to the naked eye.

I use a microfiber cloth wetted a bit with distilled water to clean the entire watch (sweat off the back, fingerprints and other smudges elsewhere, including the sapphire screen). It takes everything off without any damage.

I just run my watch under water, rub it with my finger a bit, towel dry and then polish with a microfiber cloth. Other times I just use my microfiber cloth.
