The TouchID sensor on my iPhone 7+ always seems to be covered in a greasy fingerprint, even though my hands are clean. I wash my hands frequently throughout the day (germaphobe), but every time I use the touchID sensor, it just leaves a greasy fingerprint.

It used to be solved with a simple wipe with a microfiber cloth, but now, it seems like it takes a vigorous rubbing with that microfiber to remove the fingerprint.

So every time I want to log in now, I have to clean my fingerprint sensor.

Is there any way to re-coat the oleophobic coating? Was the touchID sensor coated before?

In the middle of several books.
To my knowledge, there is no coating with the Touch ID like there is with the screen.

what kind of soap(s) and cleaners are you using to wash your hands with? It is possible, that there is residue from the cleaning building up (easily) on the sensor.

Interesting. I'll keep an eye out on the soap and rinse better. But I don't think it is.

I believe you're correct. I attempted to research this topic. From the visiting forums I researched, there is no oleophobic coating on the Touch ID button/sensor, which others said it would interfere with the registration. Also, the Touch ID button has a sapphire coating over the button, which would also be a factor.
