Were you scrubbing an mfin cheese grater with it? I have not had this problem

They’re decent sponges that last a long time and don’t get smelly very easily, and they’re also cute.

In my experience they’re a bit lacking in abrasive power though.

To be fair, the Fahrenheit measurement should be pretty intuitive here. Fahrenheit is easy because 0 degrees is “really fucking cold” and 100 degrees is “really fucking hot.” So anything triple-digits should be easily recognizable as “yeah that’s way too fucking hot for a phone.”

This is also why I prefer Fahrenheit to Celsius in general (even though I am an engineer and am not a die-hard patriot or anything like that). It is a more practical scale for everyday usage.
