Please how do I clean the black ink dots on my fx-570Ms calculator LCD screen?
Sadly, the LCD display is damaged ;-{ Theres not much you can do here as calculators are now throw-a-ways.
Sorry, now nothing can be done. the LCD blackening is irreversible. :’-(
Just get a new one or get a screen replacement for that model…. It’s easy to dismantle the calculator
