Yeah it's long a careful undertaking. You basically have to remove the touchscreen glass from the monitor and clean it on the inside. I've never done it with a 32 inch screen. Largest I've ever done has been 24 inches. The touchscreens are usually taped to the assembly with double sided foam tape. The tricky part is to remove the screen without breaking it or damaging the sensors on the edge. I've killed a couple of 20" bally touchscreens doing the procedure, so be very careful and take your time if you decide to do it.
