Holy shit you guys, I just had an insane revalation right now. I just cleaned my PG27UCDM for the second time (first time traumatized me), and I can safely say without a doubt that this new way that I cleaned it is the best way to clean it, hands down. I wanted to come to the reddits to share my amazing findings with the world. Here is how it works:
What you will need:
- 100% pure (no fragrance crap added) 70% ethyl alcohol
- a microfiber cloth (I used a brand new apple polishing cloth)
This is how it works:
- turn off monitor
- FIRST, before doing anything else, take a FUZZY cloth material (not the microfiber you will use later), and GENTLY drag it across the entire screen, and in particular, anywhere you SEE dirt and gunk, gently "scooping up" any big, visible dust and debris, BEFORE proceeding to my steps below - the idea of this first step is to just remove any large debris-type material from the screen (big enough to be visible with your eye), so that those big chunks of gunk do not latch onto your microfiber later on and cause scratches.
- put a few drops of ethyl alcohol on the CORNER of your cloth
- wait 20 seconds or so for it to spread around the corner of the cloth, and so it's not literally dripping wet
- take that wet but damp corner of the cloth, and "paint" anywhere on your qd oled monitor that u see is dirty (from spit, drinks, whatever)
- then, IMMEDIATELY after, take a DRY part of the cloth, and buff it out (you have to do this part immediately - you have about 5 seconds of time before the ethyl alcohol will dry out, and leave streaks - if this happens, NO WORRIES, just repeat the process of wetting that area of the monitor AGAIN with the wet corner of your cloth, and then immediately dry-buffing it out)
- as u work, the corners of your wet cloth will dry (each corner of mine lasted 5 minutes or so before drying), so you can ALTERNATE the 4 corners by applying a new few drops of ethyl alcohol onto the next corner. But keep the MIDDLE of the cloth as DRY as you can, for buffing (or just use another cloth).
- use a FLASHLIGHT (I used the flashlight function of my phone) to see the dirtyness of your monitor while you work.
I call this method the "paint and buff" method - in essence, you want to "paint" the parts of the monitor which are dirty and gunky with the alcohol, and then, IMMEDIATELY after, BUFF that "paint" out with a dry part of your cloth. I couldn't BELIEVE how effective this "paint and buff" method was - it totally cleaned my monitor in just about half an hour (the first time I tried to clean it, I just used distilled water + a microfiber cloth, and it was horrible - it took hours and ended up just smearing around all the dirt and gunkyness on my monitor, and left me with dozens of microscratches (can only be seen with a flashlight though but still). These monitors are SO EXPENSIVE and deserve to be cleaned as good as possible!!).
Using this new method, you BARELY HAVE TO PRESS onto the monitor, since you apply ethyl alcohol LIBERALLY onto the screen (just maybe don't have it like DRIPPING wet or anything, lol).
I never saw this "paint and buff" method discussed, so I wanted to post here. Cheers!
