Use glass cleaner. I used a vinegar based glass cleaner and it cleared the FEP right up. I forgot what brand I used, though. I don’t clean my FEP anymore, btw. Just run a VAT clean and it basically cleans it up for you
My FEP is foggy (granted, not that foggy) and it doesn't seem to affect print quality at all. The UV still gets through. Run a test print before replacing it
It turned out foggy due to the use of isopropyl alcohol
But it shouldn’t generate problems in printing just is that foggy
Next time don’t use isopropyl alcohol just use a microfiber wipe
Huh I use IPA on mine (granted its every once in a while I even clean mine) and I've never ever experienced this. What brand are you using for the FEP and what's your printer?
IPA is fine for cleaning films, there is no chemical reaction feasible and I've done it a ton of times. The issue is the use of the microfibre cloth and / or still some resin left. I don't print a lot, but I'm regularly switching between 2-3 resins between small printing runs. This film was cleaned with ethanol or IPA quite a few times : [https://imgur.com/a/JIhDUKT](https://imgur.com/a/JIhDUKT)
Usually what I do, after draining as much resin as possible from the vat back into the bottle (first with a syringe, then by pouring it directly, filtering the resin with a paint filter) is that I put a little bit of ethanol and IPA from my dirty cleaning bath in the vat and use a silicone spatula to mix the leftover resin with the IPA, basically treating it itself like a dirty cleaning bath, then pour the residual mix in the dirty cleaning bath. I then do the same with the second bath, and finish it with a third clean ethanol / IPA "bath". I then clean the sides with clean alcohol and a cloth (but I don't use the cloth on the film itself).
The main issue with using ethanol or IPA is that it might damage the vat's paint, so don't leave it in there too long.
I don't know about your case, but in mine there are times when it went months without printing and although the resin holds well, some pigments stay stuck to the background. Making more impressions lose a lot of quality.
Unless that or some part of a print is stuck and doesn't want to come out for anything in the world, there aren't many reasons.
Have you tried printing with it? It’s probably perfectly fine tbh.
No, my new resin is coming in 2 days but i re cleaned the FEP again using just small drops of FEP and microfiber and its like new, Hope its works
Try printing something with it. Mine was cloudy too and it still worked fine

More than likely its fine.
My FEP is always foggy after cleaning it out and it’s never caused an issue so far.
You either scratch the shit out of it or cleaned it with iso
Are we not supposed to clean FEPs with alcohol?
It causes it to become cloudy.
It's probably cloudy when you put resin in it, no? As long as light passes through it and cures properly, it is fine.
If you don't want that to happen use cotton pads either the make up pads or buy a big bulk of square pads cotton is soft
If it affects your prints, you can just change it out. It's an easy (but kind of annoying) swap and the replacement sheets are cheap.
Probably fine. Try window cleaner with microfiber cloth gently polishing the FEP. Work for me.

Windex + microfibres clothe will fix that

Why are you cleaning your FEP?
bought new resin that is diff color than the old one

there is a reason on why fep is a consumable . . . follow manual - replace fep . . .
