I moved into a place with one very hazy window screen that is difficult to see through.
I have tried scrubbing it with a brush with soapy water and blasting it with the hose. But I cannot get rid of the hard material buildup. I even tried dipping a brush in CLR and scrubbing the screen.
When I Google how to clean a window screen, I just run across people telling me to do what I already tried. But I think the people touting these methods simply have screens with dirt in them.
This doesn’t seem like simple dirt buildup. I enclosed a close up photo of what it looks like.
I bet if I poked all of the holes individually with a toothpick I could clean it, but that would take eons. Any advice? Thanks.
I’m still trying to wrap my head around what it actually is. Never seen anything like this but just replace it. Perhaps update with a wider shot of the full screen panel
I didn’t bother posting a wide shot because you can’t tell what it is from so far away. It just looks like it’s hazy from dirt. But actually I was able to pick some small hunks off with tweezers and it has an appearance and consistency similar to dried glue. It’s slightly white and semitranslucent. It is also only present on the interior surface of the screen.
But as requested, here is a wider shot comparison of the normal unaffected screens (top) with the affected, coated screens (bottom). https://imgur.com/vurLJvw
My running theory is that something was glued to the screen at some point, perhaps to deflect sunlight. Or the screen was coated in something, maybe to try to further prevent the intrusion of bugs.
It looks like some sort of padding that weathered into the screen. As many have commented you can easily remove the spline and replace with fresh screen. It’s not expensive and don’t require much too much precision. Following an online guide for measuring will be sufficient. I replace my window screens as needed and a standard house window takes about 15 minutes. The context of the wider shot does help! Thanks.
I feel like this is the answer. The amount of work to clean the screening will probably be about the same amount of effort to just replace it. Some local hardware stores will even do it for you (not the Home Despot)
Even if the OP manages to clean it the screen will probably be brittle and may break.
Maybe compressed air?
I would try a brush a sparse and tough bristle. Like a whole bunch of toothpicks at once
First off. This picture is vile and while I appreciate your need for assistance, you have ruined my day and I will be busy puking for the rest of the week.
To answer your actual question: I recommend just replacing it. Extra screen and cord is cheap and easy to install.
It’s an incredibly large screen that goes to my back porch. I’m not sure that the window frame itself is easily removable. Would that make it tricky to install a new screen with something that large and not movable?
There are a lot of videos on YouTube about how to replace a screen. Most of them that I have seen have a pane that only works once and then when you remove it, you replace it with rubber tubing that they sell from the store. They sell a special tools kit to pry the original pane off and some rollers and clips to get the screen back in nice by pushing the tubing into place without the groove. I recommend cutting a piece of wood to the exact spacing that the screen needs to maintained since making the screen tight can warp its profile and not fit correctly.
The screen should come off from the window frame - it is mounted in its own frame made of lightweight metal.
It’s like $20 in tools and new screen to replace. Best to start on a smaller window for practice, but once you’ve done one, they go easy.
The frames to the screens immediately above this are easily removable, but I can’t seem to figure this one out. Is it a bad idea to try to replace a screen without removing the frame?
It’s not exactly a window. It’s a component to a screened in porch.
You probably can, just need to find out how the screen is attached. Usually it’s a rubber “bead’” that has been pressed into a notch to hold the screen. Just make sure to replace the bead too when you replace the screen.
Have you tried warm/hot vinegar in a spray bottle? If you have hard water it could be mineral buildup and some warm vinegar would help dissolve it. If it’s not from hard water it may be trickier, but a super soft bristled brush and some simple gree or other cleaner may work as well.
Carefully if it’s a metal screen vinegar could corrode steel screen… Though it’s probably worth a shot it the alternative is replacing it.
Just get new screen or
Completely agree. Takes about 5 minutes per screen and often you can re-use the bead around the edges.
No kidding, I stared at it for a minute going “is this going to set it off?” and when my brain finally decided it couldn’t come up with an explanation it launched hard into the skin crawling, scalp itching and nausea. It’s like visual kryptonite.
Pressure washer should help. One of those basic electric ones should be enough.
Sounds like it’s time for a new screen
So I was playing around with some tweezers and it actually seems like I can peel it off with some difficulty, although it comes up in pieces. Considering none of my other screens look like this, I’m wondering if it is actually some sort of purposeful hazy coating that got destroyed over the years??? Is that a thing??? It only seems to be present on the inner surface of the screen, not the outer side. Scrubbing does nothing to it put it can be peeled off it seems. Just gonna take me forever to do.
That’s an interesting thought, is it a screen that faces a sun side? Might have been a coating that helped reduce sun intensity. Could be the outside peeled off and the inside hasn’t yet.
Like others have said, replacement is probably your easiest solution. As long as you can see the screen cord it shouldn’t be too difficult to do in place, but would definitely be easier if you can remove. Start at the top corner, work your way across then work your way down. Let gravity help.
Yes, it does seem to be a side facing the sun.
Interesting to note, but the previous tenants seemed to have a thing for blocking out all sunlight for some reason (which quite frankly was pretty minimal to begin with due to the adjacent forest). Perhaps they were vampires.
The upper panes had black plastic films glued to them to reduce sunlight, but the panes were not glued to the screens themselves so they were easily removed. There is no such plastic film present on the lower pane, but perhaps there was at some point and this is the leftover glue.
My first guess is a smoker who didn’t want to go outside.
Maybe, but there are many screens to my porch. This is the lower most screen. You’d think because smoke rises that the upper screens would be affected. This is the only one that looks like this…and it is diffusely and evenly coated on the inner side of the window.
In peeling some of it off, it has the consistency and appearance of dried glue actually. Not sure if that’s actually what it is or not though.
This is a weird question, but I don’t suppose this is near Baltimore, or a previous owner was from near Baltimore? They have (or had, not sure how popular it is anymore) a thing there, where they paint their screens with various scenes. It reduces visibility, so people can’t see in as well, but still lets air in. So I’m wondering if this is a very dirty old painted screen, with maybe the pores clogged up.

Painted screen society of Baltimore, with images:
http://paintedscreens.org/This is very interesting. No, I do not live near Baltimore and the coating is just diffusely white and semitranslucent, without different colors.
But I do think a coating must have been put over the screen at some point, be it paint or not for whatever reason.
These look pretty interesting and if it was a picture I would just keep it lol
Damn, I only lived in Baltimore for a year but I loved it there. I’d forgotten about these!
This is so niche I love it. Thank you for sharing this little fact.
Edit: and there seems to be different colors on the screen, making me think your theory is quite possible.
The different colors seem to just be image compression artifact. The screen is diffusely coated by a white and semitranslucent material that seems to have a similar consistency and appearance to dried glue (I was able to pick some small hunks off after viciously rending it with tweezers lol)
test a few cells on the inner surface with q tip of rubbing alcohol? might outright melt both the screen and the crud but could maybe help wipe it away
Close the window then get a high pressure hose/washer and spray it until it’s clean.
Pressure washer? Might be overkill, but if you get one with enough horsepower it could do the trick.
This may be a bad suggestion, but if the screen itself is made of metal, maybe you could burn off the film
😈😈😈🔥🔥🔥
Something strong like CLR or Citric acid might get rid of it
is it from wildfire smoke?
I’ve worked in a lot of kitchens and carbon build up is one of the worst things to remove. Might be best off replacing it as others said.
Hot vinegar will remove sugars. Rubbing alcohol or other solvents will remove oils. For burned carbon we used something called carbon off which is very caustic because we’re also made of carbon.
Doesn’t seem likely. This is the only pane affected. And the material seems to be coating the inner part of the screen, not the exterior part.
Pack your bags and move away.
Shall I pack onions as well?
Any uniqueness to your climate or location? I see a lot of green in one of your photo backgrounds, could this be built up pollen and dust bound by minerals from the rain? Maybe combined with the residue from other cleaning attempts.
I would try a bristled scrubbing brush with dish soap first. If that didn’t work, I’d try the brush with a weak vinegar to see if it’s a pH issue.
I totally thought this was going to be a bunch of little cans of beans when I zoomed in.
I was going to say replace it but you replied to someone above saying the same thing. I still say just replace it but by buying the material, which can be bought cheaply in rolls, and reuse the frames
