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.

    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.
