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.
Soap and warm water, along with a brush. You'll need to scrub it a bit, and to keep things soapy. Be careful not to push too hard and stretch out the screen. Spray the screen off with a hose when finished scrubbing. Repeat as necessary.
I use a window fan at home, and the screen gets gunked up. Just takes some soap and a little elbow grease to get it clean.
