I have a back porch that is all screened in, they are so dirty inside and out. The porch has quite a bit of furniture and etc on it. Is there a special way to scrub them clean.
Please HELP.

Are you saying the screens are not removable and there are no windows? If that's the case, I would use a pail of soapy water & a soft scrub brush & then rinse down gently with a hose - from the inside of the patio. That way you are not spraying toward your furniture.

In a pinch you can vacuum screens but washin is better.

I used a spray bottle filled with vinegar water and they came clean as a whistle and looked like they disappeared. You can wet with plain water and a sponge and then spray from the inside out and you will be pleased with the results.

Yeah....what she said! I use bleach water with some Lysol cleaner.
