Begin by vacuuming your porch screen clean of any debris or pollen. An upholstery attachment works best for this, which has a soft bristle brush on the end.
If you have access to the outside of the screen, start there and vacuum the outside first, then move to the inside and finish vacuuming the screen.
Fill a pail with warm water and a few spurts of dish soap. I don't usually measure, as just a little soap is necessary. Otherwise, you'll be wiping soap suds away for the next hour (not fun!)
Dip a clean washcloth into the soapy water and gently wash the screens.
Finally, wipe the screens clean using a fresh bucket of warm water and a clean rag.
Notes
I’ve included detailed pictures of each step in the post above for visual reference if needed.
You may worry that you’ll cause damage to your porch screens if you clean them, and of course, there is a risk of that if you press too hard or are overly rough with your cleaning arm! (So go gently. That’s my best advice.)
I prefer to use microfiber cloths to clean porch screens as they are far softer and help lift off dirt and pollen.
Sometimes, mold spots develop on porch screens. If this is the case, be sure to remove any mold before continuing.
You can use a hose and spray nozzle to clean porch screens from the inside out, but be careful to avoid spraying your furniture!
Any liquid dish soap will do for this cleaning method.
It’s best to clean porch screens at the beginning of Spring. This is when it’s not freezing cold outside (yay!) and where you’ve got the highest chance of sunshine before the summer comes to help your screens dry out naturally.
