How to get my window screens really clean?

Take them out one by one in order and wash yourself. A bucket with some dawn dish soap, a car wash sponge and hose is all you need. Rinse with hose then ser in sun to dry, then replace in order taken down, but I would wash the windows inside and out first.

Power washing never releases all of the dirt. Want proof? Wash them then run a white rag across them. You will see dirt. The dirt clings to surfaces and unless you wipe the dirt to loosen it surprisingly a lot will still remain attached to surfaces. A soft rag gently run across both sides with dish detergent water will do the trick. Then rinse and put screen back in.

Hi Betty. I remove mine and use a gentle sponge and soap water and scrub them down. Then rinse them and let dry. I do mine out side but you could also do them in a bath tub. Good Luck!
