Clean Metal Security Screens
Security screens are screens that have been specially reinforced to keep intruders out of your home. While a regular screen can be easily pushed inwards or cut through, security screens are normally made from a steel mesh that won't buckle and can be very hard to cut. They come in a wide range of different sizes and options to make sure they work well with whatever windows systems you have in place. Security screens do not require much maintenance but they do need to be cleaned occasionally to keep them looking good.
Dust the screen with a soft rag to remove any loose dirt and dust. Some dusting rags have chemicals that attract dirt to them and these work well for this purpose.
Apply soapy water to the screen using a thick sponge. Scrub with the sponge as much as you can to get the soap into the crevices of the screen.
Use a scrub brush to vigorously remove any dirt or debris that the sponge has not been able to get. If your screens have any special coating on them, use a soft-bristled brush to avoid scraping off any of the coating.
Dry the screen with a towel. You can let it air dry if you prefer since most security screens are rust-resistant but the towel is likely to remove additional dirt as it dries the metal and will make the screen look better.
