Screen removal for cleaning

Duplicate

Most usually just push up against 2 springs until it is high enough to remove from the bottom. Just a hint, open the sliding window first then slide the screen open about 4 or 5 inches, then put upward pressure on the screen frame, either on the top of the frame or wherever, keeping in mind you have to compress 2 springs in order to get the screen high enough to remove the bottom.

Usually just push up and lift out from the bottom.
I use a small vacuum clear with a hose on it. Sometimes one of those Micro Fiber towels. Than you do not have to remove them.
