Soap leaves a filmy residue behind which now acts as a barrier between the adhesive and the metal door. Isopropyl alcohol is recommended because it evaporates and leaves no residue. Or just plain water can be used but please wait for the water to dry before applying the adhesive. SCREEN DOORS - This product is not intended for screens, there is not enough screen for the adhesive to adhere to. The screen is more than likely dirty from dust and debris. One suggestion for screens - If you clean the screen using the process above and place Scratch N Scram ON BOTH SIDES of the screen, the product is basically sticking to itself. this should work for a screen door in this scenario
