Clean and wipe down the door especially on the door handle side edge and the bottom edge of the door.
Measure the length of the bottom of the door. Measure the thickness of the bottom of the door. Choose a vinyl door wipe with a matching thickness.
Cut the vinyl door wipe to the length of the bottom of the door. Clip the vinyl wipe onto the bottom of the door so that the thin "wiper" section is hanging downward. Proceed to Step 4 if water leaks from the side of the door as well.
Measure the height from top to bottom of the one edge of the door, the side with the handle on it. Measure the thickness and choose a vinyl wipe with the same thickness.
Cut the wipe the same length as the door height. Attach the wipe so that the "wiper" section is facing away from the door. Open and close the door to ensure the wipe does not stick.
