Hah, good luck.
Washer fluid bottles are in the way on both sides, so unless you have spaghetti arms and Phillips tipped fingers, it's faster to just drop the bumper.
After peeling the arch liners out of the way, it's just another 3 screws on each side and 6 clips at the top holding the bumper on. You can leave the undertray attached and just drop the bumper down out of the way, or undo those bolts underneath and take it off completely.
