Refill Swiffer Wet Jet

My mother-in-law just ran out of fluid in her Swiffer Wet Jet cleaning bottle.  So, I found a screw/bolt, matched a drill bit to the size.  Drilled a hole in the opposite end from the one that gets inserted.  Filled with Pine-Sol and water.  Screwed the bolt in (no leakage when right side up).  No need to remove the original lid.

Similar to this but only one hole drilled.  Less chance of spillage.
