How to refill a swiffer bottle

This has saved me so much money and time.  I tried all different ways to get that thing off.  I then saw on Pinterest a way to remove it quick and easy.

Fill a measuring cup up with boiling water and dip the tip of the swiffer bottle(the screw on cap side) in the hot water(make sure it is boiling).  I let it sit there for a  minute or so and remove and turn the lid.  It screws right off.

I fill mine with vinegar, water, Shaklee basic H, and a little Isopropyl alcohol.  Works great!
