In this, my first instructable, I'll show you how to remove that pesky cap on your swiffer wet-jet bottle that makes it impossible to refill and causes you to buy their overpriced solution. All you'll need is a pair of fingernail/toenail clippers and a pot of boiling watter (and the bottle of course).
Step 1: Removing the Cap
In a small pot, bring just enough water to cover the cap to a boil. Once you've brought it to a boil, place the bottle, cap first, into the water. After about a minute and a half, remove the bottle from the water, and give the cap a good, hard twist. It should pop right off as the boiling water will have softened the plastic cap.
