I love our Swiffer Wetjet for cleaning up small messes and quick cleans in between scrubbing, but the refills are so dang expensive. I do love the smell, but not worth the 5 bucks a refill. It’s actually really easy and you can fill it with whatever cleaner you want. Swiffer wants you to think that the cap is permenant, but it can be easily removed without even much elbow grease.
Step 1: Remove the cap. Almost everyone probably has a pair of these standard pliers or channel locks like it, if not… borrow some from your dad or uncle or neighbor.
Step 2: Refill. Once you have it off, just fill it up with whatever cleaner you like. Pine sol smells good or in this case I used about 1.5 cups of vinegar and topped it up with water. Whatever floats your boat so to speak.
