How to Refill Your Swiffer Wet Jet Bottle
I found this great tip in an Etsy shop - click here. I hope this works for you!
To refill your Swiffer Wet Jet bottle:
Starting with an EMPTY bottle. Microwave or heat up water in a pot until its very warm, but not quite boiling. Insert the bottle, cap side down and insert in the warm water. No more than a minute or so, then try to twist the cap off. If it does not twist off easily, insert the cap again for another minute or so. After a few minutes the cap should twist off. It MAY be necessary to actually clip the little "prongs" you see inside the cap but I've never had to do that.
Once you have the cap open you can fill the bottle with your choice of cleaning solution!! Vinegar and water makes a good mix, and you can google "homemade floor cleaning recipes" to find TONS of resources. (What you use will vary depending on your floor type.)
Just keep refilling the bottle until its too grungy to use and then buy a new one!!! This cuts down your buying of bottles DRASTICALLY. I can make one bottle last at least a year usually.
