Patty from Michigan asks: In your book Dining on a Dime, in the cleaning section, it has a recipe for making the floor cleaner for the swiffer. My question is how do I get it into the bottle? The top doesn't come off, so, the only thing I can figure out is to put a hole in the bottom, which when turned upside down to use, would be at the top. Also, I don't know if this bottle needs to be air tight. Anyone know?

Jill: When I refilled my bottle the first time, it was very hard to open and I had to really force it. If that doesn't work then they may have changed the bottles. I don't know all the ins and outs on those bottles but if you can't get the lid off then your idea of a hole on the top sounds like it might work. If it needs to be air tight then you maybe could place a piece of tape over the hole. Hope that helps.

From A Reader: We had some large syringes left from our late cat's final illness when he wouldn't eat. The tip was large enough to deliver liquefied food into the side of his mouth, and the syringe itself holds 60 mL/2 oz. liquefied food. So, I got to thinking.

I added some Pine Sol to water in a measuring cup, loaded the syringe, and carefully squeezed it through the hole into the reservoir bottle that gets punched when you first load it into the Swiffer mop. The mix went in without a hitch, and I was able to fill the bottle at a cost of about 10 cents. With a replacement bottle costing $4.60 or so, that's quite a savings.
