Do you own a swiffer dust mop? Then why are you buying those expensive pads for them? They are high priced and if you buy the generic ones, they don’t work. Well, there is a solution. And believe me it’s too simple. Grab a couple old washcloths or wash rags. Or better yet, crochet a square that fits around the flat end of the mop.
For a duster, simply take a rag and drop a bit of fabric softener on it. mash it around a bunch and allow to dry completely. Once dry, and this may take a day or so, wrap around your swiffer and press into the holes and dust.
For a mop, simply take a rag and get it wet with hot water. Spray some soap of your choice over it and mash it together. Ring it out, but not all the way. The rag must be wet. Mop away. I’ve even had to add water to the rag as I go. This dries pretty quick.
