I'm not big on conventional cleaning products. Yes, paper towels are helpful and those disinfecting wipes can come in handy, but I'm not big on buying them if I can make do without. And, most of the time I can.
There is one item, however, that I cannot find an alternative for and that I keep buying and buying.
(note to any home-builder: Never, ever, ever put white trim in your home if you plan on having children. Oh boy!)
Basically, our walls and trim and doors always look filthy, and these sponges work like...you guessed it...Magic! I also use them to scrape soap scum off the bathtub, and yesterday they successfully removed oil-based paint from wallpaper.
So, while you may see me making-do with baking soda and vinegar, these I cannot do without.
