A few days ago, I was exploring a grocery store I hadn't been to yet, and while I was disappointed by the selection they had, I found this little jewel! Baking soda. In a shaker. For cleaning. And I checked: it's refillable (it only cost just over a dollar, but still, baking soda is a lot cheaper than that).
I have been using baking soda a lot for cleaning lately, and I had been wishing for something exactly like this. Hooray!
