I have used baking soda and vinegar to clean for ages and it is often difficult to find in large sizes, so imagine how happy I was to see the 12 pounder at Costco for $4.98!
My favorite uses:
1. shampoo. I am trying it again, last year I was seduced by Aveda shampoo after being free for two months. This time I am sticking with it, saves money and plastic.
2. House cleaning. Use practically everywhere, add to wash machine to boost detergent, scrub pans, bathrooms, etc...
3. Bug bites. Make a paste and put it on the irritated area.
Check out here for my ideas.
