ARM & HAMMER Super Washing Soda Powder Laundry Detergent Booster & Household Cleaner, 55 oz

I got it to make laundry soap. Not the viral one with the "add all these toxic ingredients to make homemade detergent to 'save money' buy spending $100," but the "avoid all the extra toxic and unnecessary ingredients with this four-ingredient laundry soap" recipe I've made for decades. IE: 2c borax, 2c washing soda, 1c baking soda, 1 bar grated nels zaptha (or Castile).

This soda was used to balance my pool water. It works like a charm. The price is much more affordable than other products sold for pool maintenance. It also takes only a few hours to promote proper ph. I wish I had known about this stuff years ago. Instead of wasting so much money on inefficient liquid pool cleaning products.
