Hi all just wondering if there is anyone out there that knows where to get super washing soda. Not to be confused with baking soda. I'm trying to make my own laundry soap and this item has been very hard to come buy locally. Tried SS on main and up at Trinity also home hardware and home depot. I am at a lose and am close to giving in and going online to buy this. Anyone know where abouts a girl can get some washing soda.
