I would imagine you'd need more than the standard little box of Arm and Hammer that you put in your fridge...
I used maybe two of the small boxes that you are referring to.
Where do you buy huge quantities of baking soda?
You could probably get a tub of it at a good grocery store or a Sam's Club.
Also - is it safe to just let it run into the street drains? What do you do with all the baking soda that goes everywhere?
Baking soda is non hazardous to your health. After all it is used in some baking recipes and you eat it. As far as the mess just hose it down and you're done. It dissolves right away.
