". . . washing soda will consume two equivalents of acid, while baking soda will only consume one equivalent."

Washing Soda is caustic/alkaline with a pH of 11 (with 7 being neutral). Though it does not give off harmful fumes, you do still need to use/wear gloves when handling it directly.Baking Soda is only slightly alkaline with a pH around 8.1 (again, 7 being neutral).
