BAKING SODA USES
Baking soda can be used in two ways … in solution, strictly as an emulsifier of grease... and dry, where a scouring as well as an emulsifying action is needed. It's a scratchless scourer, however, that can be used safely on any surface, since baking soda dissolves completely when water hits it. Its other advantage in car care is that it's an antacid which will neutralize the acids that accumulate around batteries and terminals, eating into adjacent metals.
SAL SODA USES
Sal soda concentrated, a stronger alkali than baking soda, is primarily a heavy-duty cleaner. It, too, can be used in two ways … in solution, or dry as a scourer. Since it contains no grit or sediment, and dissolves completely in water, it can't scratch.
