You are right. Sodium bicarbonate is very slightly abrasive.
I honestly did not think of this one. Odd since I can usualy see the fault in something before I can see an application for it.
However, its abrassivness is slight. Enough so that it is recommended for cleaning glass and other scratch sensitive surfaces in a 50%-50% solution with water. (One random "useful" use for baking soda. Amazing what you can find by scrolling though 30 odd pages of google results.)
About 8g of sodium bicarbonate will dissolve per 100g water at about 20C.
In a two liter system (2L = 2,000g) about 160 grams (5oz - 6oz) would dissolve in water at about 20C. I think that as long as I stay on the conservative side of things there should be no trouble.

It is very hard to get rid of
all the bacteria. But you are right there are much more effective solutions.
But shouldn't it be better than straight distilled water? Or would it not make enough of a difference to be noticable? :shrug:
It is, however, cheap and readily available. What makes it especially attractive to me is it can be thrown out, unlike antifreeze and many other additives.
I think the prospects are intersting enough for me to try it. And suffer any consequences, however, in all likely hood it won't do anything noticeable. In which case I have lost nothing and have gained knowledge. One the other hand if it works well then I have gained knowledge. If it fails miserably, then I will pay the price and gain knowledge.(However, what research I have done suggests that at worst it will do nothing.)
