What are the right questions to ask regarding additives?
I would really want to know the % of sodium hypochlorate. I would really be surprised if it isn't listed somewhere on the bottle, maybe not very clearly. Some grocery store generic brand bleach around here (Ottawa, Ontario) have 3.5% content and aren't cheaper than the Javex with 5.25%. I don't know if that nasty bit of marketing is in the US or not but I would be wary of a good price without knowing the strength of the product.
