Ok so it gone like this :
Me : I red on some forums that I could save a lot of money by switching from PBW to Oxyclean Free. Do you want to go to Walmart tonight?
Him : You mean the cloth cleaner? Hum, there's no way it's food grade.
Me : I don't think PBW is neither.
Him : Well, I don't think you're right. Like dish soap, PBW must be somewhat similar in terms of food regulation. And I don't find the full chemistry compounds of Oxyclean. Also, it's a really strong stuff, it may detach some micro particles of plastic off your bucket.
So I'm asking you guys.. is it safe or not? Should I play safe and buy that expensive pbw?
