for real.. glacial acetic acid is some strong stuff!

Yeah, 100% acetic acid should be treated with care! I think it's about the first lesson in a chemistry class that you never ever sniff directly at the opening of any bottle but only use your hand to fan some odor towards your nose (after making sure it's not something poisonous to begin with).

AFAIK, you usually can buy 10% acetic acid at drugstores which is a much more convenient concentration to use as a stock. As Bill already mentioned, do dilute it further for actual use. I find about 1% pretty good for cleaning purposes (kitchen vinegar has about 4% - so 1% is very safe).
