Also talk to your pharmacist - you'd be surprised what they can order, you may be able to get some acetic acid that's a little more potent than kitchen vinegar there. (either to use straight or dilute for less $ than kitchen stuff) You could also concentrate your own, since the boiling point of acetic acid is ~118°C, vs 100°C for water., so the water will evaporate before the acetic acid. (but stick around 50 and do it slow, or your house will still stink like vinegar!)
