    FWIW I concur, and yes I have personally used HF based reagents in both semicon & metal finishing environments. It was only just worth the trouble in a professional, "I was getting paid for it and had a full rubber suit etc etc and a safety drench shower and gluconate first aid kit and panic buton within reach" environment.
    Also FWIW it's weak acid not a strong, acid using those terms in the chemical jargon not colloquial sense. But that isn't important to the OP's practical application, HF is unusually hazardous.
