High-Rise Window Cleaning : Cleaning High-Rise Windows: Treating Hard Water Spots With Acid

[slntsteve]

it sounds like you know your stuff, but when does hydrofluric acid never need protective gloves, goggles, respirator? that is some dangerous stuff. I see no safety steps in the video, that sends the wrong message and some schmuck might think that he can do that and spill that stuff on his hands and then its to the hospital with acid burns! other than that great vid! im picking up some cc550 right now! thats all i could find at my local hardware store that said is made for hardwater.
