Although its inventor claims that Liqui-Fire is all-natural and is safe to use for thawing frozen pipes, its use is still not supported by health professionals as of 2015. Among the issues against the use of Liqui-Fire include that the material data safety sheet does not list all the ingredients and that it is not certified by the National Sanitation Foundation, according to CBC Canada.
Liqui-Fire is a thick liquid that can be used to eat through ice plugs and applied on pipes to prevent freezing. Canadian inventor David Bobiash found inspiration for inventing Liqui-Fire solution when his pipes froze 25 years ago while he was still living in northern Ontario. While he claims that his product is all-natural, he refuses to divulge all the ingredients in his invention, notes CBC Canada.
