The ingredient in chlorinated brake cleaner that will react and create toxic phosgene gas is tetrachloroethylene.
I know a lot of people use white lithium grease to lube their tube benders as the tubing slides through. I am concerned after reading the liquid wrench msds.
I was shocked to see the main ingredient in Liquid Wrench White Lithium Grease is... tetrachloroethylene.
Why in this link for the exact same lithium grease is tetrachloethylene no where listed?
The warnings about brake cleaner have been widely posted but this is the same exact chemical hidden in white lithium grease. For years I have welded on tubing that had lithium grease on it and I am sure many people have too as it is such a commonly used lube for tube bending.
