please read the label closely. some manufacturers of brake clean solvents list on their MSDS the reactivity with fire to create phosgene gas. this is a horrible inhales poison and there is no cure for poisoning resulting from this gas. if caught soon Systemic damage to the lungs can be prevented. if you cannot find the information on the label contact the manufacturer, if they don't respond quick enough with the holidays I would get my *** into an emergency room quickly. I'm not trying to scare you this is just a horrible fact.
