I just ran across this old video on You Tube. This clip was taken from the film, More Dangerous Than Dynamite, produced and directed by the California State Fire Marshall in the 1930s. Early dry cleaners used petroleum-based solvents, such as gasoline and kerosene. The use of highly flammable petroleum solvents caused many fires and explosions, resulting in government regulation of dry cleaners. Thank you markdcatlin
for this great You Tube video.
