Been using Ace brand naptha for a while its been totally consistant just bought some that smells totally different. It smells like a different solvent it has an ammonia-like odor to it that seems to remain after evaporation . I also had a batch of spice come out a greenish color for the first time ever.
is it posssible that this naptha is bad or they put something else in it?
