I don't know about heat and Roundup, but you could try bleach now instead. Roundup is an agent orange derivative, so regardless of what it says on the label, be careful if you are using it in a place where kids/pets will be or where you might be growing food. Not that bleach is totally harmless, but it's half-life is much shorter than Roundup (according to the chemistry majors in my family).Quote:
