So, the carpets looked pretty good when Coyote was done. Now I don't have to explain what the biohazard spot is to the landlord (because Coyote got it out!) And thankfully, we managed to make it out of the apartment before anyone managed to spew (unfortunately for our new place. We have been here 3 weeks and already have reached superfund status with the EPA).
The tech was personable, but kept talking about some acid that every stain had in it that would prevent him from getting the stain out. Every stain, no matter the source, had it, and it sort of sounded like bunk. But really, who cares if they get the carpet clean? And so, the carpets are clean and everyone is happy. All is right with the world.
