    We have a polyurea machine and any time work is being preformed on the ISO side there are a minimum of 2 people present so mistakes are not made while working around this chemical.
    You took the words right outta my mouth. I used this stuff many years ago (thousands of gallons of it) and as far as I know the only thing recommended for removing any residue is Acetone. Highly flammable and destructive to most plastics. If you can find a solvent that is "plastic friendly" and safe to handle and dispose of I'd use it.

    Except that he said that of the two chemicals, isocyanates were not what he had. Just resin, not ther isocyanate curing compound. So, I'd think that going to the acetone extreeme would be unwarranted, the goldfish test sounds good to me. Unless you're going to use the containers for keeping $10,000+ show fish.

    Use only totes that have had non toxic substances in them eg food or soap and buy pressure washed usually a small fee. All other tote to the dump

    My tote had a release agent for concrete. I rinsed it out to get the excess out and then I got inside with a scrub brush and hot soapy water and washed and rinsed it two times. that was in late 2008 and was put into use in 2009 and still using it now.
