EDTA is often added to a cleaning solution(laundry detergent) to help tie up hard water metals and minerals were you to use a detergent without EDTA for laundry in areas that have hard water (iron) clothes would look dirty after the wash

Subject: [DCHAS-L] EDTA in cleanup of aqueous radioisotope solution

I'm teaching a unit on EDTA and its myriad uses in chemistry. I read somewhere about why EDTA is often present in the cleaning solution used to sponge up spills of low-level radioactive aqueous solutions. Two questions:
1) How/why does EDTA enhance the cleanup from a chemical perspective? I'm sure it has to do with the high Kf value for complexation, but I'd love a confirmation.
2) What is done with the contaminated solution after sponging off the area?
