They are chelators.. just not as strong if I understand correctly. I have mixed feelings about using chemicals vs. natural. I prefer natural. But haven't used those other than in salsa here and there : ) Andy warned me off it but I don't have personal experience. His methods make sense to me, but at the same time I'm not comfortable using them.

And I personally do NOT have money to burn....wish I did. Even when I was a 20 something I used my money more for herbs, etc., than clothes. Now I'm afraid I'm more into clothes : )
