There is a substance in our lawn that is leaving a rusty orange residue on our shoes and if you are barefoot your feet will turn orange. Is this harmfull to humans or pets? I have grandchildren who love to play in the yard but this is very concerning. Can you please help me with this and is anyone else having this problem?
