Do you SEE any issues after cleaning it off? If not, you should be OK. If there is still some residue, or it wrecked your paint, I hope you took pictures for evidence. Then you could show the apt mgt, and have them contact the lawn care folks and make them pay for anything that needs to be done to remove it, like a pro.

 

I didn’t see anything wrong after cleaning it off so I suppose that’s good. I definitely should have taken pictures though.

 

I’d think you’re fine, next time take pictures and tell the manager what occurred and to let the contractor know to be more careful. Knowing the epa and their rules it has to be something that doesn’t damage anything except what’s it stated purpose is.

 

I doubt there'd be any permanent damage done in that short of a time period, particularly where it's ceramic coated and you rinsed it off shortly afterwards. It could have been a solution of fertilizer, herbicide, or insecticide. You should find out what was actually sprayed and mention it to whoever hired the service provider to let them know NOT to let it happen again!

 

If nothing is there after you cleaned it you’re good.
