So we were using our fire grate as a bit of shade near the pool (weird i know) and DP folded it up and sat it to the side.
I was planning on putting this around our x-mas tree so DD can't get in and rip everything off.

Went and got it from outside and it's COVERED in rust, what can i use to clean it off?

Was thinking of maybe using wrapping paper on it but DD would just rip it to shreds and then we possibly wouldn't see most of the tree!

HELP i am putting up my tree tomorrow and don't want DD to ruin it!
