How to remove scuffs from glass mirror

My wobbly coat rack fell and scuffed my mirror AGAIN.

Get a blob of peanut butter on your paper towel.

Place on mirror and rub in well. Remove excess peanut butter with a clean paper towel.

Get your glass cleaner of choice and clean mirror.

YAY! No more scuff mark! It's hard to get the mirror without the glare from the window!

I was inspired by a Snapguide someone did to remove scuffs from their chrome bumper. I can not find that guide, but thank you. This trick has saved my mirror MANY times now.

Anyone know how to fix a wobbly spinning coat rack?
