0000 Steel wool and lots of lube would clean the window's without scratching them but this method is a little over the top for just coke. I would stick with some warm soapy water in a spray bottle.

 

Just did a search on "steel wool" and see you guys are taking about a whole different type than what my mother uses to clean her pans.

All the same though, someone turning here for advice could've been very easily mislead with no further details in that post. And my moms steel wool would've definitely sucked.

So, where do you get 0000 steel wool anyway?

 

Any good hardware store will have 0000 steel wool.

 

Walmart has packs of three or four courses in it.

 

No problem.

Just ask questions that's what were here for
