I have a small throw rug I accidentally spilled a whole container full of cinnamon on.
It's now quite brown -- I simply threw it in the wash, and thought that would take care of it -- not noticing it hadn't, it went in the dryer after.
Well, I've tried vinegar, baking soda, and peroxide so far, and it's still quite blotchily brown.
Any suggestions for trying to save it?
