So you scored a sweet little brass antique for a song at the flea market. Only problem is…God only knows what kind of dirt is crusted on that thing. Rather than running around town trying to find just the right cleaner, all you need to do is open your fridge--and pull out some yogurt.
What you need: Your tarnished brass piece, plain yogurt, one damp rag, two clean rags and a sink.
Step 1: Take the damp rag and wipe down the item.
Step 2: Dip a clean rag into the yogurt and get to rubbing. Basically go to town until your bowl, candlesticks, lamp, whatever is shiny and new.
Step 3: Take the second clean rag and wipe off any excess dairy. Wash the piece with hot soapy water, and then buff it dry.
Why it works: The yogurt's lactic acid eats away at tarnish and brings your brass back to its former glory.
