If your stainless steel sink looks dull and dirty, flour can help you clean it! First, clean the sink with dish soap and water, drain and sides too. Next, dry COMPLETELY. If you don’t, the flour will create a sticky, messy goop!! Worse than you had before! Pour 1/4 cup of flour into the sink and buff using a clean rag or paper towels. For around the faucet, use a clean, old, dry toothbrush. Now, wipe the flour away with a rag, or your Dustbuster, be careful not to let any go down the drain as it may clog your pipes. The flour will have pulled out dirt and grime acting like very fine sandpaper on your stainless steel sink.
