I remember looking at the porcelain kitchen sink the day we moved into our home and making this mental note: Must replace sink right away. The problem? The previous owner was a bleach freak, a habit that removed the shiny finish and left the sink dull and susceptible to staining. Not long after, I found a friend — one who showed me how to remove all stains. As long as it was very white, that finish issue wasn't a problem. It's been 21 years, and my friend and I still are keeping that same sink looking nearly like new. Curious? Read on. …

RUSTY SINK. Here's a great way to get those ugly rust stains out of your porcelain sinks: Use Bar Keepers Friend, a cleaning product available in many supermarkets. Just sprinkle a bit on a wet sponge, and get to work scrubbing. The rust stains will come off like a charm. Just make sure you do a test in a small space first. — Bill, Michigan

SPOT THE STAIN. Before my family members put a spotted item of clothing in the hamper, they tie the arms of the shirt or the legs of the pants together. That's the sign that tells me I need to treat spots on that garment before washing. — Karen, e-mail

NO-STICK CAKES. I have found that if I grease my cake pans with butter first and then pop them in the refrigerator while I am mixing up the batter, the cake never sticks to the pans once I pour in the batter and bake it. Give it a try! — Bethany R., Ohio

SLOW DOWN THE DRESSING. When you open a new bottle of salad dressing, instead of ripping off the protective seal, poke a few holes in it with a toothpick. It will be a lot easier to control the flow of dressing. — Tom W., South Carolina

POTLUCK RECEPTION. I've got a great idea for an inexpensive wedding reception: Make it a potluck. Our friends were delighted to be part of our wedding in a more involved way than being merely spectators. They also outdid themselves in what they brought; their favorite or signature pieces filled the table. — Miriam K., e-mail
