Fixit: Rent metal detector to solve ring case

Q I lost a ring with great sentimental value at a beach. Could it be found with a metal detector? How do I find one, or somebody to search the sand for my ring?

A You can rent metal detectors. Check yellow-page directories for metal detector retailers.

Tom Myhre of Metal Detectors in Minneapolis said that there's a fairly short learning curve to using them so you can do it yourself. He rents units that can be used in water for $39.95 for 24 hours, and land units for $29.95 for 24 hours.

If you want somebody to search for you, Myhre suggests you call him at 612-721-1901 with details of where you lost the item and he will try to find a person to search for you.

Unloading unwanted mirrors

Q How do I get rid of some big, old mirrors?

A You can list the mirrors at www.twincitiesfreemarket.org. This is a local site for people interested in getting rid of stuff or getting stuff for free.

If the mirrors are broken, consider donating them or using them yourself for craft projects. If not, throw them away. Check with your garbage hauler for details. In Minneapolis, for example, they ask that small pieces be double bagged and placed inside the cart. Place larger pieces next to the garbage cart. Please post a sign or write on the item "Please take."

Also, to trim broken mirrors into smaller mirrors, contact a glass dealer.

Cigarette stains on concrete

Q People who smoke outside my building put out cigarettes on the walks and steps. Even after the cigarettes have washed away, a stain remains on the concrete. How can this be removed?

A Try applying a solution of washing soda (Arm & Hammer is one brand) and water. Let it stand for several minutes, then scrub with a brush. Rinse with clear water and allow to dry. Once the concrete is cleaned, you might consider applying concrete sealer. Sealed concrete is less likely to stain and is easier to clean.
