Basic Furniture Refinishing

QUESTION: I have a 1930's silky oak drop-door desk that has been in our shed for about 20 years.
It has seen a few cyclones and had a lot of weathering and the doors are off and knobs missing.
This desk holds special memories for me as a young child watching my dad working at it. I’d like to refinish it but have no idea where to begin. How hard would it be for a beginner like me to refinish it?

ANSWER: Your desk sounds like the ideal piece of furniture on which to learn about refinishing furniture. For many beginners, refinishing seems easy, but it’s far from it. First you need to decide if the piece needs to be completely refinished or the original finish preserved. Your desk sounds like it may fall somewhere in between.



It’s only been within the last 20 years or so that refinishing products have appeared that make the job less intimidating. However, most people think you have to strip off all the old finish before applying a new one. That all depends on the condition of the piece.

You piece sounds like it’s been through some tough times. Before you do anything, you need to evaluate it. Has the finish been mostly removed by weathering or is it spotty. If it’s the former, then you’ll need to sand it following the grain of the wood with fine to medium grade sandpaper. If it’s the latter, you may be able to just clean it up and apply a new coat of varnish. With refinishing, a little effort goes a long way. The nearer you can keep your desk to its original condition, the better.

Let’s assume the worst. If the finish has mostly been removed by weathering, you’ll need to remove what remains with a good varnish remover. Be sure to buy one that’s water soluble. Even though this takes longer to achieve the results you want, the fumes are mild and cleanup is easy. When using a remover, always brush it on with the grain of the wood. Do a little section at a time, turning the piece on end if necessary to make it easier to apply the remover. Scrap it off with a putty knife, and be sure to have a roll of paper towels handy to wipe up the excess and stripped varnish or paint.

After you’ve completely stripped your desk of its finish, lightly sand it with fine sandpaper. Wrap the sandpaper around a wooden block for support and sand with the wood grain. Be careful not to over sand----just enough to smooth the surface. After you’re finished sanding, wipe the desk with a damp cloth to remove all the dust. Do not get the wood wet.

Once you have prepared your desk for its new finish, let it rest for a day to make sure the surface is thoroughly dry. Dust it off with a dry cloth to make sure it’s clean, then begin to brush on a new finish using a soft-bristle brush and a furniture finish called tung or Chinese oil. Several manufacturers make this, including Formbys, and you should be able to buy it at your local hardware or home center. Apply the tung oil or a piece of white tube sock or other soft cotton material going with the grain of the wood.. The first coat will soak into the newly stripped wood. Let it dry 24 hours, then sand lightly with fine sandpaper. Dust it with a damp cloth again and let dry. Apply a second coat of the tung oil and repeat the process, except this time rub it with 0000 steel wool after it dries. Dust off again and apply a third and final coat of tung oil, but don’t rub with the steel wool this time.



The advantage to using tung oil is its rapid drying capability. Though it will feel dry to the touch in an hour or so, be sure to let it thoroughly dry for 24 hours. And don’t apply it on a humid or rainy day. And here's a tip: Wrap your application cloth in plastic wrap or put it into a Zip-Loc sandwich bag and place it in your freezer. Take it out 30 minutes before you're ready to apply another coat, and it will be ready for you.

Be sure to tune in next week to learn about preserving the finish of a piece of furniture that isn’t in such bad shape.

Leftovers from the Medicine Show




QUESTION: I have  a collection of old medicine bottles, all unopened, that I from an old local pharmacy that I bought at auction. Most contain narcotics and have the original corks intact in them.  How should I dispose of the contents, mostly liquid, some pills, how to remove the corks to save them, as well as how to clean the bottles without ruining the labels?

ANSWER: Old medicine bottles can contain some nasty substances. Many are extremely volatile and shouldn’t be mixed with any other substance. But before I get to disposing of the contents, it’s important to know what the laws are governing them.

Collectors of old medicine bottles do so for the bottles, themselves, if made before 1920. They’re especially interested in the bottle shapes. Those who collect bottles made after 1920 collect them for their contents and their labels. Generally, while collectibles, like cereal boxes, are worth more with their contents unopened, this isn’t so with old medicine bottles.


   
Laws governing the sale of containers with flammable, corrosive or poisonous contents have been on the books since 1908.  Cough syrups and other medicines often contain alcohol, classified as a flammable liquid by the Food and Drug Administration (FDA). The penalties are severe for selling bottles containing dangerous substances, especially in today’s terrorist-prone world.

Nationally, it’s the responsibilities of the Drug Enforcement Agency (DEA) to regulate toxic substances and investigate violations. In 1970, Congress passed the Controlled Substances Act, Title II of the Comprehensive Drug Abuse Prevention and Control Act, which became the legal foundation of the government's fight against the abuse of drugs and other substances.

The law is a bit lax when it comes to poisons, such as strychnine and a deadly product called mercury bi-chloride, formerly used as an anti-syphilitic and to clean wounds. So how do you dispose of nasty substances like this?

While most drugs can be thrown in the household trash, you need to take certain precautions before tossing them out, according to the FDA. The agency used to recommend that people flush some drugs down the toilet, but they no longer do since some of these dangerous substances have been found in the soil and water table. One possibility is to pour kitty litter into a plastic bucket and then pour the bottle contents—cough syrups and other liquids—into it. Let it sit for a while, then scoop up the kitty litter into a double plastic bag and toss it into your trash. Make sure you use enough kitty litter to soak up the contents. Do this outside preferably on the day before your trash will be collected.



You can do the same with pills and capsules, but instead of kitty litter, use coffee grounds. Pour the capsules in a Zip-Loc plastic storage bag containing the coffee grounds and mix the pills into them. Seal and place in your trash.

If you’re not sure how dangerous your bottle’s contents might be, you can look up the medicine in an older edition of the Physician’s Desk Reference or the Merck Manual. However, some of these substances, such as mercury bi-chloride, may no longer be used and, therefore, won’t be listed in any of the reference books. If in doubt, check with a local pharmacist.

The easiest way to clean old medicine bottles after you have disposed of the contents is to rinse them with a solution of warm soapy water. Don’t make the water too warm or the label will come loose. If the bottle has any residue or stains in it, especially those with narrow necks and small openings, you can buy a set of inexpensive fish cleaning brushes from your local pet store. If you can’t find these, check the baby aisle in your local drug store for soft bristle baby bottle brushes. If the stain persists, pour a 50/50 solution of white vinegar and water and let it set for a few hours, then try brushing the inside of the bottle again.

Unfortunately, the corks on old medicine bottles will have absorbed some of the solution and are just as dangerous as the bottle’s original contents, so throw them out. However, you can reuse those on bottles containing pills.

An Ounce of Prevention is Worth a Pound of Cure



QUESTION: What’s the best way to maintain antique furniture? When I see pieces at antique shows, they always look so beautiful. Is there some trick to making them look that way? Can you tell me the best way to maintain the pieces I have? While I have some older ones from the early 19th century, most are from the mid to late 19th century.

ANSWER: You’ve asked about two different procedures. The first is all about restoration while the second is about conservation.

Generally, restoring pieces made before 1830 affects their value. If a piece is more than 60 percent restored, it drastically loses value. Refinishing these early pieces destroys their patina. On the other hand, pieces made after 1830 usually benefit from restoration. The 60-percent rule doesn’t apply to them.




Restoration can range from minor repairs to a complete professional refinishing. With improvements in materials and finishes, a person can do some simple refinishing at home. However, for more complex work, especially when a piece may have several layers of old paint that have to be removed, it’s a good idea to invest in the work of a professional furniture restorer.

Before attempting to refinish a piece of antique furniture, assess it’s overall condition. If the piece just looks dull and dingy, it’s possible it may just need a thorough cleaning. Cleaning wood can do wonders for it.

If there’s oily dirt or grease, such as may get on pieces in a kitchen, remove it with an old washcloth, soaked in a mild dish detergent and water solution and wrung out. Work on small area at a time and dry it immediately with a soft cloth. Always avoid using too much liquid directly on a piece’s surface.

An alternative is to use Murphy’s Oil Soap in spray form. Spray a little on the wood and wipe with a damp washcloth. For really grimy surfaces, use #0000 steel wool and Murphy’s, then wipe with a wet washcloth, and dry. Allow the piece to dry thoroughly for 24 hours before waxing. Wipe the surface with #0000 fine steel wool until smooth.

After a piece of furniture is cleaned, it can be freshened up using Wood Sheen, a rubbing oil stain and finish made by Minwax that combines tung oil with a coloring agent, available at most hardware stores and home centers. This product comes in a variety of wood stain colors to match most types of wood.  tra fine (four zero) steel wool. Wipe the surface again with a damp cloth. Apply a thin coat of Wood Sheen using an old sock and let it dry for an hour or two. Do not do this more than once every year or so.

An alternative to using Wood Sheen is to wax it with Minwax paste wax. This is a petroleum-based product that comes in both natural and dark shades for light and dark-stained furniture, respectively. The hard surface it produces can be dusted more easily and without the danger of scratching because its smoother. Waxing once or twice a year is sufficient for table tops and chair arms. For less used areas of furniture, such as chair legs and case pieces, wax only every four years.

Conservation of antique furniture is all about maintenance and keeping it clean. Avoid using any of the popular spray dusting helpers. These tend to leave a nasty buildup on furniture that’s hard to remove later on. Instead, use a soft cloth to gently wipe away the dust. You can also slightly dampen the cloth with liquid glass cleaner.

Avoid using any of the popular oil-based liquid furniture polishers. These leave an oily residue that attracts dust. Lemon oil is one of the worst because it doesn’t sink into the wood like commonly thought but lays on the surface acting as a dust magnet.

Be extra careful when cleaning any wood that has been gilded. The gilt is usually applied with a water-soluble adhesive which can be removed by detergent cleaners. To clean uneven or carved surfaces, use a soft-bristled brush or your vacuum cleaner with the brush attachment. Be careful not to hit the furniture in any way with the vacuum cleaner, itself.

Do not use feather dusters. They move the dust around and can scratch the surface.

Before using any cleaner on a piece’s surface, test an inconspicuous area towards the back first.

Try not to polish hardware while it’s attached to the furniture. The polish will damage the furniture’s finish. Instead, remove the hardware and polish separately, being sure to rinse or wipe it thoroughly before reattaching it to your pieces. If hardware cannot be removed, be sure to mask it from the furniture’s surface to prevent damage. For ornate hardware, use a cotton swab dipped in the detergent solution.

Do not polish ormolu, which really isn’t brass but bronze. Instead, wash it with a soft cloth soaked with a mild dish detergent.

If mold or mildew forms on a piece of antique furniture, dampen a soft cloth with a very mild bleach solution (two tablespoons of bleach to a quart of water) and wipe the affected area. Dry immediately with a soft cloth, then wax as stated above.

Heat dries out the wood of antique furniture, loosening joints. An interior should be kept at a comfortable level but not excessively hot in the winter. If the temperature must be kept higher, put pans of water around to humidify the air or use a humidifier. The air will be healthier, also.

Whistle While You Wax



QUESTION: I have quite a few old pieces of furniture, some of which are antiques. I’m never sure what to use to clean and polish them. Can you offer any advice?

ANSWER: You’re not alone. Many people don’t know what type of cleaners and polishers are appropriate for antiques and end up using the wrong thing.

Before you can figure out what type of cleaner and polisher to use on your furniture, you first have to know what sort of finish the maker used on it. The most common finishes found on antique furniture are waxes, oils, shellacs, and varnishes. Not only do these finishes bring out the beauty of the wood's grain and color, but they also protect the wood from moisture and heat changes that can cause shrinking, swelling, crazing, and cracking. Finishes seal the wood pores against dirt and grime, too.

But over the years, wooden furniture dries out and shrinks or expands or warps from too much moisture. Older antiques sat in rooms heated only by a fireplace. If they sat too close to the fire, they dried out—too far away from it, they tended to warp.

In order for a finish to protect the wood, you have to protect the finish. This can be done by cleaning and polishing the finish with either a wax or an oil.

Cleaning furniture is a simple process. Using a solution of Murphy’s Oil Soap or the spray version of it, apply some to a well-wrung-out old washcloth. Rub a small area of the piece at a time and immediately dry it with either paper towels or an old towel. If the piece is particularly grimy, you may have to wash it several times. Be sure not to get the wood too wet and dry each area immediately. After you finish cleaning, let the piece dry thoroughly for 24 hours. For a really bad piece, you can also use one of those green scrubby squares. But don’t rub too hard because you may rub off the finish.

Once your piece is dry, it’s time to apply a new protective coating. The preferred method of protection is a wax since they’re easy to apply and leave a brilliant shine. The best waxes to use are those in paste form. Stay away from Pledge or other so-called spray cleaners and waxes. They apply a film to the surface of furniture which attracts dust like a magnet. Instead, look for products that contain Carnuba wax, a natural substance from a palm tree native to Brazil that’s durable and produces a glossy shine when rubbed vigorously.

Another reliable polish is beeswax, which has been around for many years. A variety of paste and liquid polishes containing beeswax are available.

Minwax Paste Wax, made from petroleum products, is a third alternative. It produces a durable hard shine that lasts up to a year. The more coats you apply, the more waterproof the surface becomes.

Oils such as Tung and linseed have been used for centuries to preserve and polish furniture finishes. They're often mixed with absorption promoters, so they actually sink into the wood pores rather than remaining on top as waxes do. Oils leave a lustrous shine that's softer than a glossy wax shine, and they provide good protection against moisture. However, they do tend to darken the wood slightly over time.

Regardless of which cleaner/polisher you choose—wax, oil, or feeder—always use the same type on a particular piece of furniture. Finish surfaces that are accustomed to one type of cleaner/polisher won't accept another type. For example, an oil applied to a finish that was previously waxed will remain on the wood surface and won't soak in.

How often you need to clean and polish your antiques will depend on a number of variables, such as the type of heating and cooling system in your home, the geographical location, how you use your antiques, and the type of cleaner/polisher you're using.

Generally, you’ll need to apply a paste wax every month or so. To tell if your piece needs another layer of paste wax, buff the old finish with a soft cloth. If this polishing fails to restore shine and smoothness to the finish, it's time for a new coat of wax.

Boil, Boil, Toil and Trouble
