Maintenance

Reaming

After a pipe has been smoked for a long time its cake may become so thick that it significantly reduces the capacity of the bowl. In very extreme cases, an overly thick cake may actually crack the bowl due to differential expansion. Ideally, the cake should not exceed one-sixteenth of an inch (about 1.5 mm) or so. When the cake exceeds this thickness, it should be carefully reamed. Some pipe tools have a blunt-pointed (to prevent gouging of the bowl bottom) knife blade for this purpose. While these will work, it is very easy to trim the cake unevenly or even inadvertently dig into bare wood. Numerous adjustable, multibladed reamers are available commercially, and these will do a much neater job. A favored tool for this task--suggested by pipe maker extraordinaire JT Cooke--is nothing more than a series of short wooden dowels of varying diameters that are wrapped with fine grit emery cloth or sandpaper. Whatever device you choose to use, work very slowly and carefully to prevent damage to your pipe. The idea is to gradually shave the cake down to the proper thickness, not to scrape it out in chunks. If you have more than the usual number of thumbs, you might want to take the pipe to your tobacconist, who will usually perform this task for a nominal fee.

What can I do when my pipe "turns sour"?

A pipe, properly cared for, will probably outlast its owner. Occasionally, however, a pipe may begin to taste bitter or "sour." Sometimes this is caused by not allowing the pipe sufficient time to "rest" between smokes; other times, no cause can be determined with certainty. In any event, such a pipe can usually be rejuvenated by applying the "Professor's Pipe-Sweetening Treatment," publicized by Dennis Congos.

First, find some salt (non-iodized is preferred, but not essential), some alcohol (preferably "Everclear," or some other form of near-pure, non-denatured ethanol), and a place to rest your pipe in a semi-upright position. Insert a pipe cleaner into the stem of the pipe so that it extends into the shank. Fill the bowl to the rim with salt and drip or carefully pour alcohol into the bowl until the salt is just saturated. Try not to get any alcohol on the pipe's exterior, as this may damage the finish; any spills should be wiped up immediately. Leave the pipe alone for a day or two. After this time the salt will have turned brown from the absorption of "tars" from the bowl. Thoroughly clean all salt from the bowl and set the pipe aside overnight to dry completely. Your pipe will now be revitalized, and all traces of bitterness should be gone.

WARNING: Many people swear by this process, but the procedure is not risk-free. Some people have had pipes crack after this treatment, particularly when they allowed the salt and alcohol mixture to enter the pipe's shank and/or when they left the mixture in the pipe for several days. Any pipe with significant monetary or sentimental value should be sent to a professional pipe repair person.

Polishing stems

Vulcanite stems can oxidize, turning a disgusting brownish green color. This is one case where "an ounce of prevention" definitely pays off. Avoid exposing vulcanite stems to direct sunlight whenever possible, and wipe off your stems after each use. When oxidation does begin to form, it can often be removed with a mild abrasive, such as baking soda or toothpaste. If the oxidation is too severe for this treatment, jeweler's rouge or an automobile rubbing compound will often do the trick. For truly stubborn stems more drastic measures may be required. An overnight soak in household bleach will turn your stems black again, but you should be careful to cover any stem logos with a blob of petroleum jelly to protect them prior to soaking, and you should be prepared to apply some elbow grease to polish the stem surface, which will be roughened by this treatment.

Professionals (and "serious amateurs") remove oxidation with a buffing wheel loaded with Tripoli or some similar abrasive and then apply carnuba wax to protect the stem and bring out a high shine. If you wish to use a buffing rig, consult with someone experienced in such matters. It's all too easy to burn a stem on a buffing wheel running at excessively high speed or, for that matter, to catapult a briar into your face.
