Pipe Cleaning and Maintenance

Pipe cleaning and maintenance is the set of habits that keeps a pipe tasting clean and lasting long. In practice it's handled in three stages: a quick clean after every smoke, a regular cleaning done at set intervals, and a deep clean applied when needed. It's hard to give a fixed schedule for frequency; it's accepted that this should be adjusted to how much you smoke. The golden rule of maintenance, though, should be known from the start: the mouthpiece (stem) is never removed while the pipe is hot. Since the shank expands when warm, forcing the connection while hot can crack the briar body; the parts should only ever be separated once the pipe has cooled completely.

After Every Smoke

Once the smoke is finished, the ash and any unburned tobacco left at the bottom (dottle) are emptied from the bowl. Since knocking the bowl against a hard surface can damage the body, using a cork-lined ashtray or the palm of the hand is recommended. While the pipe is still warm, a pipe cleaner is run through the mouthpiece to remove moisture from the airway, and the rim is wiped with a soft cloth. This short routine slows tar buildup and delays souring. Resting the pipe between smokes is also considered part of maintenance; this is covered in the pipe rotation and resting entry.

Regular Cleaning

At set intervals — potentially weekly with heavy use — a more thorough cleaning is done. A bristled pipe cleaner soaked in high-proof drinking alcohol is run through the mouthpiece and shank; the mortise is wiped with a cotton swab dipped in alcohol; then the parts are dried off with dry cleaners. Neutral alcohols are preferred so as not to leave a taste; spirits such as rum or whiskey will leave a flavor in the pipe. Opinions are split on isopropyl alcohol; out of concern for residue in the part that touches the mouth, many smokers stick to drinking-grade ethanol only. Harsh alcohol should not be allowed to touch the finished outer surface. Checking and controlling the thickness of the sooty protective layer in the bowl is also part of regular maintenance; details are in the carbon cake and reaming entry.

Deep Cleaning: The Salt-and-Alcohol Method

A narrowing draw, a sour and burnt taste (what's called a "sour pipe"), and increasing moisture by the end of a smoke are considered signs that deep cleaning is due. The classic method is the salt-and-alcohol treatment: with the mouthpiece removed, the bowl is filled with iodine-free coarse salt, the salt is moistened with alcohol, and the pipe is usually left standing upright for 12-24 hours. The alcohol dissolves the tar, and the salt absorbs what dissolves; at the end of the period, the salt is discarded, the bowl is cleaned, and alcohol-soaked cleaners are run through the airway. The method isn't without risk: cracking has been reported in cases where the mixture seeped into the shank or the treatment was left on for days; it's recommended the pipe be left to dry for at least a day afterward. There's also a variation using cotton instead of salt; which is superior is debated. The lingering scent left by aromatic tobaccos can only be reduced through deep cleaning; this is covered in the ghosting entry.

Differences by Material

• Mouthpiece: vulcanite (ebonite) mouthpieces oxidize and dull over time and need regular wiping; acrylic (lucite) mouthpieces don't oxidize but are harder. See the mouthpiece materials entry for details.

• Meerschaum: the body is more sensitive to alcohol and water than briar; a carbon cake isn't wanted in the bowl either. Cleaning is done mainly with dry cleaners, taking care to preserve the wax coating on the outer surface.
