Congratulations on your new student-level flute, oboe, clarinet, bassoon, or saxophone! Your music store’s friendly sales associate (or your online retailer’s auto-suggest software) is probably insisting that you purchase a “care kit” as well. This kit ostensibly contains all the items you need to keep your new instrument working well and looking shiny. I recommend that you do not buy it, because it is, at best, a waste of your money, and, at worst, a hazard to the instrument’s wellbeing.

Here are some of the items that frequently appear in these terrible kits:

• Polishing cloths. Chemicals or polishes (liquid or embedded in cloths) can gum up pads and mechanisms. Students can “polish” their instruments with a soft, dry cloth, like a piece of an old t-shirt. Your repairperson can remove the keys and do a more thorough polishing safely.
• Swabs. Woodwind instruments should definitely have swabs, but beware the kinds in these kits.
  Silk is preferable for pull-through swabs (oboe, clarinet, bassoon, saxophone) because it is absorbent and compressible, so it’s less likely to get stuck inside the instrument than a cheaper felt swab. Even for a student instrument, it’s worth a few extra dollars to get silk.

  

  For flutes, avoid “headjoint swabs” that are little oddly-shaped pieces of chamois (or a synthetic version), unless you want to have to fish them out of the headjoint every time you try to use them. Instead, use the cleaning rod that came with the flute, plus a strip of fabric cut from an old bed sheet.
  The fuzzy “cleaning” brushes that look like giant pipe cleaners, that you insert and leave inside the instrument, do exactly the wrong thing by keeping all the moisture inside the instrument, instead of wiping it out like a good swab does.

• Cork grease. Yes, for instruments with parts that friction-fit together with cork, such as clarinets, oboes, and saxophones. Flutes don’t have any corked joints (though some piccolos do). Some bassoons have corked fittings, but some have thread wrappings instead. Use cork grease on cork only—never on thread-wrapped or metal-to-metal joints.
• Screwdrivers. Yikes! Woodwind instruments often have “adjustment” screws. Bored students and well-meaning dads can’t resist just tightening everything up, just to make sure. This leaves the instrument in unplayable condition, and only a professional can put those adjustment screws back just right.
• Reed guards/cases. Yes! Keeping reeds in one of these generally keeps them intact and in playing condition for longer than the disposable ones that the reeds come in. Those little plastic or cardboard sleeves that clarinet and saxophone reeds come in don’t keep them flat when they dry. And oboe and bassoon reeds often come in tubes that are too flimsy for regular use, or hinged plastic cases that come apart in the instrument’s case, leaving the reeds to bounce around unprotected.
• Mouthpiece brushes. These are basically little vegetable brushes, with scratchy synthetic bristles and the dreaded twisted-wire core, much too aggressive for cleaning clarinet and saxophone mouthpieces. Instead, try a gentle rinse with room-temperature water and a drop of mild dish detergent. Stephen Howard’s vinegar-and-cotton method is good for occasional deeper cleanings.
• Neck or bocal brushes. Probably too aggressive for use on these particularly delicate and crucial instrument parts. Plus, a strong risk of getting something stuck.
• “Tone hole cleaners.” These are usually garden-variety pipe cleaners. Tone hole cleaning isn’t a task for beginners to do. The pipe cleaners’ twisted-wire cores can damage toneholes, the instrument’s bore, or pads.
• “Pad papers.” It’s really tempting to use a lot of pressure with these, which can distort pads and cause leaks. Some are coated with a powder—these operate on the same principle as getting some gum stuck on your shoe, then stepping in some dirt so the gum won’t keep sticking to the sidewalk when you walk.Pad papers and other powder treatments should be an emergency treatment applied wisely and carefully by a knowledgeable musician, not a daily treatment applied badly by a student.
• Key-dusting brushes. Gently removing some dust from the instrument’s mechanism isn’t an all-bad idea, but be advised that it’s easy to knock springs and things out of place. The brushes in these kits usually have twisted-wire cores, which can scratch instruments’ finishes. Instead, consider using cheap kids’ watercolor paintbrushes. Or, even better, make sure the instrument gets professional maintenance and cleaning at least once a year.
• Key oil. No, no, no. This is a job for a professional to do. Besides, the kind in these care kits is usually cheap 3-in-1-type oil. Even if applied properly, it tends to drip back out of the keywork onto fingers, or worse, pads.
• Bore oil. Absolutely not. Using this at all (only in wooden instruments) is controversial. When you bring it in for its annual maintenance, your repairperson can apply bore oil properly and safely if they deem it necessary. (My opinion: if in doubt, don’t bother.)
• Care manuals. These are generally provided to justify the other items in the care kit.

Skip the care kit—they are a way for retailers to squeeze a few more dollars out of you at purchase, and then more when you bring the instrument back in to fix the damage you have done with your brushes and oils and screwdrivers.
