Every method below is something people genuinely do, usually with good intentions. Several come from advice that was sound thirty years ago and isn't any more.
Leather is skin. Almost everything on this list makes sense the moment you ask whether you'd do it to your own.
1. The oven
The most damaging thing you can do, and the most popular. Heat makes leather temporarily supple, so it feels like it works. What's actually happening is that the oven is pulling moisture out of the hide. You get a glove that's dry all the way through, with laces that go brittle and start snapping within a season. It cannot be conditioned back.
It's also a genuine fire risk. Leave a glove unattended in an oven and you may have a bigger problem than a ruined glove.
2. The microwave
Same reasoning, worse execution. Microwaves heat unevenly, so parts of the glove cook while others don't. Any metal — eyelets, hardware — makes it dangerous.
3. Leaving it in the car
This is the oven, slower. A car in an Ontario July hits temperatures that dry leather out over an afternoon. In February it's the opposite extreme. Neither is good, and a glove that lives in a trunk year-round gets both.
4. Drowning it in oil
Conditioner is necessary. More conditioner is not better.
Oil softens leather by breaking down its structure. That's the mechanism. Used sparingly it restores flexibility; used heavily it accelerates the breakdown you're trying to prevent. An over-oiled glove goes heavy, mushy, and floppy, and it loses the shape that makes it useful.
A thin coat, rubbed in, a couple of times a season. You can always add more. You can't take it out. That's true of every conditioner on the market, including mine.
5. Shaving cream
This advice was once correct. Older shaving creams contained lanolin, a genuinely good leather conditioner. Modern formulations replaced it with detergents, alcohols and propellants — the chemicals used to foam it and preserve it are actively drying. A generation of players learned this from someone whose coach learned it in 1975, when it worked.
6. Soaking it
Water is the other half of the two things leather can't handle. A soaked glove dries stiff and warped, and if it doesn't dry fully it will grow mould from the inside.
Some professionals do use water methods. It's worth knowing that most professionals get gloves for free and don't need them to last five years.
7. Storing it in the bag
The single most common storage mistake. A bag traps sweat and moisture, holds the glove crushed out of shape, and keeps air off the leather for months.
8. Leaving it flat and empty
A glove with nothing in the pocket relaxes flat — the shape players call a pancake or a taco depending on how it lands. Recovering a pocket that's collapsed over a winter takes real work.
Put a ball in it.
9. Playing on dirt and never brushing it off
Infield dirt is abrasive and it holds moisture. Left in the seams and lace holes, it grinds at the fibres every time the glove opens and closes, and it's a major reason laces wear through at the holes rather than in the middle.
Thirty seconds with a brush after a dusty game is the cheapest maintenance there is.
The short version
| Never | Sparingly | Always |
|---|---|---|
| Oven, microwave, hot car | Conditioner | Brush the dirt off |
| Shaving cream, household oils | Water | Store with a ball in the pocket |
| Soaking | Keep it out of the bag |
