Here's why using Mitt-Spit Break-in accelerates the leather baseball glove break-in process:

Mitt-Spit Break-in is a specially formulated oil that helps to soften and lubricate the leather fibers. This makes the leather more pliable and easier to break in. It has a deep penetrating formula that allows to break in oils be absorbed rapidly. It works best when the leather is warm.
Mitt-Spit Break-in also helps to protect the leather from moisture and dirt, which can damage the glove. The lubricating oils resist moisture from things like dew on the grass.
Mitt-Spit Break-in is easy to apply and use. Simply apply a small amount of oil to a soft cloth and massage it in. A little goes a long way. Because it’s a concentrate, it does add weight to the glove.
Mitt-Spit Break-in will not turn rancid. Many of the glove oils sold these days are prone to rancidity. Not Mitt-Spit Break-in or Mitt-Spit glove oil as the lubrication used has a near zero iodine index. Whereas products made with neatsfoot oil or mink oil have a much higher iodine index.

The break-in chemistry in Mitt-Spit Break-in works by lubricating the internal fiber structure of the leather. This allows the fibers to move more freely, which makes the glove more pliable and easier to break in. The oil also helps to protect the leather from moisture and dirt.

Here are some specific instructions on how to use Mitt-Spit Break-in to accelerate the break-in process of your baseball glove:

Clean your glove with a Mitt-Spit Glove Cleaner. Don’t use soap as soap can damage leather fibers.
Apply a small amount of Mitt-Spit Break-in to the glove. 1/4 ounce should be sufficient for a typical glove.
Massage the oil into the glove. It’s best if the glove is slightly warm. Warm leather will absorb the break in chemistry faster than cold leather.
Let the glove dry completely.
Repeat steps 2-4 if needed. Most gloves only need one application. .

With regular use, Mitt-Spit Glove Oil will help keep your baseball glove leather soft and supple. Your glove will be more comfortable to wear and it will perform better on the field.

Here are some additional tips for breaking in a baseball glove:

Play catch with the glove as often as possible. This will help to loosen the leather and break it in.
Use a baseball glove heater or dryer to help warm up the leather. Be careful not to overheat the glove, as this can damage the leather.
Store your glove in a cool, dry place when you're not using it. This will help to prevent the leather from drying out and cracking.

With proper care and maintenance, your baseball glove will last for many years.

This is an email just received:

“Thanks Kevin! So far it is surprisingly doing the trick. Such a paradigm shift from hitting it with a mallet after drenching it in hot water .”

Let me dive a little deeper, parsing this brief email:

“…surprisingly doing the trick.” It’s no surprise to me that it’s working. We understand the science of leather so I know it works. It’s the nature of the chemistry to render a more supple leather after being treated. As leather experts we understand what works and what’s a joke. It’s simple, fast and yes, as noted does the trick. The only downside is so few people know about it. I can’t afford a giant marketing budget so this hidden gem, Mitt-Spit Break-In, is a product that actually performs as advertised yet so few people know about it. Help me spread the word.
“… hitting it with a mallet.” It is true, leather is really tough and can take a beating. Pounding the crap out of the glove takes a lot of energy for little real benefit. It’s hard to damage the leather by thumping it a bunch. It’s just not doing the leather much good. It’s the caveman approach when the science of leather has produced a more effective solution - Mitt-Spit Break-In.
.”… drenching it in hot water.” Now we’re over the edge. Hot water will have the exact opposite effect!! The leather will be permanently damaged with hot water. a.) The heat will cause the internal leather fibers to shrink. b.) The water will cause a pH reaction as the pH of the leather (acidic) and the pH of the water (typically alkaline) interact with a chemical reaction that causes the breakdown of the internal fiber structure. In a simple word, it causes the leather to rot. c.). As the wet glove dries, it will shrink and pucker, particularly along the seams. Leather shrinks if it gets wet. So the glove may lose its intended shape.

So yes Mitt-Spit break-in works. Whereas hitting it with a mallet is a lot of work with little pay off and soaking it with hot water damages the leather and will shorten the life of the glove.

Glove manufacturers should apply Mitt-Spit break-in at the factory so when the new glove is purchased, it is already broken in. What a novel idea!!

Why does Mitt-Spit Break-in work so fast in lubricating the leather fibers?

Again with the myths people have come up with to break-in a glove.
