I bought a bridle oh I'd say about two years ago. I *misplaced* it and it recently turned up! The leather is still in good condition, no cracks or anything like that, but it is SUPER stiff. What can I use to soften it before use?
I use Neatsfoot but brand of leather oil should work. Some people use olive oil if you happen to have that handy.. Just use a tack sponge and apply it till the leather has a light sheen on it.
I've actually dipped many pieces of leather straight into the oil and let it sit for a minute but many people here advise against that. Beware that oiling leather does tend to darken it. I love the look of well oiled tack though.
There are some products that break down the stitching on tack.
Really not true anymore. In the old days the thread used on tack was made from natural fibers. Not anymore - synthetics are used. Plus, I think that rumor got started so manufacturers could convince you to buy their fancy, schmancy leather cleaner and conditioners that cost a fortune.
Others mention Neatsfoot - great choice but make sure it's PURE Neatsfoot oil. It will darken your bridle. I prefer the dipping method myself, too.
Neatsfoot oil is made from cow byproducts. Now, how much more natural of a product can you use on leather?
Continued use of glycerin to clean will also keep it soft. Also made from cow byproducts.
