Leatherique shelf life?

I my opinion NO. I have been using it for twenty years and bought several gallons during that time, and never noticed age. Go for it! Its great stuff.
FYI, Hint. Shake it good. Use the oil first. It seems logical to me the reverse. But no. Oil, Pristine Clean, Damp cloth, dry cloth.

 

I believe it will be fine. I have some rejuvinator that is 15 years old and it works just like i did when new. Give it a good shake first.

 

I threw out a bunch of old Leatherique oil and cleaner recently.

It had separated out into the fats from the oil and, well, whatever else is in there.

Fats go rancid with time. I wouldn't use it if it's too old.

 

Its like Vinegar and oil salad dressing. Separation is normal to the product in my experience. No big deal, Shake, Shake, Shake
