Vinegar based like tabasco. That much vinegar.
If so thoroughly clean the jars, dip in boiling water, air dry well, fill it with sauce and put it in a cabinet.
I dont bother putting hot sauce or BBQ sauce in the fridge, as long as it has vinegar. My tabasco and other sauces stay out. I do make sure the tops of the bottle is clean. So shake some out , wipe with a paper towel and eat.
