    Need help understanding why my pickle gets weaker after two deer capes.I always add extra acid as well as salt when I make a pickle bath but the ph always rises slightly just before second cape is pulled.I run each cape for four days ( not together ).Seems strange that the pickle weakens.

    The skin has its own moisture and pH that dilutes the pickle closer to neutral. The bigger the batch of pickle you make, the less spiking it requires.

    When I went from 2 gallons to 5 gallons, I experience less fluctuations. When I went to ten gallons, very little fluctuations.

    Citric Acid is what is used in canning, to keep fruit from turning dark. Switch to saftee acid,..it holds the ph better.

    Jimmy Rimrock Yeah, they come to snuff the rooster

    X2 for saftee acid, works way better for me. Makes getting to the end result of a tanned hide faster and easier.

    Every acid works well those who don’t understand this don’t understand the value of using citric ( which is in saftee acid) .
    It’s works great on greasy skins does make or aids in softer skins. Now different acids will swell the hides differently but unless you’ve been in this for yrs and used different acids you wouldn’t understand the minor difference. If citric was so good over saftee acids why do tanneries use citric , Formic alum? Reason they know how!
    All acids are acidic and will cause you damage if it gets on you. Formic will burn you as soon it touches your skin and the fumes take your breath away. To where citric, saftee acids will do the same as burn you ( but not harm your lungs) but it takes much longer hence it’s why they call saftee acid.
    Plus acids or pickles does not tan your hides any faster or easier.
