Dried on dung often cannot be removed at green fleshing without damaging the hide or skin and only after soaking it is soft enough to be safely removed. To remove the stock for fleshing after soak can be labour intensive and time wasting and is better to lime flesh where ever possible. Soaking with enzymes, PELLVIT grades, improves the removal of dried on dung but the dung still tends to come away as lumps and these can block drainage holes in process vessels. Regular checks should be conducted to remove blockages.
Important: High amounts of dissolved dung / urine in soak will increase the growth of bacteria and the application of suitable biocides such as ARACIT must be used. Excessive amounts of dung call for increased offers of biocide.
Urine stains are sometimes a cosmetic problem but can also produce areas of putrefaction.
PELLVIT enzymatic soaking with BORRON enzyme compatible surfactants can be effective in helping to remove these stains and also bleaching in pickle can be effective.
