If you wish to bate in the same de-liming solution, add  4 ounces of Oropon N-10(R). Stir the contents well, and place de-haired skins in the solution. Agitate skins frequently for 2 to 3 hours. Remove and rinse skins in clear water. Next set up acid and salt pickling solution and proceed with tanning process.
