    Anti-Rusting Agent

    I have learned sharpening before grinding, so now while grind, I still make frequent trips to sharpening station. Rusting on some steels is an issue, particularly with a coarser grind.

    Does anybody know of an anti-rusting agent that can be added to a water tank where I soak my stones and also rinse my knife during sharpening?

    Hi Marko. Super easy one. Add a little baking soda to the water. Regular Arm & Hammer stuff. Not sure how much, but a couple spoonfuls should do. I use it in my stone water and in my grinding buckets. It somehow changes the pH in the water making less acidic/basic or more magic - not sure. It works great.

    I tried baking soda and it works ok, TSP (Tri Sodium Phosphate) seems to work MUCH better at my shop

    I get it in the paint cleaning section of home depot.

    Thanks for the tip, Stephan. I don't know when I will go to Home Depot, so for now, I will use baking soda.

    Stephan, does the TSP bother your skin? I don't like to wear rubber gloves when I grind or sharpen.

    TSP can literally burn through your skin, in high concentrations over even just a few minutes. It's also really bad for the environment. I would go with baking soda based on these two factors alone. However, Stefan knows better than I do, and if it works for him, maybe it's a good option if the baking soda doesn't work.

    I put about two tablespoons in a 5 gallon bucket

    not sure how high of a concentration that is.
